POPs can you please give more details, about the HPFP. I have the same issue.

I do own a '08 T2 V8
I ran VCDS and got codes, P2294(fuel Pressure Regulator Valve (N276) and P129B
(fuel Pressure Regulator Valve; Bank 2 (N276) with EPC light.

after a few months of doing research reading all of your great input it seems like the (N276) sits inside the HPFP. I Believe there is 2 one on each bank ?

Pops give more info please.

All other mechanics please chip in or guys that have dealt with this issue I really appreciate it, I promise to give back feed back, Club Touareg really saved me a few thousands on this car from dealers!
thanks again.

Replace BOTH HPFP….. Thats all i had to do.

There is a good deal for less then $550 for both HPFP.

That valve on 26 wont give in that easy., HPFP

Dont be cheap like me replacing the sensor on old HPFP they will break when u screw them back in.

Dont stress about the sensor on fuel rail.

I wish someone gave me this advice, lol i did the flanges and everything else in tank and was not needed.

But now i have everything replaced new in gas tank.

Check PCF Euro they had the HPFP dual get the Hitachi OEM, I have 20k miles on mine and no problem so far.

If the spring that pushes on the cam follower is worked out or sensor on the HPFP is faulty it will give you “low fuel pressure “

Good Luck,
