Hey you freaks… The knock sensor of my Omi is still killing me! didn’t come through the tuv because of brilliant engine diagnosis!The examiner wrote something about environmental pollution, which I absolutely don’t understand, AU got my Omi without the smallest problem! Engine diagnosis returned;Knock sensor bank 1! So he was changed and the error deleted! After 100 meters of driving the control lamp again lit up again test returned:Knock sensor bank 1…! everything was measured cable-wise and k Ontrolliert, what went to control…everything Ok In the meantime the error has been deleted 5 times but the control lamp still lights up and so I don’t get my badge! Maybe someone has a clue what my omi suffers from? I am grateful for every tip!!!!
