装B 发贴！欢迎口水！BMW宝马新5系520LI 523LI 530LI/530li/535Li 5改7系740LI双出后扰流全新一代BMW宝马5系520LI 523LI 530LI/535li/550Li 个人感觉5系和7系没什么差别，刚好在在一个QQ群里见到广州达标改装配件发广告说可以把F18 520LI 523LI 530LI/535li/550Li 进口的短版5系也可以改740LI的后面（虚荣心作怪了）。

哈哈！QQ联系了DAB的业务人员经过3天的沟通我确定自己做做白老鼠了，（他们说已经卖了很多，JS的话不要全听，我选择了淘宝付款，呵呵！到时有什么不对直接不要，差评就可以了，呵呵）经过DAB包围改装的业务员的解释大概明白怎么样改了：那就拍了下来吧！等了大概4天快递终于到了，坚持包装没我问题，我就第二天拿去给我下面的修理厂去问师傅，安装和喷漆多少钱，那师傅见到我买回来的东西，说：可以安装：喷漆收我300块（比SSSS店便宜多了）安装费200块，工程开始了，打开产品看到里面有张安装说明书，和之前DAB业务人员说的一样，一个仿740LI挡板，2个内支架，一个740LI的标（我想已经是拿来固定在杠里装排气尾口的）还有一对740LI的尾口，我问师傅，这尾嘴是不是正品的，师傅看了一下，说是正品，电镀和做工仿的做不了这样的，然后我看到上面怎么有中国制造的英文，我就问师傅这是不是假的，师傅说你傻了，现在包括760LI的这些尾嘴都是中国制造的，（汗！！！看来没买进口的是明智的选择）打消了我的疑问了，师傅就开始安装了，安装工程我来说一下：先要把后杠拆下来，把那个内支架先安装在里面，外面用螺丝固定，我的是用拉钉固定的，师傅说这样奈用点，哦！哦！哦！然后就要把原来排气的尾口切割掉（伤心太平洋啊```！这个问题购买的时候DAB包围的业务已经说清楚了）我的是520LI单边排气的，所以要再去改，如果是520LI 523LI 就需要去改双边排气了（因为如果你另外一边不出烟天气冷了很明显露馅了，丑死人，现在还没问题！年前再花这个钱吧），再把740LI 的尾嘴安装上保险杠去，打上螺丝，非常好！但是我就又有疑问了，问师傅那之前打了拉钉的怎么办，好丑！师傅笑了一笑，人家可以设计出来已经想到这点了，把那仿740LI的挡板拿过来，盖上去，位置非常密合，在配上3M胶和几点玻璃胶，几乎看不出来是是加装扣上去的，（奶奶的不怪之得他们肯淘宝拍啦）原来是这样，一直以为无奸不商，看来广州那些卖汽车配件的还是有点人才在的，呵呵！！！然后就把原来那讨厌的520LI的标去掉，装到右边尾箱大功告成！呵呵！我和师傅说我可以走啦？师傅说：你还喷漆哦！哦是哦！太高兴了，师傅说这些加装的本来就没想他位置这么合，想装了再喷漆，可以打腻子补一下，所以才先装再喷漆，他说现在看来是多余的了，但是还是这样安全点，哦！哦！哦！又明白了一个道理了！+1 那我问师傅什么时候喷漆，他说你明天下午过来拿车吧！明天？好煎熬啊！好吧！负责今天星期6没什么事，回家写论坛去！星期天中午起来，一般我是下午才起来的，昨天晚上一个通宵！但是为了看看我的520LI变身740LI起早点啦！走下去下面的修理厂！我问师傅我的车好了没有，他说等一下，喷漆好了，帮你抛光一下！哦·哦·我就过去喷漆房那里看看，偶滴神怎么我的车牌挂在740LI上来了，难道老板这么好！7系换我5系？？哈哈！！醒醒吧！已经是下午不是发梦的时候了，好吧，就给他们继续抛光吧！等了大概1个小时终于把我的740LI开出来了（马上个人感觉和身份+1）哈哈！左右看了一遍不是很相信自己的眼睛，哈哈！！！出去丈母娘那里接老婆去，哈哈！！到了丈母娘里在乡下，老婆出来见到刚停车，就问，咋把我们的牌挂在740LI上面啊，老公你是不是有神经病啊！那来的钱换车啊！我笑了一笑说，你进去看，是不是还是和之前的一样？还有你送的东西还有？老婆说是哦，那怎么屁股变740LI的了！（郁闷的女人，难道改了贴了个740LI就是7系了吗？唉！）然后我就和我老婆解释了怎么样5改7 （我家女人不给我改车的，之前想改M5款的就是因为这个事才跑到丈母娘家的住了几天）。

