I have a 2002 BAM S3, over the last couple of months the Lambda sensor in the downpipe seems to be removing itself! First time I took it to a mate and he diagnosed it as many other garages were saying it was a crack in the downpipe! Whilst I was with him he managed to get it back in place and tightened up, result I thought! Now 3 months down the line, was going round a roundabout last night and it has come out again.
Has anyone else experienced this problem and is there anyway I can get some form of locktite to hold it in place?
Any help very much appreciated!
