You might find another one could be coded as long as the numbers match. The letter should specify the model variants as all parts are slightly tweaked through the production run.
Alternatively you could look at an aftermarket set up
Wouldn't say a vibration to be normal. How long have you had the car?
Might be worth you getting a second opinion.
Could it be a gearbox mount I wonder?
Yep it can be done, you'll need the upgraded stalks. Here's a YouTube video which might help:
Also here's a guide to costings:

Was this a plugin map or one done on a rolling road?
If it was the former I'd recommend resetting the ECU to original factory settings to see if the issue goes away.
The problem with remaps is that it can put extra strain on already worn components.
I agree with Gareth, it's extreme to need to change the whole roof for a rear window that's coming loose. It often just needs rebonding. I'm sure I've done a guide on it on the forum somewhere, I'll see if I can find it.
Was the previous work done by Audi? If so Id like to think there might be some good will. My dad had an 8v 1.6tdi and it blew a turbo at less than 30k.
I'd have said heater matrix as the first port of call. Have you got any wet carpets which could be caused by a leaking matrix?
Definitely inspect the expansion tank as these can split especially around where they're joined together. I had that on a works van late last year.
That's shocking on a car less than 5 years old. I'm assuming it's a diesel. And from this my hunch would be that the car ECU thinks the cars doing a regen of the dpf. If you turn a car off during a regen the fans can stay on a little while after.
Has your mechanic done a diagnostic check to see if any fault codes flag up at all?
I believe you'll need the front end. If you end up with the upgraded xenon lights these will need to be coded to your car and you'll need the bumper with headlamp washers.
You might find more luck for the linkage via VW golf maybe?
For example apparently the current polo wiper motor is the same as my old A6 one according to a good friend of mine.
Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 the new forest is lovely, you should look at coming along to Simply Audi at beaulieu in April. You could be on the club display 👍
Can't say I've heard of this. Usually the beeping is joined with an image in the LCD display. Is the LCD display working?
On my A6 the only time I've had a similar issue is when the engine was off but I was sat with the radio on. I wondered if it was warning me of low battery?
