It might be a faulty sensor, but it's more likely a blocked DPF in need of a clean. A detailed scan on a professionally reader should provide the answer.

Better to buy a proper light than to try to bodge up a cheap defective light by changing the code.

Unfortunately sidewall damage is more serious than tread damage, and means a new tyre is needed.

One more fairly remote possibility occurs to me. Has the car been in a crash that needed the body to be straightened in a jig? If that is not done properly it can leave the body slightly twisted such that the doors appear to close fully but the rubber seals are not crushed enough to be water proof.

Do let us know the outcome. If the passenger door wiring proves to be damaged, look in the driver's door as well in case that is starting to fail.

It would be worth inspecting the wiring in the rubber bellows between door and pillar because it tends to fracture and cause problems with the locks and windows. If the mirror wiring runs through that same bellows it may be damaged. You will need to remove the door card for access.

Unless you code the battery to the car there is a possibility it will be damaged by over charging. If you can't afford a decent scanner, get the coding done by a professional. It will surely be cheaper than buying a new battery every few months. By the way what is a noid light? I've not heard of them.

Some details would be useful Jake. Which engine? What fuel? How many miles on the clock? Has it been modified?

Did the comments above help Lewis? I know you have seen them.

Suspect worn rubber bushes.

That's probably the best you can hope for in the circumstances. It may even prompt Audi into action.

You're welcome Padraic. If you want to pursue the oil and diesel consumption problem it would be worth starting a new topic.

When the reservoir level rises after removing the filler cap it usually indicates an air lock in the cooling system. That would also fit with inadequate cabin heating. I don't know specifically about your engine but some can be a devil to remove air. Suction at the filler neck is often effective at expanding the air up to the reservoir.

Most likely its a worn CV joint. Less likely its a worn rubber bush in the suspension or a wheel bearing. I suggest you get it inspected at an Audi dealer or preferably an independant VAG specialist.

The topic of wet footwells comes up from time to time so it would be worth looking through forum history for ideas. A wet seatbelt is something I have not heard of until now. There must be a leak fairly high on the body for that to happen. Are the door and windows seals intact? Are the doors and windows in fact fully closed?

I do not disagree.

It seems so. You implied that the charge rate dropped suddenly at midnight on a certain date, which makes me wonder if a schedule in the car had expired, or your electricity supplier had changed something if it controls the times of charging.

Water ingress to electrical connections can be very difficult to dry thoroughly. Try WD40 which is designed to displace water (hence the WD in its name,) or preferably isopropanol and allow to dry for a day or two with good ventilation. It's possible water has got into other electronic components or connectors which may take a long time to trace. At the risk of stating the obvious please don't drive through floods. The A6 is a car not a boat.

What you wrote on May 21, 2024 was "Will keep you posted as mine is still at the early stages of reset and adaption". All too often people ask questions of the forum but never return to help others with the outcome of their problem.

I'm surprised there is no pre-ignition with that much petrol in the diesel, but if the engine runs well, so be it. Do let us know the outcome.

Please do Nick, because Graham couldn't be bothered to let us know of his outcome and we'd like to know.

Thanks Mark. That's a big difference in final drive ratios, 2.917 versus 3.450.

Any modification could be used as an excuse to void a warranty, whether it was justified or not.

Unfortunately Bogdan, Mark never returned to the forum to update us as he promised. You might try a PM directly to him.

2000 rpm at 70 mph does not strike me as abnormal. Bear in mind the two engines may be similar but the gearing can be very different.
