Initial publication
Customer states:
 Oil loss in the engine compartment, front end, and the filler cap.
 There is a smell coming from the engine compartment.
Workshop findings:
 There are traces of oil around the filler cap.
Technical Background
A faulty membrane in the breather line can result in excess pressure in the crankcase and therefore some oil loss
through the filler cap.
Production Solution
A breather line with an improved membrane has been implemented in production.
Service
Replace the breather line
(different variants available,
only order by VIN) (Figures 1
and 2).
