I have a 2006 2.0TFSI , It was carbon cleaned and had a new cam follower and S3 injectors fitted NEW. Then it was tuned to Stage 2. Then a month later develops a miss fire under load. Spoke to the garage who did the injectors and they were adamant the injectors dont fail. I spent months trying to fix it. If u drove like a granny it was fine. I changed, spark plugs, coil packs, N75 valve, Diverter valve, PCV Evap valve, in tank fuel pump, coils again, still had the problem. Got my local garage to swap the injectors from cyl 1 to cyl 2...misfire jumped to cyl 2. I then had to go back to the place who did the injectors and get em to replace the one in cyl 2. They testes it and it was only flowing 1mm less than the others, wiring was fine, but something was not right, they changed it and my car has been fine now. 187k currently.

Thanks for watching glad you got it sorted eventually! Glad this one wasn't an injector!
Injectors with them codes it’s a TFSI i wouldn’t have even popped the bonnet that night and spoke to the owner
Thanks for watching luckily it was just the coil in this case!
Cyl 1 injector. - im guessing, im 30 secs in 😂
Close! Correct Cylinder atleast!
