Någon som vet vad vad som är trasigt om denna felkod uppkommer samt att motorlampan tänds:18528 Lambdakorrektion efter katalysator P2096 - 002 - Reglergränsen mager överskriden
Har det med den berycktade Noxgivaren att göra eller kan de vara något annat ?:)
Tacksam för svar:)
Här är ett svar jag hittade på ett forum:
I'd look for an air leak. also check power supply & gnd to sensor. Fsi run low manifold vac in stratified mode which
is why they need a sensor in the vac line. this could also tie in with your nox sensor fault.
Men det slutade med att han fick byta NOX-givaren.

... och från ett annat ställe:
VAG Error Code: 18528
EOBD II Error Code: P2096
Fault Location:
Post Catalytic Converter Fuel Trim, Bank 1 - too Lean
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Low fuel pressure.
Misfire condition.
Large vacuum leak.
Air leak near sensor.
Lean air/fuel ratio.
Faulty Front Oxygen (Lambda) Sensor.
Catalytic converter exhaust leak.
Description:
The catalyst's efficiency is demonstrated by its ability to oxidize CO and hydrocarbon emissions. The Powertrain Control Module (PCM) compares the output signals of the front and rear oxygen sensors to determine whether the output of the rear sensor is beginning to match the output of the front oxygen sensor. Air/fuel mixture compensation keeps the frequency of the front oxygen sensor high due to the changes from rich-to-lean combustion. The catalyst causes the rear oxygen sensor to have a lower frequency. As the catalyst wears, the rear oxygen sensor’s signal trace begins to match the front oxygen sensor’s signal trace. That is because the catalyst becomes saturated with oxygen and cannot use the oxygen to convert hydrocarbon and CO into H2O and CO2 with the same efficiency as when it was new. A completely worn catalyst shows a 100% match between the frequency of the front and rear sensors.
