Good evening people, have recently a following engine wobbles in front of the engine compartment and also in the interior the seats vibrate. it is not always there fall but sporadically! according to diagnosis ÖAMTC P2196 Lambdasonde (bank 1, Sensor 1) system too fat. I recently changed the throttle flap! But after the throttle exchange did not make a problem. Would be very grateful for the possible help! Have still error messages in the display when I turn on the ignition but then they go away when driving: F ochler Werkstatt Fahrwerk die Audi Werkstätte has said it can only be a dealer from the chassis broken, how can you go ahead? Air suspension obviously does not lose air! Errors stop braking. Brake pads are fine. However, it is sometimes difficult to get the automatic lever out of this connection with the electric hand brake. THANK MFG
