Afternoon all,

My 2016 Superb started a slight shudder when driving normally and has subsequently got worse. Now when it shudders various dash lights come on, systems say not functions, ACC, Park Assist, Tyre Pressure Warning etc and the car goes into limp mode. Had to pull over, with the car off and then back on to clear the issue. Was infrequent but became regular.

Went to my local VAG specialist who checked the fault codes and said the code related to wires down the side of the engine may be causing a short, which he checked and confirmed was ok. Had a really noisy grumbling mass clutch flywheel, has done 128K, garage said could be the speed sensor on the clutch assembly causing issues, so suggested a new clutch pack.

New clutch pack fitted this week, but fault remains. Sat idling this week, engine switched off, then back on, did this twice. Car shudder and lights on twice today, cleared by swiping off and on.

Suspect a return visit to the garage, but think they may be struggling.

Anyone experienced this before, any ideas or suggestions on what may be the cause would be welcomed.

Many thanks in advance

Tony

Not sure on the shudder but that collection of lights usually means a communication issue between control modules, which is commonly caused by low battery voltage. How new is the battery?