宝马5系易出现的故障与缺点宝马5系最大缺点有异响!!!当前词条：宝马5系缺点来源：网上车市网友或论坛新宝马5系总体来说还算是非常值的一款车，但这个异响问题确实让人头疼。

最初，刹车溜滑时有非常响亮的口哨声，整得我当时环顾四周还以为是旁边的公交车。

然后，方向盘转动时发出吱嘎吱嘎的声音，原地打方向也很明显。

然后，安全带卡扣摩擦的声音。

后来，口哨声莫名其妙得消失了，安全带卡扣声也减轻了。

首保时，4S店解释说各类异响均是因为宝马装配工艺比较严谨，所以难免会有摩擦声。

对于这种说法，本人是绝对不认同的，严格说来，宝马5系的内饰做工不仅谈不上细致严谨，反而比较粗糙，内饰衬板的接缝不小，尤其AB柱与车门内衬板的接缝有非常明显的缝隙，甚至可以看见里面的胶。

总之，对华晨宝马的装配工艺很是无语。

方向盘异响问题，4S店打了点油，说是已经解决了。

之后很短的一段时间声音确实是消失了，但是近几天又出声了，而且比以前更明显，吱嘎吱嘎得听着让人头疼。

好嘛，这两天溜滑时又出了一种新动静，不再是以前的口哨声，是刹车片摩擦的声音。

根据以往驾驶经验，或许是因为刹车片表面不干净，积累了一些杂质；当然，实在不希望是别的问题。

宝马5系车主谈谈使用缺点当前词条：宝马5系缺点来源：网上车市网友或论坛因为国产的宝马5系我开确实没用，宝马5系后排从来不坐人，而且我更喜欢进口内饰的色。

下面说说开了一万公里的感受:动力方面，再轿车里算是出色的了最起码，而且这车开着很舒服，真的比奔驰开着舒服。

但是后排坐着真的很憋屈，前排的椅子太大，坐后面啥也看不见，加上进口的又短点，可能国产的能好一些，不过又不是7系我要求不能太多，毕竟价钱在这呢，不可能面面俱到。

发动机的声音有点像拖拉机，问过4S店，说是涡轮的原因。

音响方面我只能说很一般，是不是豪华的就能好一点。

油耗方面我倒是很满意。

On the IHKA high and basic versions, thetemperature and air volume are controlled by means of rotaryselectors.- Extended air conditioning functions such as air stratification orindependent heating (option) are selected and activated by means of the controller in the central information display (CID).- Three different AUTO programs can be set in the CID by means of the controller:soft,standard,intensive.The settings have an effect on the flaps program and on the flaps and blower program.-Modified display concept:-Scope of display elements for the extended A/C functions in the CID similar to those in the E65. The required fan and temperaturesettings are not shown in the CID. The set values for temperature and air volume can be read off from scale rings(air volume in IHKA high: with LED illuminated ring). In the IHKA basic version, airdistribution is set manually at the IHKA control panel/control unit.In the IHKA high version it is set by means of the controller in the CID.-The liquid crystal display from the E39control panel is not installed in the E60.-Only stepper motors are used to actuate the flaps, i.e. no bowden cables.-Separate footwell flaps for left and right (IHKA high only)-Separate ventilation flaps for left and right (IHKA high only)-Suction-action blower arrangement in the air conditioner:The blower is arranged behind the evaporator.The heat exchanger for the heating system is positioned at right angles with respect to the evaporator and is arranged over the blower. This arrangement makes for a very compact air conditioner unit.-The heat exchanger for the heating system (HWT) is identical for the IHKA basic and IHKA high on petrol engine vehicles. A heating heat exchanger with an integrated electric auxiliary heater is fitted on diesel engine vehicles. This heater is also of identical design for the IHKA basic and IHKA high.-Clutchless,externally actuated and output-regulated A/C compressor (E65 common part)-2-gas sensor for automatic recirculating air control (IHKA high only, E65 common part)-Solar sensor located in centre of instrument panel in area of defroster air vent (IHKA high only, E65 common part)- Advantages of the system-Even though the efficiency and functionality of the automatic climate control IHKA have been further improved compared to thepredecessor versions the size of the unit is considerably morecompact than in the E39.-The electric auxiliary heater based on the PTC principle in diesel engine models speeds up the rate the vehicle interior is heatedparticularly at low outside temperatures and during the cold start phase. The windows are also defrosted at a faster rate.-Thanks to the PTC characteristics, the heating elements of the auxiliary heater are intrinsically safe, i.e. they are protected from overheating.-The condensation sensor detects the threat of windscreen misting (condensation) even before it is visible. Misting (condensation) is prevented or automatically eliminated with the aid of the IHKA(IHKA high only).-The progressive evaporator temperature control (2 - 8ºC) ensures a lower level of air dehumidification,thereby reducing the drying effect for mucous membranes while resulting in a measurable fuel saving.IHKA basicThe IHKA basic is fitted as standard in E60 ECE vehicles. The design, function and output of the integrated heating and air conditioning control system (IHKR) installed at the basic version in the E39 are not comparable with those of the IHKA basic in the E60.- New system features-No bowden cables from the control panel to the air conditioner as the flaps in the air conditioner are actuated solely by stepper motors.