Hi I have an ongoing problem with an Audi Q7.

For a while it gave an intermittent problem with limp mode when the car was pushed hard.

Gave it a scan & it showed 13128 & 04195

Turbo accuator & fuel pressure

So cleared the codes & drive it hard again limp mode comes back with only fuel pressure code on vcds 004195 & no turbo code.

Changed the fuel filter, still the same, changed the fuel rail pressure regulator on the back of the rail & the problem has gotten 10 times worse.

Has anyone had this problem with the Q7 could tell me a good place to start
