Sometimes randomly (like once in a week) my 2004 a3 2.0 TDI S-Tronic doesn't pick up speed at all when I reach roughly around 40mph, the car especially struggles to pick up speed 40+. I originally thought it was the MAF so I got this replaced however the car still has the problem. I took it to the mechanic where he scanned the car for any errors and showed me the results. The problem is he's not a specialist on diesels and when i identify the problem he will give the car to another specialist mechanic to get it fixed. I urgently need help from someone who knows what they are talking about to help me identify the problem so my mechanic can tell the specialist to get that error fixed asap. I need to come back to the mechanic on Monday to book an appointment and i have a new job starting Tuesday so urgently need someone's help. I have uploaded pictures of the errors that came back from the diagnostic test, can someone please help me identify which error listed is due to the car not picking up. The forum is the best place I thought to get the help. Regards Juman.
