Had a shop do the smoke test when the car was in for inspection and they found nothing. One thing that was found was the temp sensor in the MAF. It was cleared several times and kept on pointing to that. Got a rebuilt AFM from BMW and put that in. Running better with out the flat spot but still getting this chirping/squeal sound when under load when the car is not fully warmed up. Any other Suggestions?? __________________
