Hi Guys, Not used the vagcom cable much yet but heres my first log. The problem is im loosing boost about 3500rpm. sometimes completely andother times like for this log it flutters kinda. like its not sure what itdoing boosting or releasing. Ive read it can be the N75 valve for this kindaproblem but wondering if any of you might be able to have a look and see whatyou think. I know the MAF reading are low but the problems happen with orwithout it plugged in. http://i1108.photobucket.com/albums/h419/finnmc1/S3 logs/S3Log.png Cheers guys.
