khaledalx Posted April 11, 2013 Report Share Posted April 11, 2013 Hi I just bought 2004 M3 SMG. About 100k miles. 1-Drove fine for about 1,000 miles (highway). 1.1 when i drove in a traffic jam I noticed a "grinding" noise from under the car with the SMG light illuminated. 2-I Turned off car, It did not come back on after restart. 3-Drove car about 10 miles and the SMG light came on again. 4-Then it was not shifting normally. Would drop into 0 when coming to a stop. 5-Sometimes will automatically go back into 0 gear, other times I had to manually shift it back to gear. Grinding noise is more noticeable. 6-One time would not shift past 2nd. 7-Let it cool for about 1 hour. Was able to drive for about 10 miles with no issue, no SMG light. Grinding still noticeable however. 2 Videos attached Please help me diagnosing this issue Link to comment Share on other sites More sharing options...
mazin Posted April 20, 2013 Report Share Posted April 20, 2013 If you haven't got the computer diagnostic done, its good to get that to see what problem is logged in car computer. That should be enough to give heads up and get started with some educated guess work. Link to comment Share on other sites More sharing options...

Its not Semi Automatic...Its identical to the Manual transmission except that the clutch is controlled by the computer via the SMG pump. Link to comment Share on other sites More sharing options...
