Genuine VAG 2.0TFSi Fuel Pump Cam Follower - 06D109309J

Genuine VAG 2.0TFSi Fuel Pump Cam Follower - 06D109309J

The high pressure fuel pump in the 2.0TFSi engine can be affected by excessive wear of the cam lobe and the follower that drive the pump. The factory solution was to increase the hardening of the cam lobe and as of 2006 all 2.0TFSI's have harder cam lobes.

This issue is not limited to remapped/modified engines and can also be found on completely standard set ups. This affects the OE fuel pump and all versions of aftermarket up-rated fuel pumps. This issue is not a direct result of remapping. However, extended periods at very high RPM €“ such as aggressive track day driving €“ can cause rapid deterioration.

The recommendation is that an inspection of the cam follower is done at each service interval/10,000 miles (on a standard engine).  For vehicles that have been re-mapped and/or have an uprated fuel pump then an inspection every 5,000 miles is suggested whilst cars that are used for track days should be inspected after each event.

This issue is more prevalent on some aftermarket high pressure fuel pump kits than others, however all OE and aftermarket TFSi fuel pumps are affected by this issue.

This item is a genuine OE replacement part direct from the VAG group and is always held in stock here at AKS Tuning.

The cam follower is item number 6 in the diagram above

We also sell the cam follower as a kit which includes a replacement seal, and x3 new bolts for the high pressure fuel pump.

At AKS we do also produce a kit which utilises the cam roller design from later TSI engined vehicles, which is an immense upgrade over the standard cam follower and is designed to be fitted, and then not require replacement. Please see the link below for this.
