Hi every one. Car is 318D Touring LCI year 2008/09.
A while ago i got an error on dash :
Code 4933
Measured air mass compared to the calculated to low
Anyway, changed Airmass filter still the same problem (amf same part number replaced)
Then changed the air preasure sensor that connects to the intake nanifold, no changes still the same. Replaced a breather hose pipe which was cracked and no changes. Any one plz can help? Thank you