-New control panel and control unit with extended functionality even in the basic variant: automatic flap control, temperature stratification setting for centre air vents via controllers and CID, OFF button,interior temperature sensor (force-ventilated).-Local interconnect network bus (LIN bus) for controlling the flap stepper motors, the electric auxiliary fan based on the PTC principle and the blower motor in the air conditioner.-Electric auxiliary heater based on the PTC principle (diesel models only).System overview- Positions of the components in the vehicleKT-11245Fig. 1:IHKA basicIndex Explanation Index

compartment on diesel engine vehicles with independent heating.The system overview for the independent heating is described in the chapter IHKA high.Components- IHKA control panel/control unitThe control panel/control unit controls the following functions:-T emperature setting (no right/left separation)-Air distribution: windows, upper body, footwell-Air volume (blower setting)-Air conditioning ON/OFF (refrigerant compressor)-Automatic air distribution-Outside air or recirculating air-Rear window defoggerExtended functions such as air stratification and independent heating (option) are selected and activated by means of the controller in the CID.DesignThe IHKA control panel/control unit consists of5buttons with indicator fields and 3rotary knobs. The force-ventilated temperature sensor for measuring the vehicle interior temperature is also accommodated inthe IHKA control panel/control unit.KT-11117Fig. 8:Design of IHKA control panel/control unitIndex Explanation1Rotary control for air distribution2Opening for force-ventilated vehicle interior temperature sensor3AUTO button*4Rotary knob for blower adjustment (air volume)5A/C button*6OFF button*7Rotary control for temperature setting8Outside air/recirculating air button*9Independent heating indicator */**10Rear window defogger button** with function lighting** light module for independent heating is always fittedFunctional principleThe IHKA control panel/control unit features 3controls with fine settings (24 and 36 positions) for air distribution, blower setting, air supply and temperature setting.The recirculating air button, AUTO button (automatic air distribution) and the A/C button feature a green function light (LED).The button for the rear window defogger and OFF button have an orange function light (LED).A red LED indicates operation of the independent heating option(SA536):-Timer activated: LED steady light-Function active: LED flashesWhen the light is switched on,the locator and function indicator lighting is activated via terminal 58g. The signal comes from the light module (LM).The locator and function lighting is dimmed:-Dependent on the position of the dimmer control on the light module -Dependent on the ambient brightness (photocell on light module)The independent ventilation and residual heat functions are not included in the IHKA basic version.With the recirculating air function selected,after12minutes,the system switches to partial fresh air for 1 minute. The counter for the recircu-lating air time is restarted when the recirculating air function is switched off and then reselected.The refrigerant circuit need not always be activated in recirculating air mode.The IHKA control panel/control unit features 2plug connections at the rear. The holder for the interchangeable sensor blower for ventilatingthe integrated interior temperature sensor is also located at the rear.These plug connections connect the IHKA control panel/control unit to the vehicle electrical system and the heater/air conditioner.KT-11115Fig. 9:Plug connection, IHKA control panel/control unitIndex Explanation118-pin plug connection to vehicle electrical system212-pin plug connection to heater/air conditionerThe following hardware variants are used for the control panel/control unit IHKA basic and IHKA high:Variant Basic High ECE version with independent heating*X XUS version with independent heating**-X ECE version without independent heating X-US version without independent heating**--* with temperature indication in ºCelsius** with temperature indication in ºFahrenheitNote: The table describes the functionality of the control unit irrespective of whether independent heating is installed or not.

