Hi, he's probably right, you got no power and the dash looks like a christmas three, so yes, the engine or the auto box or somthing else is wrong ... So far I've guessed you have an A6, and it's an allroad, engine is... 2,5 tdi ?

If an fault accour right after visiting a garage, I always suspect there is no coincidence even if this at first sight looks like a faulty/ loose brake switch.
Scan on tuesday and take it from there
