#2376 of 2735 High pressure Fuel Pump
Sep 14, 2009 (1:56 pm)
A while ago I received some correspondence from BMW regarding the fuel pump on my 2008 535I. To be honest I paid no attention to it but I think it related to extending the warranty on the fuel pump. The other day I was doing about 65 on the Garden State Parkway and I felt the engine lose power. The car would still do better than 60 but it lacked power and the turbo wouldn't kick in. The dash lit up with an engine that looked like it was half lit and a message came up saying that there was an engine malfunction and I had reduced power. I got the car home without incident and went on Google to see if anyone else had the same problem. I found numerous instances of other owners on other BMW sites having the same problem and the cause was a malfunnction in the high pressure fuel pump (HPFP). I called my dealer (Park Avenue BMW) and explained the problem and they said to bring the car in at 6PM and they would give me a loaner(which turned out to be a 2009 528) . By noon of the next day they called and said the car was fixed . They replaced the fuel pump. Park Avenue really did a great job for me.
Has anyone else with a 2008 535I experienced this problem or heard about it?

BMW is having some issues with the HPFP used on the N54. Some cars are affected and some aren't. There are quite a few discussions about it on various E90 forums and message boards.
#2378 of 2735 Starting problems on 2010 535i...HPFP
Sep 15, 2009 (8:22 pm)
Got my 2010 535i with M sport package on Aug 28, 09. At 850 and then 1000 miles, I had the High Pressure Fuel Pump (HPFP) go out. The car would start but it would sputter. BMW issued a bulletin on July 5, 2009 on the issue actually so it’s well known. I am surprised and perturbed that BMW did not rectify the problem for the 2010 (vehicles with the twin turbo).
The symptoms are as follows:
1. Sputtering of the engine when trying to start.
2. Delayed start
I learned per the BMW service advisor that the HPFP provides pressure for the fuel line when the engine is off. When the HPFP fails, it does not provide the pressure so the start delays and hence the sputtering.
BMW of Fremont fixed it in one day.
They replaced the HPFP, tested the car, waited, and tested it again. So far so good but we’ll see. Hope this post helps.

I got a squeeze noise when turning the wheel on my 2005 525i.The noise doesn't seem to be too bad, but kind of annoying. Does anybody have the similar issue and know the solution for it?

OK-my 2003 525 is at a shop with extensive water damage to the electrical due to rain water seeping into the car somehow and coming up under the back passenger floor. What was your recourse, did BMW pay to repair? I have owned so many Bimmers and never used my garages and never had this happen. PLEASE HELP ME! I NEED INFO

I need to know if anyone has experienced and if BMW NA handled? HELP! When I do general online searches for this I am not getting anywhere! I have owned many bimmers and have never had this happen???
#2382 of 2735 High Mileage Transmission Maintenance
Nov 05, 2009 (11:58 am)
My 2004 530 has 124k miles on it. The service guy at my local dealership said that transmission filter is built-in to the housing and should be replaced at 100k, but I can't find anything written to verify this. Does anyone know if this is true?

I didn't find out HOW to do it, (yet) but the book says it takes 2.9 hours labor to change the filter, so it must, in fact, be a real pain to do. Looks taking off the oil pan isn't all that easy on this car. It also says the FLUID needs replacing at 100K, but doesn't say anything about the filter.
Fluid change is listed at only 1.8 hours, so that must be without removing the oil pan.
The question is, therefore---is a filter change required at 100K or it is a "lifer"?
#2384 of 2735 Question about the oil change and choose oil filter
Nov 05, 2009 (10:51 pm)
I bought 2005 525i recently, condition looks OK to me. I use to do oil change by my own on other cars and would like to do the samething on my 525i, a couple of questions:
1. If I use Mobile synthtic oil, should the interval every one year or 12 thousand miles?
2. Can I use the aftermarket oil filter purchased from other auto shops or better use the one from BWM parts department?

I'd use the dealer's filter or a German filter from an online BMW specialty vendor.
Best thing I can say about oil changes is that if you are going to extend the oil change beyond manufacturer's recommendations, get an oil analysis periodically, and then you KNOW what's going on.
