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 is 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.
