Jerking at idle / no load (TDI)
My engine (TDI) shakes at idle, usually when it is warm as the air conditioning running. Where is the problem?
The modern TDI engines have been developed under the focus of a particularly low fuel consumption and low pollutant emissions. Therefore, these engines run at idle very "lean", which can be felt by a "non-round" or "jerky" idle. A slight jerk in the state is therefore almost inevitable. In some engines, the stuttering occurs, however, very much in evidence, can be tackled may remedy:
1.9 TDI (74 kW/100 hp, engine code: AVQ)
In this motor, the bucking can sometimes be reduced by the adjustment of the camshaft synchronization angle and AND LOWERING OF IDLE SPEED. Since the timing of the camshaft is not trivial, one should take this action only if the stuttering is extremely disturbing. A modified software is not available for this engine.
2.0 TDI (100 kW/136 hp, engine code: RWH)
If this engine creates a software update of the engine control unit remedy against the rough idling. The software has the number 906 016 03G EH 5687 and can be played by an authorized Volkswagen dealer.
