Gasoline Fuel System Problems of BMW 5 Series

Three wks ago my 08 528i was making a rattling sound in the engine, tin-can sounding. Took the car for service & they replaced my lifters and related parts. They said that the lifters are "known" for going bad on the 5 Series and it's typically due to seasonal changes. When my husband brought the car home to me I was very upset because the noise was still there, not as loud as before. I called BMW and made another appointment, citing that this problem had not been resolved and it needed to be looked at again. The appointment with a loaner could not be scheduled for another 10 days, so we waited. During those 10 days the vehicle started to take longer to turnover at start up. I would also feel the engine lightly shuttering as I drove at speeds averaging 35-50 miles per hour. Monday 05/23/11 was my requested appointment; however because my 15 mo. Old baby was ill we had to cancel. Thank goodness we did because my car would not have made it the 20 miles of freeway to the dealership. Today, 05/25/11, I made a left out of my neighborhood and as I accelerated approx. 50 yards, my engine bucked (felt like the bottom fell out), I lost speed dramatically. Suddenly, steering became nearly impossible and I was forced to "turn" into a small shopping center. However, I lost ability to steer upon entering the parking lot. My car would respond to nothing but the brakes (thank god those atleast worked). I looked down at my gear shift to attempt to reverse away from the curb and maneuver into a parking space, though my car was thrown into neutral & would not respond to anything but "park". I attempted to startup again but engine wouldn't turn over. It was dead. Within moments my abs, check eng, and battery lights illuminated & corresponding msgs came onto my communication screen. Car was towed. Awaiting dealership response in the am. After seeing prior complaints, I see someone needs to be fired. The us government needs to step in before people die! thank god my baby wasn't with me!.

2008 BMW 535i. Engine start-up takes longer than normal. The engine idles rough and hesitant to accelerate and check engine light comes on. BMW claims to have fixed the problem under a recall, but the problem came back again 3 days later.

While accelerating, the engine lost power and went into neutral. I was able to put it back into drive and the car very slowly regained momentum. A few minutes later, after the car had been turned off, I restarted it, put it into reverse to back out of a parking place, put it into drive to move forward, tried to accelerate, the car went into neutral again and would not move forward. I tried to put it into drive again but with no success. The car was dead and message flashed on "reduced engine power. " fortunately I was in a parking lot and not on a highway. The car had to be towed to the dealer. The rmfd high-pressure pump had to be replaced. BMW told me that this was a common problem and that the warranty on this part had been extended to 10 years, 120,000 miles. The old part is not available.

The contact owns a 2008 BMW 535xi. While driving approximately 65 mph, the accelerator pedal was engaged and the engine began to sputter with an extensive reduction in power. The contact continued with caution and the vehicle was taken to a dealer where they replaced the fuel pressure sensor, spark plugs and performed an oil change. The failure persisted. The vehicle was taken to the dealer three times in which there were no resolutions. The high pressure pump was replaced on a different occasion. In addition, when encountering a bump in the road and down-shifting from third to second gear, an abnormal clicking noise would occur. Recently, the engine warning indicator illuminated. The vehicle was in the process of being diagnosed. The failure mileage was approximately 45,000. Updated 01/28/11 updated 02/07/11.

Have had 3 separate instances in the past 9 months where my car stalled or sputtered with loss of power , and once I had no steering or braking ability. Dangerous situation in freeway traffic.

The car showed engine malfunction sign without warning in middle of busy street. All power, steering, everything went dead without warning. I couldn't move the whatsoever. I was lucky enough to make a right turn before this happened and avoid potential accidents.

Was driving at highway speeds when car began to "sputter" causing rough ride. After another 5 miles, the engine warning light came on. I pulled over to the side of the road, stopped the car, then restarted it. The light disappeared, but reappeared after another mile of driving. Contacted BMW who said the car was safe to drive. Service center found that it was stored fault codes, which a previous service bulletin had advised. These fault codes were cleared and the car functioned properly. Please note: this is for a 2009 BMW 535i. The choices available for 2009 BMW's do not include the 5 Series.

1. Rough riding - loss of power on highway 2. Dozens of times over the last few months. Car has been in shop for two months out of last 12 for the same issue. 3. BMW keeps trying different things but no final fixes as yet.

I bought a brand new BMW 525i m sport which has done 1000 miles. It is just 6 weeks old and the high pressure pump (hpp) went bust. I just can't believe it. I buy a car with my hard earned money and this happens. BMW should realize the impact it has on someone who expects a lot from his car since he is paying out of his nose.

I have a 2008 BMW 535i with sport package and premium package. I have had an "engine malfunction/reducing horsepower" issue with this car 3 times since purchasing it in August 2008. The first incident occurred within 3 weeks of delivery and only 600 miles. The second incident happened about a month later with approx 1500 miles; and the third incident occurred on 11/3/08 with approximately 2200 miles. BMW says each time that it's a misfire in one of the cylinders - but that they do not know how to fix it. So each time they reset the computer and send me away. This is a very dangerous situation. I drive on California freeways most of the time and when this engine malfunction occurs, the car starts "limping" and missing and I have to slow and pull to the side of busy, busy freeways that are very dangerous. Bimmerfest forum shows that there are lots of owners of the BMW 535i having this same problem - but BMW will not address the issue. . . . . . Each time the problem occurs, the BMW dealer asks me what kind of gas I'm using - and it's always been 91 octane. Then they ask me what brand - which is chevron, though I didn't realize the brand of gas would be a problem in modern day cars. This is a very dangerous situation to be occurring on the California freeway system, not to mention any freeway system given the speeds at which people drive and the danger of power loss in the middle of traffic and having to pull over on very small shoulders where other cars pass at high rates of speed within only a foot or two of my car when the engine malfunctions.
