I've just gotten this 2001 BMW 540i and know it has been in good shape and has been taken good care of before I purchased it. (It has about 64,000 miles and a V8 engine.) But for the last few weeks, tons of things have gone wrong and I've spent over $2,000 in repairs. I've had the oil level sensor replaced, the engine-cooling thermostat replaced (that, at least, was under a parts warranty), one of the oxygen sensors replaced, and the alternator and battery replaced. It has been devastating.
One of the repair trips was to the dealer, and they recommended that my mass air flow sensor needed to be replaced, but there were numerous problems with my visit there and I felt that they weren't being straightforward with me, so I had minimal work done there and took it to my own mechanic, who didn't think the MAF sensor needed to be replaced.
Yesterday, I got in the car and none of the gauges on the car would work. The electrical system seemed shot, as the blinkers wouldn't work properly, the digital clock on the dash had stopped, the air conditioner was pulsing, etc. So I brought the car home and am trying to figure out what to do next. Does this sound like a problem with the mass air flow sensor? If so, how much does this typically cost to replace? Are there other likely causes for these symptoms?
Thank you very much for any ideas! : D
