Techi-Tom Posted September 26 Share Posted September 26 ok, why do you know there are no O2 Sesor? Without O2 Sensor it is not "legal" to run this Car in EU.. I do not know if there is a "Cheating" device installed because normaly without O2 Sensor the Engine failur light should be on. Final answer to your question: I have no idea. 0 Quote Link to comment Share on other sites More sharing options...

It is for sure illegal to remove them on a car registered in EU. But in case of an imported car, which doesn't have O2 Sensors from factory its maybe possible to get such car legally registered in the EU. 0 Quote Link to comment Share on other sites More sharing options...

Do you see there exhaust manifolds with threaded connections with plugs instead of O2 Sensors? Another question: How do you know the car runs rich? 0 Quote Link to comment Share on other sites More sharing options...
driver1313 Posted October 3 Share Posted October 3 Die LS wurden ab Werk tatsächlich für GCC-Länder ohne Katalysator ausgeliefert, die Fahrzeuge des Feincode UCF20L-AEAGKV haben keinen Katalysator im EPC eingetragen. 0 Quote Link to comment Share on other sites More sharing options...
driver1313 Posted October 3 Share Posted October 3 Außerdem gibt es (auf meinen LS bezogen) für diese beiden Fahrzeuge IMMER einen anderen Kabelbaum, sei es Motorraumkabelbaum, oder Armaturenbrettkabelbaum (ECU <> Lambdasonden geht im Innenraum entlang). Die ECU ist auch eine andere, sogar für Deutschland ist sie von den restlichen Europamodellen zu unterscheiden. Der Wagen ist nicht mit einfachen Verhältnissen nachzurüsten. 0 Quote Link to comment Share on other sites More sharing options...
