Hi, similar problem and found a solution.
Ordered a standard edition 1 with metallic paint but otherwise standard in April 22, got the eventually car nov 22. Couldn’t find the options for the ambient lighting on the mmi, puddle light were in the glove box unfitted, no door lights. No footwell lights etc Asked the dealer and they said several new a3’s had come like this and it was just “how it was” due to the semiconductor shortage, theyd try get an answer from Audi. The eventual solution was £150 refund cheque from the local Audi dealer which I didn’t cash. Radio silence from the local dealer, no answer to my emails. Contacted Audi UK, asked to escalate the complaint. Mentioned ombudsman etc. Local dealer called back asked what I wanted and I basically said the missing parts. Told him that I couldn’t get the ambient lights done privately without loosing my warranty. They called me back a week later and offered a new car on the same finance terms for delivery May 23. Keep current car till then. New car 3 year agreement and same monthly fee.
I was never given the option of rejecting the car due to the missing standard features. I didn’t really make a big fuss just explained it’s not what I ordered or expected.
let me know if anyone needs a hand with any wording, I can copy my emails. I was very clear from the start I wanted all correspondence by email for the audit trail.
