Service
1. Using the hand vacuum pump VAS 6213 check the membrane of the crankcase breather for leaks; a leak
can mean a faulty membrane or elbow piece.
2. Remove the compressor/intake manifold and
check the membrane for leaks directly on the
crankcase breather. Remove the crankcase
breather and check the two metal plates for
damage (Figure 1).
If one plate is defective then always replace
both (included in the pressure regulating valve
repair kit).
