so i finally got my car back from the body shop. i was really excited but now the car has to go back tomorrow. I took it out for a good 50 mile drive and i noticed a few things wrong. First the car would stall while im sitting at some intersections and my foot is all the way down on the clutch. Then the CEL came on. The A/C would cut out and back on randomly, seemed like there wan't as much power as before, and the car ran pretty hot(between the H and the middle). They had to replace the radiator and the pulleys and stuff so im guessing they messed up somewhere. Their parts have a 3 year warranty, and if i need it fixed because of something they did i get it done free, so im taking it back tomorrow. Does anyone know what might have caused the problems? If it helps here's the receipt for what they did to the car.

EDIT: 1.8T by the way

 

I hope they used G-12 antifreeze or universal yellow antifreeze.

 

they're licensed and certified to work on audi's, and the guy who was personally working on my car has been working on audi's for the past 15 years so im pretty sure he did.

 

did they change the thermostat?? is the coolant temp sensor damaged?? it was front end damage so all must be looked at, are the cooling fans sticking?? don't go by its an Audi dealer there are many cheats + bad mechanics in all garages so beware of your confidence

 

it not an audi dealer. the shop came highly recommended from 3 different people and they do all the work for Capital Eurocars(like the only Euro dealership in town) and they have a 3 year warranty on all their work, so i trust them.
