Ahhh damn that doesn’t fill me with hope as piston rings are an engine tear down, thanks mate appreciate it will get compression tested and pray

Hi it should start with the right cranking voltage, check the starter motor and battery. Steve.

Hi its got sod all to do with the tank sensors its the manky gauge every car I have ever come across with that system, Peugeot, Citroen, Dacia its a cheap and nasty bit of kit, you can either get the dealer to recalibrate it, if they can, or ask them where to get virtual fuel. Steve.

Hi any warning light even if appears and disappears warrants investigation as the way the software works on Audis is it monitors faults and severity until they come up a maximum of ten times this then defeats the unlearning counter therefore it becomes a permanent code and possibly limp mode, now that you have announced its petrol I would definitely check the injectors but I do suspect if it smokes when accelerating hard it may be worn piston rings, get a compression test done to rule that out. Steve.

Audi parts dept do not have a part number for the 2026 top cover as they are not made. If you have open threaded holes in your engine rocker cover that match the earlier 35tfsi then you can get a top cover from the earlier model. You will need to get the mounting pins as well.
