shaking passat

Chances are that some valves were bent and not seating properly. At tickover, the ECU is controlling the smooth running by constantly monitoring the engine rpm. If the engine speeds up, then he is injecting less diesel to the next injector to slow the rpms. If one of the pistons is loosing conpression, you will have the same issues. Did the garage done a leak-down test ?
