Just received a letter today from BMW corporate acknowledging problems with high pressure fuel pump (HPFP) problems on 2008/2009 535i models, and as such is extending the warranty on the HPFP from the normal 4 years/50,000 miles to 10 years/120,000 miles, whichever comes first. I'm saving that letter for any unfortunate future reference.
My HPFP went at 17,000 miles on my 2009 535i x-drive. Dealer knew immediately the cause, though did not acknowledge any known problem when I questioned them on it. Surprise, surprise. Otherwise, the car has been problem-free and one sweet ride.
I wonder if the recent Toyota debacle has given the entire auto industry a wake-up call. I certainly hope so for the sake of both the industry and us consumers. The cost of recalls and extended warranties pale in comparison to the cost of a damaged brand.

wow after reading about these 535i problems, I'm so glad I didn't go with the one I saw at Bridgeport BMW (CT) last year! Something just told me to not go with a new model (turbos).........my instincts were right. Anyway..........have a beautiful 2007 530i, just had it serviced under the warranty 30K......came through with flying colors, didn't cost me a CENT. Service tech said see ya next year, but I'm wondering, an oil change every 15K miles, does that sound correct? It just seems like a lot of miles to go between oil changes. Guys thanks. I've learned so much from these boards.

There are lots of opinions on the proper oil change frequency. I change it every 8,000 miles in my wife's 2004 X3 2.5, primarily because used oil analysis indicates that the oil's additive package is almost depleted by that mileage. Other have good luck with the 15,000 mile interval, but not me...

It depends on the type of driving you do. Lots of cold starts and city driving and 15K might be too long. Mostly highway, it might be okay. Also depends on the oil they use (Mobil 1?) and the volume. I have an Infiniti that I've been using synthetic in and having the oil analyzed. 11K on my engine is about near the end of useful protection with a 60/40 mix of highway/city. Their service interval is 3750miles, but analysis shows that that is way overkill unless it was hot/dusty/short severe service.

I just never felt right about a 15,000 mile interval, seems way too long, for a high compression engine. For new cars under warranty that offer free maintenance, like BMW, if you say change the oil at 15,000 instead of say 7,500 or 10,000, the cost savings are obvious for the company and the car is out of warranty most likely before any major damage is evident. My gut tells me that a 7,500 mile interval with synthetic oil is reasonable and that is what I have been doing. Valvoline does it for about $90 with the extra oil required.

The one sure way to tell is to spend the $25 or so and send in a sample of the oil at your 7500 mile interval to see how much life is left in it. Then, you have a valid assessment of the life left in the oil. If it saves an extra $90 oil change, and confirms the oil's good, or bad, then you have a basis for discussion with the dealer about what needs to happen.
Many of the synthetic oil companies offer their own warranty if you use their oil and follow their recommendations - Mobil 1's recommendation is 12000 miles or one year, whichever comes first.
A car that is designed for extended oil changes usually has more oil in the sump than a more 'normal' engine. This means a larger reservoir of addatives and often, a longer change interval.

My 2006 BMW 525i keeps giving me warning "low coolant" about a week after I filled it up. I took it to a local shop. The technician tested it (blowing air to the coolant openning) and he found no leaks at all on the tubes and radiator, although we saw water leaks to the bottom tray. He then open the engine oil cap and said the water must have leaked to the engine because the oil color has changed to light brown. He susggested to take it to the dealer for further testing and repair. My questions are:
1) Was his diagnostic correct?
2) If he knows what's wrong, why didn't he accept the job to fix it?
3) How big a job to repair the problem when coolant mixing engine oil?
4) What shops (in Orange County, CA) are good to repair the car besides the dealer to reduce the cost?

This doesn't sound like a diagnosis at all, but rather a guess based on an oil cap??
There are very conclusive ways to test for head gasket failure or even oil separator (BMW's fancy PCV valve) problems, so yeah, you need to go somewhere that knows about BMWs.
If in fact you have water + oil extensively distributed throughout your engine, you'd better pour yourself a stiff drink. I think not, but you need to have this properly diagnosed and stop driving the car until you do.

I'll bet it's either the water pump, t-stat housing, or the expansion tank.

I have a very similar issue with lights coming on and going off intermittently. Also have my horn and radio sometime not work, then start to work again.
I'm assuming it's the computer module but curious as to what you found when you had it serviced.
