#2222 of 2734 bmw 525i hvac and sensor issues
Dec 13, 2008 (9:17 am)
I have a 2001 525i with 165k miles on it. i'm currently having several issues i need some education on.
first, my heater controls have become "possessed" regardless of what temp i select on either heat or ac, the fan motor blows erratically, switching from fast to slow, back to fast in a matter of seconds and just keeps doing that the entire time. this happens if i have it on auto, or floor, etc. if i try to manually control the fan with the + or - control it does no good. it is so bad i can't even use the heat
second, my windshield wipers will only go up, get stuck at the top and then i hear a "wurrrr" sound from under the windshield and they stop. I can give them a push with my hand to get them back down, and they seem to be free and nothing blocking them, and when i turn them on and manually help them along with my hand nothing seems to be binding, but if i let them go they'll stop in the same place every time.
fianally, my check engine light is on again, and the code is coming up cam shaft position sensor"B". This will be my third time replacing this same sensor, they only seem to last about 30k miles before they fail. I'm using a genuine bmw replacement partany idea what wold keep causing this to fail?
i could really use some good advice as finances are tight and i really can't afford another $2000 bmw service repair bill.

Your first issue is a Final Stage Unit. I had mine replaced last Wednesday when I bought a new battery. The part was $102 and an hour of labor covered both.
I cannot help you on your other issues.

Like 530i said; your HVAC problem is the FSU. It's a dead easy DIY. As for the wipers, bsst case is a loose nut in the linkage. Worst case is that the wiper gearbox-or "wiper console" as BMW calls it-is DOA. The part lists for $240. As for the cam sensors, you got me. They DO fail, but not nearly as often as they have in your case. Have you joined the BMW Car Club yet? You'll find many shops offer BMW CCA part and/or labor discounts and you'll have access to club technical advisors as well.

Thank you for this info. I have the same problem with my 2001 525iT. When I bought mine the previous owner told me that he had just replaced the fan unit at the tune of $700.00. Reading this, he may have been taken for a ride.
When you say dead easy DIY, where do I find the unit and is there any info (web site?) that explains the installation procedure?
PS Same for the rear windshield wiper, I can't find any info about how to replace the arm.

Here's an excellent final stage unit DIY.
I've never had to deal with a rear wiper on a touring; perhaps this parts diagram will be of some help.

I am currently looking to purchase a 05 or 06 5 series, either the 6or 8 cyl. I am wondering about the reliability of the cars and I'm looking for any and all experiences, opinions, and imput.

has there been any technical issues with navigation? Im looking at a CPO 2007 530i (29K miles) that has nav, and all the packages (sports, premium, cold, and one more can't remember) car is beautiful asking $34,900 for it, with negotation some wiggle room. I just want to be sure I'm not looking for a problem with the navigation which I don't even care about, but the vehicle has it. Car is really loaded, would hate to pass it up.
Also another one 2007 530xi, 18K miles, warranty expires Apr 2014. Asking $36,900 dealer won't budge. That's another 2 grand, but warranty goes longer. Am torn, don't know what to do. I'm leaning toward the $34,900 one, has more. Dealer says his 530xi is competitive in price. I could care less about all wheel drive.
That extended warranty is tempting however.

Living in Germany, I just bought a 1996 520i Touring with 200,000 kilometers (German specs). It's idling at 1,000 rpm, hovering over 4,000 rpm at 35 mph in third gear, and redlining just above 6,000 rpm in fifth at 80mph. But, it's not running hot and it doesn't feel or sound like the engine is straining. The fuel gauge is broken (reading empty at all times) but the speedometer and temperature gauges seem to be operating normally. This is my first BMW (when in Germany....) so I'm not sure if they typically run at higher rpms, if maybe the tachometer is malfunctioning, if there's some kind of "adjustment" I can make, or if it's simply a mechanical problem. It's getting a tune-up in a couple of weeks, but should I be concerned about driving it on the autobahn until then?
Any comments are greatly appreciated!
