Cars do not repair themselves, so be prepared for something similar to happen again.

Hello all, New member, glad to be here. Two weeks ago I treated myself to a low mileage, 2020 A7, which I love. In 40 years driving i have owned and driven a large variety of vehicles including two previous Audi's (A4 Quattro, A5) quite a few vans, motorbikes and most recently a 2.8 Hilux pickup. I don't recall ever being so 'chuffed' with any car I have owned. I love everything about it, the styling, comfort, tech and pure driveability of this A7.

Have you checked the pollen filter housing? When was the AC system last regasssed? Is there any water in the wheel well? Is there condensation on the inside of the vehicle when you get into it in the morning?

Hi Steve multiple owners or high milage may well explain, that and its age when you consider that the suggested change intervals are 60k, they don't struggle to start in the cold mostly because of the insane pressure from the fuel rail. Steve.

Hi its the oil level sensor in the sump going south, they are pretty useless but the upside is they are fairly cheap and easy to replace, dont buy the Audi gold plated version as its made by Febi and their aftermarket version is less than half price, the whole sensor is calibrated by a bonnet switch on the slam panel so check the wiring up to that just to be sure but its most likely the electrics which are exposed to boiling oil. Steve.

Got it fixed. Don't ask me what was wrong with it. I simply disconneceted the battery to check the wiring loom the guy on this forum was talking about, then reconnected it after seeing that nothing wrong with it and it was all working. Got esp light and power steering light but just did a full lock on both sides with the steering wheel and they went away. Thanks for the time you took to reply cliffcoggin, and also anyone else reading this topic. Hope your fix will be as simple as mine 🙂.

Glad it runs fine 🙂 the symptoms of failing glow plugs is that the car will struggle to start in cold mornings.

Unless you have a high quality code reader I suggest you ignore it and get the car scanned professionally. Most cheap domestic code readers are so misleading as to be worthless. There are a few possible causes for your problem that include a defective battery, a faulty instrument panel, and a faulty ECU amongst others, but you will not know without testing.

Could well be the glow plugs but I do find it odd in some ways they've all gone simultaneously.