The air temperature at the centre air vent can be raised or lowered with respect to this central presetting.KT-11534Fig. 11:Independent heating display in CIDIndex Explanation1Independent heating: switch-on time 12Independent heating: switch-on time 2Special functions of the rear window defogger (HHS)-With the IHKA control panel/control unit switched off(air conditioning functions OFF)the rear window defogger function can be activated by means of the rear window defogger button irrespective of the other settings on the control panel. All other air conditioning functions remain in OFF mode, the function lighting OFF LED remains active. -When the IHKA control panel/control unit is switched on and the rear window defogger function active,the rear window defogger function is also switched off when the control panel is switched off by means of the OFF button.-If both OFF mode and the rear window defogger function are active, pressing any button (except the rear window defogger button),turning the rotary control or adjusting the A/C setting on the CID will switch the control panel on again.The rear window defogger function will remain active.If only the rear window defogger button is pressed, the OFF setting is retained and the rear window defogger function will be deactivated.- Heater/air conditioner IHKA basicThe package space required for the air conditioner in the E60is smaller than that in the E39 and E65. The modified arrangement of the heatexchanger, evaporator and blower compared to the E39 facilitates the more compact size of the air conditioner (see Fig. 14).There are a total of 4 air conditioners: air conditioner IHKA basic andIHKA high each with and without an auxiliary PTC electric heater. The changes in the various types of heater/air conditioner relate to thewiring harness, air distributor housing, the flaps and stepper motors,the coolant connections as well as the heating system heat exchangers.KT-11465Fig. 12:Left view of air conditioner, IHKA basicIndex Explanation1Air conditioner/bulkhead screw mounting point2Y-connector: common heating feed, left/rightKT-11464Fig. 13:Right view of air conditioner, IHKA basicIndex Explanation1Central connection for sensors and stepper motors2System connector, blowerDesignKT-11463Fig. 14:Evaporator, blower and heating system heat exchanger, IHKA basicIndex Explanation1Blower2Evaporator3Heat exchanger for heating systemKT-11367Fig. 15:Stepper motors and temperature sensors, IHKA basicIndex Explanation1T emperature sensor, heat exchanger2Stepper motor, fresh air/recirculating air, right3Stepper motor, ventilation4Stepper motor, cold air5Stepper motor, fresh air/recirculating air, left6T emperature sensor, evaporator7Stepper motor, defrost8Stepper motor, footwellStepper motors6bipolar stepper motors are installed in the IHKA basic.The motors are designed as MUX5motors (multiplex motor type 5).The differences compared to the MUX4motors used in the E65are found in the actuation software. On actuation, the stepper motors are receive their voltage and ground supply from the IHKA control panel/control unit via the LIN bus.Fig. 16:Flap motor with gear mechanism, drive, electronic moduleThe stepper motors for the fresh air/recirculating air flaps are designed as high-speed motors.The number of steps of the stepper motors depends on the adjustment range of the driven flap as follows.KT-11220Blower with blower controllerAn electric blower for generating the necessary air volume is fitted in the heater/air conditioner. The blower features a symmetrical design and is equipped with two dual suction-action radial fan wheels (four-flute blower).KT-11218Fig. 17:BlowerIndex Explanation1Blower controller on blower motorThe blower controller is mounted directly on the housing of the blower motor.The controller features self-diagnosis capabilities and is actuated by the control unit in the IHKA control panel via the LIN bus. It is possible to replace the fan motor without the need to disassemble theinstrument panel.- Microfilter system/intakeThe IHKA basic operates as standard with a microfilter system (MFS) for interior ventilation in the E60.An activated carbon microfilter is fitted in the IHKA high version.Based on the operating time and operating parameters, the "filter condition detection" function determines the load status of the filter without additional sensors.In this way,due service dates for the vehicle are calculated together with other wear-registering components.After changing the filter, the CBS system must be reset via the instrument cluster or in the tester.Recorded parameters for determining the filter load status:-Blower voltage-Road speed-Outside temperature-Rain intensity (IHKA high only, otherwise default)-Sun intensity (IHKA high only, otherwise default)-Day counter-Mileage (kilometer reading)Particular care must be taken when mounting the air conditioner on the inner side of the bulkhead to ensure the seals are fitted correctly. The butyl beading on the seals provides a tight seal with the bulkhead.When assembling, make sure the repair instructions are followedprecisely (contact pressure, duration, component temperature).In the same way as for the seals, particular care must be taken when installing (position of seals) the filtered air duct and the filtercompartment covers. Secondary air may be drawn in from the engine compartment if the seal in the transition of the components in the air duct between the filter and air conditioner is defective.KT-11707Fig. 18:Bulkhead with filtered air duct (without intake/microfilter)Index Explanation1Intake/filter compartment seal2Threaded