POPs can you please give more details, about the HPFP. I have the same issue.Turns out a new hpfp fixed the problem. Thanks for everyone's help.
Yes, I've decide to do so. Tomorrow I'll order both HPFP.Replace HPFP then go after no.26, I have not seen people replace safety valve, or fuel pressure sensor #20.
check link below for part number choose your country and engine, those sensors not expensive just labour to get to them.

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!
