Default 2012 A6 3.0T Motor Mounts or Valve Timing Issue

About a month ago, my 2012 A6 with 49K miles started to idle roughly. A local repair shop diagnosed the issue and found bank 2 intake and exhaust cams out of time and showed me with the head covers removed using an Audi gauge that the cams were out of line. they said that a repair would require dropping the engine and would be expensive. I decided to take the car in to the local Audi dealer. The dealer says that motor mounts are bad and need to be replaced for $1700+.

Need advice on what to do. Concern that if I have the dealer fix mounts, would still need the valve train repair.

Advice, please.

sorry - just saw this on -

Dealer did state inspection and said that the motor mounts need to be replaced on my 2012 A6

Still looking on line to see if you can DIY the mounts

I would believe the dealer - wouldnt think the car would run with the cams out .....

Audi engines are interference motors with means if the cams were to be out of time even a little the motor would destroy itself... you would probably have bent valves and possibly valves that have blown holes through the piston heads if the cams were not in time with each other. id go with the dealership on this one but find a cheaper mechanic to do the mounts 1700 is way high for this job. only took me like 2 hours to change mounts out on mine
