S3 8p cutting out idle help no EM lights!

A fuel filter being blocked or a failed lift pump will not cause the system pressure at the high pressure fuel pump to be too HIGH and neither will a worn pump cam follower, with those problems the pressure would be too LOW. Firstly the figures displayed in measuring blocks need to be studied and there are known issues with the G410 Low fuel pressure sender 06E 906 051 K

004767 (P129F) - Low-Pressure Fuel Pressure Regulation: Pressure too high
012555 (P310B) - Low Pressure Fuel regulation: Fuel Pressure: outside Specification
018972 (P2540) - Low Pressure fuel sensor - Range/Performance

Thanks so wherre do i go from here?

[magic123]

Its p2540 not 2450?

I have changed that code, as I said the measuring blocks need to be studied by someone with the equipment and the knowledge to understand what is going on, barking at fault codes often leads to wasted money.

I dont know anyone with the equipment and need to use the car but dont want to so im stuck?!

Take it to a VAG specialist or an Audi dealer. You can't expect people to tell you what to replace based on a single code read of codes that SHOULD make the engine management light come on and on a modified car, it could be anything BUT it is likely to be the G410 sensor as it is a known problem with those fault codes.
