APR 09-15 Audi TTS Quattro High Pressure Fuel Pump - Rebuild

The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004" and geometric tolerances are as tight as .00005". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and the plunger undergoes a special diamond like coating process for exceptional surfaces hardness and ultra-reliable operation. To prevent float associated with altering the plunger's mass, APR supplies each unit with a properly specified spring. All internal seals are replaced, including the spring seal, and the tip of the pump retains the factory pivoting head to reduce cam follower wear and piston side loading. Fits Audi A3 06-13, A3 Quattro 09-13, A4 05-08, A4 Quattro 05-08, TT 08-09, TT Quattro 09-15, TTS Quattro 09-15; VW Eos 07-16, Golf R 12-13, GTI 06-09, Jetta 06-10, Passat 06-10 Please note, this is an upgrade of your existing pump and requires sending a pump to APR to be rebuilt. The pump and solenoids must be in working order. We will test the solenoids and visually inspect the pump. Failure to package the pump properly can easily result in damage to the pump's solenoid connectors. Also, this engine suffers from cam follower wear from the factory. Replace the cam follower when upgrading the pump. If the follower is destroyed and the cam is worn, this pump may not operate to its full capacity. If the cam follower wears through while using this pump, it can easily damage and destroy the pump. Specific software is necessary to maximize performance from this pump, and is available from APR on most vehicles.
