Car Forum / BMW Cars / August 200795 bmw 525i.... transmission issues and more
I just bought a 95 BMW 525i with auto tranny. The car does not seem to be shifting and the tranny goes into protection mode. What could the problem be and is there an easy fix for this type of tranny issue. The front right and left rear window does not roll up nor down. I could hear the motor spinning but no movement of the glasss. PLUS the Both front seats are not functional at all. I find it weird that both seats would not be working at the same time, thats why I suspect fuse or relay. DOES ANYONE KNOW WHERE THE RELAY/FUSE FOR THE SEATS ARE LOCATED? > I just bought a 95 BMW 525i with auto tranny. The car does not seem > to be shifting and the tranny goes into protection mode.

First thing to check is the voltage at the gearbox ECU - if this is low for any reason, poor connections, alternator or battery fault etc, one of the first symptoms of this is the gearbox going into limp home mode.

Where is the ECU located. I have been having problem with the electrical charging system. When I remove the lead from the battery while the car is running it shuts off immediately. I had the alternater checked by autozone and its fine.

The volts can go sky high and fry things. Start the car, and check the battery voltage after about 15 minutes running and report what it is.

I checked the voltage and it read 15.26v . like i said the car is not in my town so it takes a while to get to it. let me know what I can try next.

What he meant was start the car run it for 15 minutes, **stop the engine** and report what the voltage is. >> -- >> *If at first you don't succeed, try management * [quoted text clipped - 4 lines] > in my town so it takes a while to get to it. let me know what I can > try next. BTW taking the battery lead off while the engine was running has probably done for a lot of the electronics :-((( > I checked the voltage and it read 15.26v . like i said the car is not > in my town so it takes a while to get to it. let me know what I can > try next. I'd suggest seeing a professional. It really sounds as if you're out of your depth here - and you're causing more damage trying to fix it than there was to start with. 15.26V is WAY too high - with engine running or not. You may have an alternator problem rather than a transmission problem, but asking for help via the net is asking for guesses by people who aren't near your car. See a dealer. That's what I'd suggest you try next. > > You should *never* remove a battery connection with the engine running. > > The volts can go sky high and fry things. > > Start the car, and check the battery voltage after about 15 minutes > > running and report what it is. > I checked the voltage and it read 15.26v . like i said the car is not > in my town so it takes a while to get to it. let me know what I can > try next. Assuming you have an accurate voltmeter that's way out of tolerance. Hopefully when that's rectified by a new regulator the transmission fault will go too. The voltage should stabilise at 13.8v after a few minutes running assuming a decent battery in a good state of charge. Signature*Some people are only alive because it is illegal to kill.
