Code 012555 low pressure fuel regulation
is coming back.

Is that indicative of the common fuel pump cam follower wear/failure?

yes it is and fix it as soon as possible...

Only changed the cam follower.
Code comes back once in a while.
Hope it holds up until car can be shoved into an Audi dealers rear end as trade in (erase code when pulling into the lot, naturally).
Audi declined any support due to 150k miles.
Note: car has been at Audi dealer several times (among other things: installed new fuel pump, installed new thermostat, etc) while under warranty, but they did not mention or check or follow the TSB that Audi issued for the car.

There is also a fuel pressure sensor that may also be faulty. It sits right near the fuel pump, and I believe it is green in color if I remember correctly.

vtraudt

I changed that one first.

It was the cam follower:

Junius

Wow!!! Since you changed it, how has the car been running?

vtraudt

This is VERY tyipcal. Photos in Audi TSB look the same.
Car runs fine, but code comes back once in a while. Pretty sure the cam and the HPFP have worn.

Audi TSB here fyi:

Didn't Audi warranty this for you?
