These vehicles are equipped with passenger frontal air bag modules using certain air bag inflators that may not vent properly in the event of a crash necessitating deployment of the passenger frontal air bag. If the inflator cannot vent properly, the inflator may rupture, resulting in metal fragments striking the vehicle occupants and causing serious injury or death. BMW has notified owners, and dealers will replace the air bag modules, free of charge. The recall began on March 20, Water and debris may enter the front driveshaft's universal joint, causing excessive wear and possibly resulting in the joint's failure. If the front universal joint fails, the front wheels would not be driven, affecting vehicle traction. Additionally, continued driving of the vehicle with a broken front universal joint may damage other components. Either condition may increase the risk of a crash. BMW will notify owners, and dealers will replace the front driveshaft, free of charge. The recall is expected to begin April 24, These vehicles may have had a driver-side air bag module installed as replacement equipment such as after a vehicle crash necessitating replacement of the original air bag, or as a remedy part for a prior recall. These replacement modules contain an air bag inflator that may rupture due to propellant degradation occurring after long-term exposure to lower absolute humidity, temperature and temperature cycling. In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death. BMW will notify owners, and dealers will inspect the driver side air bag module, replacing it as necessary, free of charge. The recall is expected to begin March 15, Virgin Islands, or "Zone A. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to high absolute humidity and temperature cycling. An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death. BMW will notify owners, and dealers will replace the front passenger air bag inflator or air bag module, free of charge. Interim letters informing owners that parts are not yet available are expected to be mailed March 1, Owners will receive a second notice when remedy parts become available. The affected vehicles have a Digital Motor Electronic DME control unit that may have a loose electrical ground cable, possibly causing an under-voltage condition which would result in the transmission shifting to neutral. If the vehicle unexpectedly shifts to neutral, there would be an increased risk of a crash. BMW will notify owners, and dealers will tighten the ground cable, free of charge. The recall is expected to begin February 6,

The self-leveling suspension is a further development of the EHC system as already used on the 5 Series and X5. It prevents intervention in the case of other causes. This makes it possible to gear the intervention to each situation as regards optimum frequency, target height, tolerance thresholds and battery load. In addition to handling the self-leveling suspension, the control unit has the task of monitoring the system components, saving and displaying faults. The task of the self-leveling suspension is to bring the vehicle ride height at the rear axle back to the target level if the load changes. The self-leveling suspension works by feeding or extracting air into or out of the bellows. The height sensors provide the control unit with information on the heights of the left-hand and right hand sides of the vehicle. If the heights are outside the specified tolerances, the system intervenes using the air supply unit to set the nominal ride-level height. Changes to the load mainly take place when the vehicle is at a standstill, before or after a journey. In order to distinguish load changes from other disturbances such as road irregularities, the height signals are filtered through two different low pass filters with different limit frequencies high and low frequencies. Various signals and messages indicate the different driving conditions to the control unit, which switches into various operating modes depending on the condition. Intervention modes The operating modes intervene depending on the vehicle condition or suppress interventions. In the Sleep mode, no intervention takes place. The load-cutout signal is set by activities on the vehicle such as pressing the door handle or operating the central locking system and output on the K-CAN. In the case of ignition key position terminal R or terminal 15 or engine on signal, the signal is set permanently. If the vehicle is parked, the load-cutout signal remains set for approx. If a door status changes within these 16 minutes, the after-run time is restarted. When this after run time expires, the message switch off consumers is sent and the control unit switches for 1 minute into the Post mode before it goes into the Sleep mode. In the Pre mode, the vehicle can only be raised to its specified height if the level drops significantly below the specified height. The intervention tolerance range is 40 mm from the mean value. This intervention tolerance ensures that the vehicle is only raised for heavier loads to increase ground clearance before driving off. Smaller payloads only lead to small amounts of spring travel which are only balanced out after the engine has been started. This setting reduces the load on the battery. The vehicle is lowered when the mean value of the two height signals greater than 0 mm AND one side is above 10 mm. For the decision regarding intervention in this mode, only the mean value of the two height signals fast filter is analyzed. Interventions that were started in other modes are continued with the internal tolerance ranges that apply to these modes. There is no inclination detection in the Pre mode.

