In Reply to: Comptuer Replacement???!!! posted by Dan Muxie on October 12, 2001 at 11:34:14:
I now have a '94 740IL and I've had to inspect the "electronics", not knowing what I was looking at. However, I'm sure one of those "boxes" I looked at was one or more of the several computers used on that car to control the trans, engine, ABS, etc....
They all appear to be "snap-in" or require a couple of screws removed. If you are confident the computer is your problem and you have access to a 12 year old, buy the computer & pay the kid 5 bucks to put it in or DIY for free.
I defer to the experts who contribute to this forum but I believe replacement of most electronic processing (as opposed to sensor) devices is quite simple & not worth the $$$ the dealer wants for labor.
The caveat: ARE YOU SURE the (probably expensive) computer is the problem? Make sure as where I am (East coast USA) most electronic parts are not retunable.
I wish you all success!
Has anyone ever replaced their computer before? I had some minor work done earlier and shortly thereafter I was down to running on six cylinders as opposed to 12. I took it to another mechanic I knew and he said he reconnected all the vital connections, but it was all to no avail. Does anyone know the price of a computer replacement job? Or what it entails for that matter? Any help/guidance/information would be greatly appreciated.
