My timing chain jumped a tooth, and I think my mechanic and dealership are partly to blame. What to do next?

You cant expect every mechanic you encounter to know every nuance of every model year vehicle they see. Ive driven this platform for 7 years and probably have thousands of posts here and I still learn new things all the time. You cant be mad because the mechanic didn't tear out the engine and inspect every single part. You are being unrealistic and I will also add, the longer you go down the- "woe is me, this is someone else's fault!" road, the longer it is going to take for you to fix your car. Move on to the acceptance stage already and get to work, you are wasting energy.

Looking at your past post here you were complaining about some random misfires at idle. Several posters, including me, told you that it is normal for these cars to misfire at idle and as long as it isn't causing a CEL, to not worry about it. So you cant be mad at the mechanic for telling you the same thing when you initially complained about the misfires.

Now my question is, when you bought the car and test drove it, did everything feel fine? Or was it misfiring then too? When did the misfiring begin exactly?

Next thing, you have VCDS so you should use it. If you go to the engine control module and go to block '93' while the car is warmed up and idling, you can read a value for 'cam position angle' or something like that. it should be a negative number followed by degrees. for example -2.4°

report back

For a lot of cars its not really a common thing to check timing chains during routine inspections unless the car was having issues already or has very high mileage. The cam phase adjustment angle in VCDS can be used in diagnosis but to physically check the timing chain spec its several hours of labor. Also 2014s have the updated tensioner and probably a revised timing chain already. Now that you're throwing codes though I'd take it back so they can do a proper diagnosis now.

As a Audi technician myself. Regardless if it jump timing it’s not technician or dealership service department fault. Used car inspection only consist of a scan for faults and safety things likely tires and brakes. If there was misfires and check for timing chain stretch or measuring through scan tool you would be responsible for additional diagnosis time as well as tear down to physical check. FYI depending what state

example
Diagnose misfires 1.0. Hours (scan tool mostly checking and no tear down testing.
Diagnose physically 1.0 Hours.

if you end up getting it repaired. Keep up with your oil change most car I see at least for Audi is customer who neglect simple oil changes. Good luck
