I have an Audi A3 1.4 TFSI (2013), 95,000 miles. Just this past weekend I was driving up the motorway and had what felt like a loss of power and the engine management light came on. There wasn’t complete loss of power. I pulled over on the hard shoulder and waited for the AA. The AA had me drive to the next junction to come off the motorway. At speeds of around 50 mph, the car didn’t feel any different to drive. However, when I had to slow down for traffic lights at a roundabout the car was very jumpy and jittery. Anyways, it’s been ok the local garage where they have run diagnostics. I’ve attached a copy of the report. The guy in the garage has done a compression test and cylinder 2&4 both had problems. He has said he’s seen this before on TFSI engines and that the engine needs to be stripped down so he can determine the problem. He has said from experience it could be a valve or the piston injector, but that he can’t be sure unless he takes the engine apart.
Has anyone else experienced a problem like this and determined the what the problem is or the cause of it?
I currently have the car with a family friend who is a retired mechanic, hoping we can fix the problem without spending thousands of pounds in a garage.
if anyone has any advice or any idea what it could be, it would be greatly appreciated!
thanks!
