I have just put my car into an Audi garage as the gear stick is popping out at 3rd or 4th gear when accelerating, Audi are advising that it could be fly wheel or the clutch causing the problem, they have quoted £414 to investigate and recommend that I should replace both the clutch and fly wheel if this is found to be the fault at a cost of £1600, I just about fell off my seat at this cost as the clutch is not slipping and no effect other than the gear stick popping out, i am looking to seek some advise on the best way forward as this seems extreme the car has been in for 2 days and I really don’t think they have done anything, other than carrying out an inspection on the car and telling me that the were issues with tyres, window wiper and an out of date tyre repair bottle they have done nothing over the last 2 days and then tell me it’s £414 to investigate to see if this is the actual problem the car is Audi A1 2014 44000 on the clock
