Car back, all scanned and no fault codes present. They changed A NOx sensor but the lady on reception couldnt tell me which one other than 'Bank 1'...which i am not sure means much as i dont know if it was pre or post cat.

Either way....all OK for now....will come back if the fault ever comes back.

Thanks everyone
