thanks guys. next when iam at the car i will disconect the sensor and normally if the problem is the sensor, then the car must run in limp mode but it has to run in emergency.

and then i check the software. i give feedback when i've donw with that

I'm not sure disconnecting will be enough. Car could run with last stored fuel trims (instead of zeros). And those may be seriously bad. IMHO better is to delete adaptations and see if car runs any better. It will not begin adapting until sensors warmed up anyway, so you will have a minute or two before that.

Guys thanks. Now i was at the car, i have screwed up the Catalysator and the car runs Fine. In the cat inside is nothing i think it is anywhere und the exhaust. Now i will check this . I need to install new Katalysator and Update Software because this come from Pop and bang i think .

For the Software Update can i use comfort mode and usw and of the two zb and then Update the dme?

This N53 engine is verry specific. For normal operation needs working NOX system! Lot of diagnostic and theoretical information about this engine You are find here...

Yes, pops&bangs always do pop&bang with your catalyser. It's pretty much mandatory to be removed if you do those...

I do not think this ZB nr came from the factory as it's next to latest. But it is correct for that VIN, so you can use comfort mode. If you have latest SPdaten IMHO it should flash 7635214 instead.

Thanks Next days when im at the car i will try to flash it
