Anybody have a good direction to go for trying to diagnose why my SMG transmission warning light pops on and off. It appears to only happen with the car is in drive and when you throttle hard between 2 and 3. Never occurred in manual mode.
We took it to the local independent BMW shop and he had no clear ideas on what the issue could be.
Please point me to a reasonable post or any advice would be great.
Find another BMW shop, or a dealership. If the warning comes on, there will be fault codes stored. The codes will tell you why the light comes on. If your shop couldn't figure it out, then he is either inexperienced with the SMG tranny, incompetent, or both. Not trying to discredit him, but I have repaired many SMG cars. They aren't rocket science.