connection, filtered air duct3Filtered air ductKT-11709Fig. 19:Bulkhead with seal for filtered air ductIndex Explanation1Bulkhead/filtered air duct seal2Aperture for expansion valve3Aperture for water connections, heating circuit4Aperture for air conditioner and screw mounting points and sealsKT-11708Fig. 20:Microfilter systemIndex Explanation1Microfilter compartment2Water drain3Bulkhead/filtered air duct seal4Filtered air ductSystem functionsSystem functions in control panel/control unit IHKA basic System functions in control panel/control unit IHKA highHeat exchanger control Heat exchanger control with left/rightseparationInterior temperature control Interior temperature with left/right separation Evaporator temperature control Evaporator temperature controlVentilation temperature control (stratification)Ventilation temperature control (stratification)No automatic blower function Automatic blower control with solar sensorinfluenceAutomatic air distribution without left/right separation Automatic air distribution for defrost Automatic air distribution with left/right separation for footwell and ventilation Individual air distribution defrost 0-100% Individual air distribution footwell and venti-lation 0-100% with left/right separationRecirculating air mode Recirculating air modeAutomatic recirculating air mode with two-gas sensor controlWater valve actuation Dual water valve actuationDefrostMAX ACResidual heatFogging (condensation) avoidance in AUTOprogram (condensation sensor)Solar sensor: air volume/temperatureadaptation with left/right separationT emperature control, rear compartmentstratificationKey memoryCar memorySensor inputsRear window defogger actuationHeated washer water jet actuationActuation of A/C compressor, A/C compressor inlet, A/C compressor protection functions Calculation of load moment of externally controlled A/C compressorActuation of electric fan on cooling module via K-CANControl of progressive evaporator temperatureActuation of stepper motors via LIN busActuation of blower via LIN busActuation of electric auxiliary PTC-type heater via LIN busElectric load cutout, electric auxiliary heater by DDE/DME (looped through)Interaction of IHKA control panel/control unit with man-machine interface(MMI integrated in M-ASK or CCC)Actuation of auxiliary water pumpLED dimmerActuation of independent heatingCalculation of air filter status (CBS)Flash programmingSelf-diagnosis, IHKA control panel/control unitDiagnosis of stepper motors on LIN busDiagnosis of blower output stage on LIN busDiagnosis of electric auxiliary PTC-type heater on LIN busSystem functions in control panel/controlunit IHKA basic System functions in control panel/control unit IHKA high- Vehicle interior temperature controlThe IHKA control panel/control unit is the central control module for temperature control in the vehicle interior.The required temperature (setpoint) is set on the IHKA control panel/ control unit by means of a rotary temperature selector.The temperature is controlled with the aid of the ventilated interior temperature sensor in the IHKA control panel/control unit.The mass air flow for temperature control of the vehicle interior is produced by a radial blower in the air conditioner. T ogether with the road speed(K-CAN signal)backpressure compensation is realized with the fresh air flap/recirculating air flap for the purpose of maintaining the mass air flow in the air inlet ducts as constant as possible at different driving speeds.In a reheat process, the mass air flow in the air conditioner is initially cooled and dried at the evaporator (provided the A/C compressor is switched on) and then heated to the set temperature at the heating system heat exchanger (HWT).The temperature at the heat exchanger is controlled by means of a temperature sensor on the heating system heat exchanger and a clocked water valve that is actuated by a PWM signal.A heat exchanger characteristic map defines the opening times of the water valve depending on the engine variant and engine speed.A water pump and an auxiliary electric water pump provide the necessary water throughput in the heating circuit.The evaporator temperature is controlled by means of a temperature sensor on the evaporator and a controllable expansion valve. An output-controlled refrigerant compressor generates the pressure in the refrigerant circuit and therefore the necessary low-temperature energy in the evaporator.A progressive evaporator temperature between2and 8ºC facilitates an effective reheat process used to optimize the energy output.Inclusion of the outside temperature via the K-CAN guarantees a subjectively perceived uniform interior temperature at different outside temperatures.The temperature for the driver and passenger can be set separately in the IHKA high variant. This requires a heat exchanger with left/right separation. T ogether with the IHKA control panel/control unit, a dual water valve in the heating feed circuit and two temperature sensors on the heat exchanger form the heating control circuit.In the IHKA high variant, solar sensors for the driver's and passenger's side compensate for additional temperature influences of the sun.- Air distribution-Individual air distribution setting(360ºrotary control with36positions) -Automatic air distribution (AUTO button)The air volume of the blower remains unchanged when the automatic air distribution setting is changed by means of the "air distribution" rotary control. The function light in the AUTO button goes out.An important prerequisite for optimum air distribution is that the manually adjustable air vents are open.。

