Audi A3 - Shudder on idle

So my car is shuddering on idle. This only happens when the car has warmed up to operating temperature and worse when the outside temperature is warmer. It runs fine until i stop at a robot for example where it then starts to jerk getting progressivly worse until its rhythmically shaking. If i rev it to 1000rpm the shake goes away. The car idles at 850rpm and doesnt vary at all. Any assistance please.

  • I would check your throttle position sensor (TPS) to make sure the voltage is within factory range. It may need to be adjusted or replaced.
