I guess the second hand one could be faulty? As you say it should just be plug a d play.

As cliff has suggested I'd recommend a diagnostic check to see if any fault codes flag up. Otherwise we're guessing. But could be issue with maf sensor, lambda sensor etc.

Have you traced it to see where it goes?

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 looks a lovely car.

Glad you got sorted 🙂

This should go back to main dealer for diagnostic check to see if any fault codes flag up. In the handbook it should tell.yiu how to do a system reset on it. Might be worth trying that also.

Engine code should be in the inside cover of the service book. I know it is on my older A6

I wonder if it's a problem with the dpf.

What about any tyres from hankook?

Glad you got sorted 🙂

Quite a few on eBay. https://www.ebay.co.uk/itm/355110793527?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=Qn30XPa8QES&sssrc=4429486&ssuid=IE07kO4STZy&var=&widget_ver=artemis&media=COPY VW Tiguan or Skoda models are the same.

I appreciate this is for an A6 c8 but I think the process is the same: https://www.audiworld.com/forums/a6-c8-platform-discussion-229/disabling-auto-dimming-mirror-feature-3007601/

I know it affects q5 models too. Is it worth you speaking to Audi directly?

As it's a 2.5tdi it could be a leaking egr. These have been known to leak oil into the coolant system.

Not one I recognise

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 Glad you got the problem sorted. I'd recommend you try eBay for the mirror.

I'd recommend a diagnostic check to see if any fault codes flag up. Could be an issue with the turbo, maf, gearbox module etc.

Could it be an issue with the mad sensor, cam sensor or injector

If battery is in engine bay then the drains for the battery location could be blocked. First thing I'd do is remove the skuttle panel near the bulkhead to see if you can see any trapped leaves etc. It's the black plastic with vents either side. https://www.audi-sport.net/xf/threads/342829/

I'd recommend you try eBay including international sellers. Just put in the Audi and the gearbox code to see what comes up.

Keep us posted on how you get on. I fail to see how a particular paint colour would affect the radar and sensors.

You're welcome, glad you got sorted 🙂

No probs