In this guide, you will learn about common problems that cause BMW engine malfunction and how to diagnose the problem yourself. When the BMW engine malfunction message pops up on your iDrive the check engine light service engine soon may also come on. The color of the check engine light can help you get an idea of how serious the problem is. To find out why you are getting this warning start by reading the fault codes by connecting a BMW scanner to the OBD-II port under the dashboard on the driver's side. Most BMW engines are equipped with Valvetronic. It variates the amount of intake valve lift, eliminating the need for a throttle plate. Although this is a quite complex system, it is quite durable. If it fails, you might have poor throttle response and lack of power. Usual failure points are an electric motor and an eccentric shaft position sensor. Vanos is operated by oil-powered actuators. It is a very simple and robust system. In most cases, it will fail if there is an oil sludge buildup within the Vanos solenoids. This is a result of too long oil change intervals. Luckily, faulty Vanos solenoids are an easy and cheap thing to fix. BMW engine control uses readings from upstream O2 sensors to achieve optimal engine performance. Upstream O2 sensors can get fouled by excessive fuel or oil consumption. Furthermore, a damaged wiring or a loose connector is also possible. Ignition coils can fail from a number of reasons. It will result in a misfire, causing the engine to shake and judder under acceleration. Misfire is very damaging to your catalytic converter, so don't drive your BMW with a misfire. Ignition coils are easy to replace, so it's a good idea to have one spare ignition coil. Timing chain-related problems can trigger a 'check engine' light. Although timing chains are supposed be a life-long item, they can get exclusively stretched with time. Tensioner or plastic guides can fail, too. BMW are very senstive to the voltage and if the battery is old, it may hold a proper charge. If your battery is over 7 years old it is time to change it to avoid other electrical issues. A bad alternator regulator can cause similar symptoms as well. This is a delicate system which can be damaged by a low-quality fuel. High-pressure fuel pump and injectors are the usual failure points. In most cases, power output and acceleration are heavily affected. You must check and replace the faulty pump or injectors as soon as possible.

New to this forum, main reason for joining is I have a D which I like very much, but my car is randomly indicating the following "Level Control System Failure, concerned that the car has only done miles and it keeps popping up with this. It may just be a perrished pipe or worst case scenario the compressor. I have had the problem with my M Sport This meant that it was pulling dirty air into the compressor and it wasn't able to pump up the suspenssion fast enough. I had the hose changed and the compressor and I have not had the error since - although I only got my car back 1 week ago Yeah try the pipe thing first, BMW seem to only want to change both if you have an issue. I gave exact details on a post here somewhere. BMW Uk washed their hands of it complete, sticking to its not in warranty so there. Pretty bad when you consider the car had done only miles, must be the BMW quality fairies. As already said the air intake hose is the culprit. If the pipe has already broken, dirt is drawn in the compressor and it will need replacement eventually. Changing the compressor is easy 30 min job after you lift up rear right side. Here are more reasonable prices for compressor and additional parts. Garage also said the tyres at the front had slight bulge on them, may have hit a pot hole in its life so far, but were good for now. And to add to this while driving home yesterday car got a stone chip, thought ok Auto glass sort that out easily. Crack carried on to the other side of the screen.

Remember Me? Second Lieutenant. Right now the car is down all the way where I can barely get one finger between the top of the tire and the fender looks nice as hell lol and the ride is crap and bouncy as hell. Anyone had this before? Attached Images. Appreciate 0. I had a similar issue at one point and found that one of the rear self-leveling links came loose. In the picture below its the small link next to the purple arrow. Granted this pic isn't from an X5M it is very similar looking. Appreciate 2. Originally Posted by Dadad.

After going for wheel alugment my suspension has gone lowered completely and is not coming up. It shows exactly the same message. While i went to the garage, the system showed vehicle lighting failure and i couldnt turn off my lights. Nor coild i pull up the windows neither could i unfold my side mirrors. But after a restart. All the features are working perfectly fine. Just for information i got my battery changed yesterday. Can anyone help me in this sutuation please. Originally Posted by Khasoosi.
