What is the reason for the shaking of Audi A6L 2.0T cold car?

This kind of fault is recommended to go to the repair shop to test the idle motor. If the idle motor has poor working performance or the throttle voltage is not within the standard range, it will bring this kind of fault.

If the vehicle "turns off at idle speed", we can take the following corresponding measures to avoid the danger of turning off:

1. If the engine stops while waiting for parking, just restart the engine. If it is an automatic car, before restarting the engine, you must first put the gear into the parking gear (P gear) or neutral gear (N gear);

2. When the vehicle turns off during taxiing, don't panic, keep the direction stable, and take a little braking as appropriate. If it is an automatic car, first carefully shift the gear to neutral, and be careful not to shift to reverse gear (R gear) by mistake, otherwise the transmission will be damaged, and then restart the engine. Of course, you can also turn on the double jump light to stop the vehicle and restart the engine;

Don't be nervous and keep the direction stable in case of flameout when braking. Measures can be taken to increase the braking force, while paying attention to the surrounding situation. If you have the chance, you can change lanes and bypass the obstacles in front. Pay attention when turning the steering wheel, because without direction assistance, the steering will be heavier.
