AUDI A4 2007 2.0L Turbo Check engine light on

[TSi]

Hi

I have engine light on..I took few readings but they seem ok including rail pressure in MVB106. Fuel filter replaced.I am not sure what next to do.Has this car got the fuel pump control module under the seat on top of tank? I know we used to have problems with the high pressure pump cam wearing out which affects the high pressure fuel. But i am not sure as reading on 106 seem good at idling. Any hints on this would be appreciated! See diagnosis log:

Check the in tank lpfp controller with measuring blocks and see if it checks out. Clear the codes and if it comes back on that would be what needs to be replaced (either lpfp or controller or both).

I was having low pressure from my lpfp and getting a couple of the same codes as you. Pump was pushing <5 bar (throwing codes). What ended up fixing it was replacing my fuel filter. When was the last time yours was changed? Much easier to do that than replacing the controller or pump...

Btw, where in Laurel are you? I live off 197 between Contee and Cherry Lane.

[TSi]

I am off cherry lane/vandusen near Laurel high school

Gotcha. Nice. Let us know what you end up logging/doing.

I might be able to help out, depending on what it winds up being.
