#796 of 832 Re: Concerns with maintenance of a 2009 BMW 750LI CPO [momentum28]

Momentum - are you looking at an extended warranty or a CPO car that comes with one? Assuming you are more concerned about the price of repairs versus service costs, most extended plans outside of CPO have several levels of coverage. I priced a few out as I recently bought a 2008, and electrical components may be covered completely, partly, or not at all depending on the plan. Not surprisingly, the plans with the most complete coverage cost more. For example, the plan from the BMW dealer only covered the NAV and audio system if you bought the most inclusive plan.
You need to read the complete coverage of the plan before deciding which plan, if any, is worth the money. Some of the plans might specify what they *don't* cover, which is helpful. Most plans offer coverage levels labeled with names like "silver", "gold" and "platinum", with ascending prices, of course.
If you buy the CPO car examine the coverage (in print) to make sure you know what you're getting. A 7-series has a LOT of electrical components and is complex, so on the average you're more likely to have electrical issues sometime compared to, say, a simpler car such as a Toyota Yaris or similar car with less electrical components. That doesn't mean you'll necessarily have a lot of problems, but the possibility is greater.

I'm beginning to have a few on my 2008 750i. It's still in warranty but before I take it to the dealer I'd like to ask if anyone else has seen this "behavior" on others so I might possibly save time with multiple trips and trial-and-error diagnosing there.
For the first few months I've owned it no issues, but recently I noticed in the mornings that the soft-close doors weren't working. And at the same time the CD changer had reverted to the FM radio tuner when I started the car, even though I had turned it off the previous day with the changer engaged. (It's in a garage so I ruled out temperature) Once I started the car the soft-close doors worked fine. The problem is intermittent, but this AM the interior lights were ALL off when I opened the door, the soft-close feature didn't work, and the radio had reset again. When I saw the lights not working I thought the battery might be dead, but the car started fine.
And oh by the way, I've had a problem with the driver's window not moving down. At first I thought it was the switch or maybe the motor, but after about 5 episodes of this I think I managed to get it working AFTER moving one of the other windows first, so I suspect some system the window may be tied to.
My car appears to be more confused than me. Any observations?

follow-up: took to Indy and it took 3 guys to align the bolt and push through. Maybe an aberration? thanks for the reply.

Are you the original owner? I've heard of this kind of problem when a car was in a previous accident. The unibody gets every so slightly torqued.

You are right about the accident on front passenger side as it may have caused the unibody problem. Good catch.

2001 740i with recent new ignition coils, fuel filter, plugs, BG44K fuel system cleaner, and CPS sensors about 2 years ago. Checked for air pressure leaks on hoses, and lower small hose from the MAF boot on right side of boot was split at the connection point. I put duct tape around it to see if it would help before replacing. Problem still there. Could this cause my rough idle after starting and warming up car to where initial high idle of 1000 rpms returns down to 600 rpm and then fluctuates from 600 to 650 and car front shakes alittle? What is on the other side of this small hose that it connects to?

Well if you have had one vacuum leaks there could be others, so yeah, vacuum leaks create all kinds of air/fuel mixture issues.

Could you tell me where the other end of the connection goes from that MAF small hose? I could send a picture if you're not sure what I'm referring to... thanks.

No, not without a car in front of me. Have you pulled any trouble codes?

trouble codes have all the markings of a vacume leak; misfires, CPS, and maybe one other; I have noted a web posting on your site that had a similar problem with same codes and they leaned towards a vacume leak. I sprayed brake cleaner on MAF fitting and it did seem to change the idle speed, that is why I was wondering if you knew the purpose of the 2 connections off the right side of the MAF as you are facing it. I've been to two Indys already and trying to avoid going back to them or to a third as I've already gone through plugs, ignition coils (my call) fuel injector cleaner, and I am skeptical that its a CPS problem. Is there a way to attach a picture to my post?">
