The High Pressure Fuel Pump (HPFP) has had some issues on the FSI (Pictured below). This is most often related to damage done to the HPFP after the cam follower wears through. When the follower wears through the tip of the high pressure fuel pump will ride directly on the lobe of the intake camshaft damaging both the high pressure fuel pump and the cam shaft. As the FSI are now getting a little higher mileage on them we have seen failure of the N276 which is an electronically controlled regulating valve in the fuel pump. The N276 is not a serviceable part and can only be replaced by purchasing the entire high pressure pump.
If you have faults relating to the N276 or other high pressure fuel pump faults, you should always inspect your FSI High pressure fuel pump, cam follower and camshaft lobe to ensure no further damage exists. This is always the easiest way to verify you do, or do not have an issues mechanically with this pump. Please note that if your high pressure pump has become damaged you should not attempt to re-install it to try and see if you can get away with not replacing it. Failing to do this could potentially mean damaging any new parts in the system, or even major engine failure if the pump breaks apart sending metal shards through the engine.
Please note there have been multiple revision of this VW and Audi High Pressure Fuel Pump. You should make sure when purchasing a HPFP you get the most current version.
