My mother owns a 2005 B7 2.0 TDi with the 6 speed manual gearbox. For the past few months the car has had an intermittent shudder on hard acceleration. It comes and goes at random and occurs only during hard acceleration (eg: when the turbo is boosting) We have had it at the agent...who say that there is nothing wrong!! What could possibly be wrong??? I suspected a tired engine or gearbox mounting, but I have read some horror stories about failed dual mass flywheels etc! Has anyone experienced similar problems and if so how was it solved??? I am worried that ignoring this problem could cause serious damage to the car. Here in South Africa there have been numerous reports of A3's and A4's with failed gearboxes at fairly low mileages.
