HPFP cam follower replacement

Usually I replace the 2.0 TFSI engine HPFP(High Pressure Fuel Pump) cam follower each 20 thousand kilometers.
It's a small but important part, that needed to be replaced at the time. If it breакs, this will lead to the serious engine damage and expensive repair costs. See this as a warning.

Following photos of the replaced cam follower (original part number 06D109309C).

Camshaft is OK

This work should be performed by a qualified mechanic using an appropriate tools

Odometer: 59,500 km.

40K service

We're passed 40K km.
This is the regular oil change service, but it was done with some little additions.

Oil: Engine oil (Valvoline SynPower 5W-40, VW 502 00).
Filter: Mann HU 719/6x.

Also, the cam follower was replaced with the new one.
I'll show you comparison, that may be interesting for the 2.0 TFSI car owners. Two cam followers, that you can see in the picture below, passed 20K km.

The left one worked harder, because of HPFP upgrade. In general, the higher fuel pressure leads to the higher wear of the cam follower. The right one was installed prior to this upgrade and worked with the stock fuel pressure.

The brake fluid was changed from standard DOT4 to ATE TYP200 DOT4.

ATE TYP200 brake fluid

 Its advantage is higher boiling point, then stock fluid, that critical in the hard working conditions. Also the suggested change interval for this fluid is 3 years as opposed to only 2 years for the stock DOT4.

The brake lines was changed to stainless steel ones from HEL performance.

This line kit eliminate that 'spongy' feeling often found with rubber hoses under extreme braking condition. 

That's all for now.

HPFP upgrade

High pressure fuel pump (HPFP) is a one of a components in 2.0 TFSI engine, that strongly affects it's performance.

The 2.0 TFSI specific Hitachi fuel pump is driven by the engine camshaft, through the cam follower and produce the pressure, that enough for the stock engine power, but it not able to achieve the pressure level, that needed to bypass the 300 HP mark. Furthermore - it's max fuel pressure in the middle range RPM's is not enough to produce the amount of power and torque, that's supported by the engine in this range.

OK. That's the problem of 2.0 TFSI engine. What's is the solution?
The solution is comes in face of the Autotech HPFP upgrade kit.

The guys from Autotech say's, that: "Our HPFP Kit can achieve flow rates 50% higher than the original pump, essentially removing pump limitations from the equation, even on high-end turbo upgrades."

Also, the cam follower has been expected and found in the good condition.

However, it has been changed to the new one. According to it's wear condition, it may reside without any problems for 30K km.
Cam follower and the camshaft in the 2.0 TFSI engines has at least two revisions. It's strongly recommended to use the latest revision of the cam follower, that made from more hardened material.
Cam follower part#:  06D 109 309 C. The previous revision was: 06D 109 309 B. Don't use it anymore. The malfunction due to wear or break of cam follower will lead to serious engine damage!
Fuel pump O-Ring also was changed to the new one. The ring part#: 06E 127 248.

Autotech provide the detailed DIY instruction about how to upgrade the fuel pump. But my suggestion is to perform installation in the authorized garage, that have the knowledge and the tools to deal with the engine components.

OK. That's it!
The HPFP fuel pressure limitation has been removed. Now, the engine ECU is ready to be upgraded with the new program, that will take this fact into account.
The result? There will be more power! Very soon.
