#722 of 2735 Weird problem with 1998 BMW 528i
Jul 22, 2004 (10:43 am)
For the past year and a half, I've been having a strange, intermittent problem with my car. Every now and then, it will start acting up for 1-3 days, during which, the tachometer will get stuck up around 3 or 4 rpm and my car will feel as though it's locking up. The car also makes a loud revving noise when this happens. I will take my foot off of the gas, but nothing happens. I have to hit the brakes hard in order to release the car. Sometimes when this problem is happening, the tachometer will jump up to 3 or 4 rpms as soon as I turn on the engine. Other times it just happens as I'm driving, sometimes at 30-40 mph, other times at 60-70 mph. The car will act up for a day or so and then may be fine for the next few months. Then one day, it will happen again. I've taken the car in to two different BMW dealerships and they can't find anything wrong. They say the transmission is fine and that the onboard computer isn't reporting any problems. However, I know I'm not crazy because I've had plenty of passengers in the car with me who have experienced this. I am at a loss as to what could be causing this and what I can do about it. Any help or advice would be greatly appreciated. -RyanM

The poor A/C performance in city traffic was indeed a faulty auxiliary fan. Fixed under warranty.

Hmmm, I don't know why, but my gut tells me that you may have a problem with your cruise control. I don't know if it has a separate circuit breaker/fuse, but if it does, you might want to pull the breaker/fuse to see if the problem is eliminated.

DSP = Digital Signal Processing.
But you go one to say that it "enhances it through analog signal processing". Am I missing something here?

I don't have a real solution for your problem, but an option to seek out. I have run into similar intermittent problems and found that in most cases dealers are worthless. With all of the electrical systems, if the computer does not detect a problem, they don't know how to trouble shoot. Further, the good mechanics usually leave the dealers and go out on their own. I would seek out an independent BMW mechanic that could possibly do some real trouble shooting AND try the suggestions (like shipo recommended). You may have to eliminate some options to get to the real problem.

I hear what you're saying about the software muddog. I just brought in my month old 545 for something else (not anything wrong) and there were two recalls, and one was the software upgrade. They gave my a 325i loaner and I felt the same way without active steering. I went real wide around several turns!
#729 of 2735 Tire blow out
Jul 26, 2004 (6:52 am)
About 16 days ago, I purchased a 2003 CPO'd 525i with about 12K miles. While driving it yesterday morning, I suddenly had a tire blowout( not a flat) on my front left passenger side. The tire blew without any warning. The car has the original factory tires. Was there any recall on these tires? Has anyone had this experience? I'm going to call the dealer today to discuss. Any advice would be appreciated!
#730 of 2735 Low Mile CPO and Tire Blow Out
Jul 26, 2004 (11:32 am)
tam2k... BMW's CPO program does have some standards in regard to the tires and tire wear. You should ask to see the dealer's data on these criteria, esp. measured tread wear. And see if they have any data regarding whether they properly inflated the tires. Also, ask if these were the original tires.
What make/model/size tire was it?
You don't discuss how fast you were travelling, what sort of load (passengers & luggage) you were carrying, outside temperatures, road surface conditionss, tire inflation info, etc. which might be related to your situation.
Most importantly, what was the diagnosed cause? Was it punctured at all by anything? Had it just hit a big pothole at speed? Were you driving long distances at higher speeds in high heat?

Here are some additional details.
The tires are Michelin Radial XSE 225/55R 16 95H M+S.
We were on the interstate at around 10 am about to begin a 200 mile trip. There were 3 people in the car and a couple of medium size bags in the trunk. We didn't hit any kind of pothole or anything in the road. We were riding along talking and then we heard a loud explosion sound. Then the steering wheel shook and we immediately pulled off to the side of the road. That's when I saw the tire had exploded around the rim of the tire.
I was told that these were the original tires when I bought the car.
I'm going to take the tire for someone to review today.
