The 2.0T FSI Cam Follower

The FSI uses direct injection which requires a mechanical high pressure fuel pump to reach pressures that high (upwards of 1800 PSI).  The Cam follower serves as the barrier between the high pressure fuel pump and the Camshaft lobe that drives that pump.  What happens with this is the Cam Follower will periodically wear.  There is a wide debate as to why, which ranges from fuel pump modifications to oil change intervals to quality of the oil used (make sure the oil you use meets VW 502 00 spec).  What many VW or Audi enthusiasts have done is decided to check this as a part of regular maintenance on the vehicle, and replace the cam follower if it shows signs of wear.

If your cam follower does wear all the way through you can expect damage to the FSI Intake Cam Shaft, the FSI High Pressure Fuel Pump, and the FSI Cam Follower.  This can be a very costly bill and should be avoided at all cost. From what we know most vigilant FSI owners check their cam follower every 10-20k miles, depending on the owner.

Cam Shaft Failure or Wear on 2.0t FSI engines

The intake camshaft on the VW and Audi FSI engine drives the high pressure fuel pump.  There was an issue with the earlier revisions of this camshaft where the lobe that drives the fuel pump would wear prematurely.  There is speculation that the metal on the cam was too soft, but we don't have any further facts on that.  What we can tell you is there have been multiple revisions to that part.  The original version of that intake cam was part number 06F-109-101-A or 06F109101A.  After sometime when it was clear there was an issue with this part they came out with a revision part number 06F-109-101-B or 06F109101B.  A short time ago the revision B was replaced by 06F-109-101-J.  Most times when people find this info out they want to know what is different about the “J” vs the “B”.  Unfortunately no one can answer that question, as VW and Audi doesn’t disclose what is changed on any part number revision.

The important part to know is that if you are replacing your camshaft you are getting the most current version available.  Found Here 2.0T FSI Intake Camshaft Rev J 06F109101J
