07L109311 – HPFP Fuel Pump Cam Follower

Genuine Audi Part

The 07L109311 High-Pressure Fuel Pump (HPFP) Cam Follower is a critical wear component used in Audi petrol engines equipped with mechanical high-pressure fuel pumps.

Over time, the cam follower is subject to constant friction and can wear down significantly. If left unchecked, it is common for severely worn followers to develop holes worn completely through the surface, leading to direct metal-to-metal contact between the fuel pump and camshaft.

Once this occurs, permanent damage to the high-pressure fuel pump—and in severe cases, the camshaft—can result. This cam follower is a well-known failure point in these engines when not replaced at appropriate intervals.

Replacing the cam follower as preventative maintenance is a low-cost solution that can help avoid costly repairs and extended downtime.
