View Full Version : 1996 M3 Evolution - SMG failure?
11-26-2008, 09:04 AM
I have a 1996 M3 Evolution SMG with 87,000 miles on the clock. I took it out the other day and when I tried to change from 2nd to 3rd, there was a long pause (about 5 seconds) before it changed into 3rd. When I tried to change from 3rd into 4th it would not change and just stayed in 3rd. I pulled over into a layby and turned the engine off. When I turned the ignition back on, the dashboard displays E 3 with an exclamation mark and I can not start the vehicle (presumably because it is not in neutral). Can anyone offer any advice? Does this mean the SMG pump has failed?
If it is the SMG pump, does anybody know roughly how much these cost secondhand and new, and how much to fit at a BMW independant specialist?

This problem might also be caused by failure of the clutch slave cylinder - not cheap either, but better than the pump and fast to swap out.

Ok, thank you. Does anybody know a way I could get the car into neutral so that i can move it from it's current location (because it is vunerable where it is at the moment)?

You can let it warm up, slowly rev the engine to see if you get the SMG to engage, and then flip it back to neutral. Otherwise, I think you'll have to tow it.

Ignore my p[revious post - my fingers were faster than my brain. If you can't get it into neutral, you can't start it. Duh!!
I think you'll have to tow it.

lol think again - can't tow it as it is in gear... Or did you mean tow it to bump start it (as it is already in 3rd gear)? Obviously I'm assuming there is no 'PARK' or anything like that on the SMG gearbox?
