Audi TT Ignition Coil Issues Causing Multiple Problems

I had a very similar issue with my 2014 Audi TTS. As someone with some car repair experience, I can relate to these engine hesitation symptoms. My car showed identical signs, rough running, stalling at idle, and jerking during acceleration. The check engine light was also illuminated. After experiencing this for a few days, I took it to a workshop where they ran vehicle diagnostics. The root cause turned out to be a loose connection in the wiring harness leading to one of the ignition coils. The cable had worn through and was making intermittent contact. The workshop did a thorough check of the ignition system and found this issue rather quickly. The repair involved replacing the damaged wiring and ensuring proper connection to the ignition coil. Total cost was 95 Euro and the car has been running perfectly since then. Before suggesting specific solutions, could you share: Current mileage on your TT? Have you noticed any other warning lights? Does the problem occur more when the engine is cold or warm? Have you had any recent work done on the ignition system? This information would help determine if your issue matches what I experienced or if there might be other factors to consider.

Just had my car serviced at 130749 KM a month ago. Your issue sounds exactly like what happened to me. The rough running and stalling turned out to be caused by worn spark plugs and one bad ignition coil. Vehicle diagnostics confirmed multiple misfires related to cylinder 2. The engine hesitation went away immediately after replacing both components. I would suggest having all spark plugs replaced as a set even if only one ignition coil is bad. The total repair cost was around 280 Euro parts and labor, but the car runs like new now. A proper check engine light scan would help pinpoint which cylinder is causing the issue before replacing parts.

Thanks for the update on your TT repair. Your experience matches what I found with my TTS, coil failure often shows up alongside worn spark plugs. After my initial wiring fix, I actually ended up replacing all ignition coils and spark plugs preventively since they were original parts with similar mileage. The vehicle diagnostics in these cases are really crucial. While my initial problem was the wiring connection, the comprehensive scan also showed early signs of coil pack deterioration in cylinder 3, which could have led to engine hesitation issues down the line. Quick tip for others reading: When you notice these symptoms (rough running, stalling, check engine light), get a proper diagnostic scan right away. Waiting can lead to more severe engine performance issues and potentially damage other components. The repair cost is usually reasonable when caught early, similar to what you paid at 280 Euro. The immediate improvement you experienced after the repair is typical when dealing with ignition coil and spark plug issues. Would be interested to hear how the car performs after a few thousand kilometers with the new parts.

Thanks for sharing those detailed repair experiences. All symptoms you both described match my situation perfectly. The car has 145000 KM, and no other warning lights are present besides the check engine light. The engine hesitation and rough running seem worse when the engine is cold, especially during the first 10 minutes of driving. I just had both the ignition coils and spark plugs replaced for 295 Euro total. The vehicle diagnostics confirmed multiple misfires in cylinder 3, exactly matching what others experienced. The coil failure was causing the engine stalling and poor performance issues. After the repair, the check engine light cleared and the car runs perfectly smooth again. No more jerking during acceleration or rough idle. This seems to be a common wear item on these engines, so I plan to keep a closer eye on the ignition system maintenance going forward. Really appreciate everyone sharing their experiences, helped confirm I was on the right track with suspecting the ignition coils as the culprit.
