I have a problem with my Lock System, It doesn't work correctly, If I drive the car all day
It works the first 3 to 4 hrs, and when the weather is really hot it does not work at all,
when It doesn't work I can't open all 4 doors with the key only the driver side will open
manually, but the trunk works all the time, don't know what is cousing that problem in my car,

Any Ideas??

Thank you!!

Ernest

Hi. Probably GM5 module faulty, common fault on the E46. Google GM5 Module. Jim

same problems with 2001 330i. sometimes it works, sometimes it doesn't in hot weather. I just live with the infrequent problem, resetting the locking mechanism by clicking it lock, unlock, unlock, lock.
