My car is experiencing the infamous hpfp failure. The code thrown is p2aaf (fuel pump plausability) and p29f2 (high-pressure fuel system, fuel pressure). When starting the car, the engine shakes, rumbles and almost dies, erratic idle...I have to rev up the engine for a few minutes to keep idle stable. The check engine light and ses light comes on. It has reduced power, I can not accelerate quickly any more. I see people behind me move over everytime I go from a stop. I took the car to bmw recently and they found $8,800 worth of repair cost on the vehicle. I was told the hpfp needs to be replaced but it is out of warranty since the car is 10 years old and past 120,000 miles. They would not replace it for free. I was also told that the pump was replaced a few times before. I think I am the second owner of the car. I purchased it in 2/2013. Roughly 3 years ago, the car's engine shutdown while I was in the middle of the highway. I was able to keep it going about 4 miles an hour and pulled over. I was told the low pressure fuel pump was replaced under cpo warranty to get the car working again. This car is a danger to me and my kids. I think the hpfp should be replaced free of charge if the symptoms exist, no matter if their warranty has expired.

April 14, 2014 our car went in for service. May 7, 2014 it was returned for a 'reduced power,service engine soon'light. At that time, the fuel pump was replaced and covered under a recall. In july the light came on again and the battery was dead. We replaced the battery. In late august, the warning light appeared again. September 8,2014 the car went into the garage. At this time we were told it was most likely the turbo, est repairs at $5500.00. At this time the car had 83985 miles on it(the turbo was under an "extended" warranty until 82,000). I contacted bmw and ask for an extension on the warranty since we were less than 2,000 miles over. They agreed to pay for the part, but not the labor which is 2600.00. While I appreciate their effort, it is not enough. They obviously are aware that there is an issue with this part, since they extended the warranty so I feel that they should cover the entire amount. Yesterday the same warning light came on and has stayed on. The car is running very loudly, shaking, with little power. We are requesting your advice and/or assistance about what to do next. One thing I didn't mention was approximately one month after purchasing this pre-owned car, the engine had to be replaced with only 25,000 miles on it. So the current engine has approximately 55000 miles on it.

Vehicle lost power while on the highway, appears to be an engine malfunction. Took to bmw dealership and they replaced the fuel pump, however problem still occurs. Unfortunately, the warranty has just expired so I had to pay out of pocket. It appears many individuals have had the same issues with this particular yr, make & model so unsure of why bmw has not issued a recall to address the problem. This absolutely should be looked at by the manufacturer as from my experience with it occurring on the highway it can definitely cause an accident.

I own a 2008 bmw 335xi. The fuel system seems to have problem. I was driving on freeway, and the engine looses power suddenly on the freeway, the RPM drops, and I have to press the gas pedal hard to get to a comfortable speed of 60mph, the car still doesn't drive at full regular power. I first complained 4 months ago, they said it's nothing. I complained again a month afterwards. The dealer said there's a high pressure fuel pump recall and kept the car with them for 1 week. 3 months afterwards, this week, I experienced the same power loss again on a smaller scale. I didn't pay much attention, I took the car to dealer for regular service, the dealer said it has a recall again for the same fuel system issue - high pressure fuel pump loss of pressure. My car is still with the dealer, I don't know if and when they could fix it. I don't see a second recall on this issue yet. And bmw did not send me a recall letter yet. I think all of bmws twin turbo powered card should be immediately pulled off roads and checked and fixed before there's any loss of lives or property. At this point clearly, bmw doesn't seem to have a fix for this. A the federal safety agency investigation in to this issue would be appreciated and alert the public about the issue. Until this is fixed, bmw's twin turbo powered cars should be put on "do not recommend" list as far as safety.

Long crank, stuttering, engine dying at idle (or in traffic), check engine light/limp mode. Bmw dealers don't know exactly how to fix it once and for all. They just keep replacing the high pressure fuel pump.

2008 bmw 335xi: under moderate acceleration, car loses power and eventually stalls. Can sometimes be restarted, though it has completely failed as well. Can cause loss of control while driving vehicle. High-pressure fuel pump has been replaced twice and failure still occurs.

The car started but it started extremely "rough" with the engine rpms racing then dropping down to 500 rpms, feeling like it was going to stall. Eventually it evened out. Unfortunately starting issues are a frequent occurrence since I purchased this car and it has been to the dealer several times for similar starting issues. They replaced: the high pressure fuel pump which bmw knows it has issues with, made "software" updates, and replaced the dma. This time, however, when I began to drive it and turn on to a busy street, I essentially lost most of the power in the car. It was extremely disconcerting to step on the gas, expect the car to respond and it didn't. This could have been a disaster if it had happened while attempting to get on a busy freeway. Thankfully, it wasn't but I am worried it will happen again if I attempt to drive it to the dealer. After researching to see if others have had similar issues, indeed they have. All issues seem to be related to bmw's high pressure fuel pump issue, which they clearly have not solved given many have been replaced several times with the same unfortunate outcome of going bad again. I have had mine replaced by the dealer but am now having issues again. Detailed accounts are all over the internet (some serious safety issues as it has happened on the freeway) and I am surprised the federal safety agency hasn't done any serious investigation, nor forced bmw to recall either the vehicle or replace all parts that are affected and needed to correctly fix the issue (fuel pump, low pressure sensor, fuel injectors, etc.). I am considering contacting reporters because this is a toyota type safety issue waiting to happen. While it may only happen in a certain % of vehicles, does someone have to die to have this issue taken seriously and properly corrected? People have been "lucky" thus far, but this really is a safety issue and someone must force bmw to address it.

Bmw n54 engine 1. Symptoms begin with increasing long-cranks on start-up. Eventually the engine performs at reduced power, and ultimately total loss of power. 2. I am on my 3rd high pressure fuel pump (hpfp) with approximately 25,000 miles on the car in 2 years and 2 months of ownership. Apparently the replacement of the hpfp frequently leads to a problem with the spark plugs, and coils which cause severe mis-firing and violent shaking. My coils were replaced as was a catalytic converter and an o2 sensor in between hpfp #1 and #2. At times the engine has cut power while at highway speeds causing a hazardous driving condition. 3. Bmw made available a hpfp from a new manufacturer (my #2 hpfp) and subsequently discontinued that part (part # ending in 943) and replaced it with part # ending in 933, which is a re-manufactured hpfp (the pump currently in my car). Each of the three pumps appears to be nearly identical, each has a high failure rate and none seem to address the root of the problem.

While driving around 65-70mph, I experienced a complete loss of engine power, and had to pull over to the shoulder of the highway. I immediately restarted the vehicle and was left with 50% engine power (limp mode). Luckily the dealer was only a couple miles away, so I immediately drove there for repair, but had this been elsewhere in the region, I would have been stranded. The bmw high pressure fuel pump was replaced and the car has been working well ever after. I was told that this incident accurately reflects what typical high pressure fuel pump (hpfp) failures typically present like.
