I have had this code in my 2008 Audi Q7 3.6L for a while and after some research in the past, this is a tough one to fix on Audi vehicles.. This code can be triggered by malfunction of many components like the fuel pump, High pressure fuel sensor, low pressure fuel sensor, dirty fuel filter or even the cam sensor.

I have yet found out an incident specific to the Q7 so I am asking here if any of you have experience this code and what did you replace to fix it?

thanks!

replace fuel filter in your fuel tank
i think you have two of them one on each side.

lmao.. just had the same problem on my 07' 3.6L.. replaced the fuel filter in the tank and that should fix it. you might want to replace the fuel pump while you're at it too if you can spend a little extra. it will probably save you in the long run.

don't spend money on the sensors and crap under the hood.. doesn't do anything.

I did replace one fuel filter around two weeks ago. I replaced the one under the back seats driver side. Is there another filter on the back seats passenger side?

I bought the whole filter housing that included the filter in it, do you know if we can get the filter itself?

Thanks

My bad look it up inside the manual. One side is the filter and the other side is the pump.

you can do both with a filter (it self) or (filter and housing).
My opinion since your have a 08 and this might be the 1st time i recommend for the whole unit, cause plastic case can be crack or will in the future cause of it been to old.
