De-cat, P0423 & 33 and Kleemann tune
Hello all.
About year ago I bought installation of Kleemann headers and ECU upgrade at Kleemann hq @ DK. Wondering why I still got P0423 an P0433 codes but no CEL. CEL light does come on at every start up like it should but never got CEL when codes stored. Even while back when I had missfire codes but still no CEL. Makes me think what actually is that tune? I have heard that with original MB Star tool you can activate and de-activate CEL light.
Does anyone have inside information what kind of tune is that Kleemann tune? What does it do? What parameters are modified?
Any one here with Kleemann tune or Rentech or what ever? Do you still got those codes stored if de-catted or with headers?
Too bad that my car came with 280kmh limiter from the factory so even testing that is hard.
