The seal replaces the o-ring found on the Constant Pressure Valve (11 11 1 318 185). It is very rare for the CPV to fail, it is usually the o-ring that fails, and it is not available separately.

The CPV is found on the S50B32 and the S54 engines. Click here to see the part illustrated on RealOEM.

The seal that I supply is VITON. VITON is superior to NITRILE as its temperature range is higher, as is its chemical and oil resistance.

The price for the CPV from BMW (as at Sep 2016) was £33.31, so £10 represents a massive saving for you!!

Below is a video that I made showing the problem.