宝马5系试乘试驾车加油跳枪1.客户反映：公司新车管理员反映，宝马525LI试乘试驾车加油跳枪。

刚开始以为加油站油枪有问题，所以换了台加油机，继续加油跳枪。

因为车辆没有太多燃油，决定换一个加油站试试。

到了新加油站加油，故障依旧。

2.故障再现：此车为公司的试乘试驾，BMW525LI,已经行驶2125KM.陪同新车管理员一同加油，只要一开加油枪，油枪就跳枪，尝试减小油枪开度，非常缓慢加油，依然跳枪，更换其他加油枪，试车，故障依旧。

3.维修分析：用宝马诊断电脑进行检测，没有存储任何故障代码。

1.怀疑碳罐电磁阀损坏，碳罐电磁阀一直处于关闭位置，造成碳罐吸收汽油蒸汽能力饱和，排气不畅，形成加油跳枪。

手动添加碳罐电磁阀的检测计划，对电磁阀进行控制，能够听见“嗒嗒嗒”的声音，说明碳罐电磁阀的功能正常。

2.怀疑碳罐堵塞，因为此车仅行驶两千多公里，检测碳罐时也是半醒半疑，拆下碳罐，用嘴吹碳罐下面通大气的通气孔，上面有气流出来，说明碳罐没有堵塞。

3.怀疑燃油通气管路堵塞。

在燃油箱上部有一根通向燃油加注口，再有燃油加注口通过三通管通向碳罐的燃油蒸汽通气管。

此通气管正好在中部有一个接口，上面通向燃油加注口及碳罐，下面通向燃油箱内部的通风阀。

断开通气管，向通气管上部吹气，在加油口明显有气流通过，说明上部通气管路正常。

向下部通气管进行吹气，管路不通。

因为此气流是通向油箱，在油箱加油口有一个单向阀，此单向阀正常情况下为关闭状态，此时向油箱吹气，不通也很正常，如果打开此单项阀向油箱吹气，如果不通，说明是油箱内部通气阀损坏，此通气阀是集成在油箱内部，如果损坏，需要更换油箱。

基于上述维修思路，用宝马抽油机管路倒开单向阀，在燃油通气管进行吹气，气流正常，说明燃油箱正常。

就是在往燃油加注口下抽油管是感觉很不顺畅，对比其他车辆确定此车不正常，感觉此车燃油加注口下面有异物。

拆下燃油加注管，发现内部又有一个小管子，此小管不是原车的，是掉进去的，此车为什么会掉进去一个小管，开着车人太多，现在也无从考证。
