2020 Audi q5 -30k miles
I noticed the vehicle making a ‘judder’ when driving in November - no warning lights etc. booked it in with the dealership that I bought it off. They had the vehicle for over a month and said that it was the differential due to excessive wear??? With a car with only now 40k miles and 10 of which I have accumulated (covered under warranty) put in a repair kit and changed the oil within this part. Phoned and said the car is 95% better but not 100% and basically gave the car back to me and want it back now in January (couldn’t do anything more over Xmas and new year) they want it back because they think it could be the prop shaft which they will have to make another claim for.
My question is though the dealership are being accommodating and I have the warranty I have lost confidence in the car, I’m concerned as i assume all these parts are interlinked and causing damage.
Can I approach for my money back or replacement Vehicle?
