Whst external factors have they said it could be? Id definitely be speaking to Audi customer service. And it certainly should not have gone in 5k miles. When I've had issues with main dealers I get a second opinion from another main dealer. Alternatively I'd be getting specialist advice from an independent Audi garage for their opinion.
You could always contact the motoring ombudsman.
My advice would be to get the door card removed and then see what's moving. It could be the speakers, tweeters or electric window regulator all at a guess.
You might need a new unit if the led unit has failed. To find out which bulb you need you could remove the other light unit to see which bulb you need.
You could also get a diagnostic check to see if any fault codes flag up.
Yep it's a phone connector. You might have to replace the center console. Alternatively you could look at an aftermarket armrest from armster or similar.
It would but you'll need the powerfolding mirrors, motors, relays, wiring harnesses etc and it'll need all coding to the car. Autologics have been recommended by others for retrofits on here a couple of times.
If you've bought this from the garage in the last 30 days then you are entitled for a full refund or for them to repair it. It could be the rear light seals or boot seal.
Welcome to the forum you'll find the members on here are a friendly and helpful bunch ☺️ sorry to hear of your recent theft. Onwards and upwards though ☺️
If either cluster doesn't work then it would lead me to think there's a wiring issue. You could have an auto electrician to take a look or get a diagnostic check.
Get it back to the dealer asap! You have 30 days for a full refund. Water could be coming in via the rear wiper. Are you sure it's not the rear washer pipe that's come off inside the boot panel?
My advice would be to get a diagnostic check carried out to see whst fault codes flag up. Also I Know with the S tronic gearboxes if you don't get the oil changes done then this can affect the gear changes. Unsure if this applies to the tiptronic box though.
Also it could be the selector module which is failing.
