Question about Audi A4
Try unplugging the Mass Airflow sensor and see if the car runs better, if it does replace the MAF sensor. It is located in the air intake hose to the engine.

I had the exact problem with my A4 2001 1,9 TDI but i just turned the car on, then first turned the steering wheel to the left as far as it goes, then to the right (i dont know if this is necessary but this is what i did). After i drove for few meters,the light went off and it worked normally.

Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..
