Hi

I have a 2002 A4 TDi SE. After a few miles the engine feels as if it is running very unevenly (lumpy) and then the traction control warning light comes on very shortly after and the engine continues to run unevenly. I turn the engine off and repeat this process until it the traction control light stays off and then start the engine again and then after a few miles the whole process starts over. Can anyone help me please?
