This is my first post, so bare with me.
I have (well my wife does) a 316i auto compact 94 and we seem to have an intermittent problem with Auto box warning light. It comes on for no particular reason (im sure there is a reason, but i cant find it )and then normally goes out. While the light is on, the box is in limp home mode, and only 3rd gear is available. Disconneting the battery normally puts the light out for quite a few days, sometimes even weeks.
We have sent it to the good old BMW dealer with no success. No fault codes, nothing. I have changed the fluid and filter and this has had no affect either.
I think the next thing to try would be to replace the sensor, iassume there is one?? What do you guys think?
