Hello, all. I have a '95 BMW 740i with 182,000 miles. I love the car. However, it now thinks I am trying to steal it, so the immobilization system is disabling the starter. I know this because I can remove fuse 55 (a good fuse) located in the trunk and the car will then start normally. However, this fuse disables alot of other things including windshield wipers, power windows, power door locks, variable power steering boost, etc. My biceps are getting a workout!
The stealer replaced the general module 2 years ago, when the same thing happened. Now the dealer wants to replace it again! Is this programmed into the general modules or what? lol. He throws in words like double locked and central locking, etc. Is there anyway to RESYNC or RESET this thing (perhaps the EWS? is that what it is called?). I would like to try that first.
Second, I kept the old general module. I bet is if I clean the contacts, it will work fine. Does anyone know a good contact cleaner? What is the replacement procedure for the general module? Do I disconnect the battery first? Any caveats?
Third, I think one of the theft sensors is the main culprit, and it eventually throws off the general module. Any comments on how to test that theory.
Lastly, can I temporarily totally disable theft immobilization or the alarm system or both, so I can put fuse 55 back in and get some power back? Thank you all.
