I have an a6 c6 avant 2008.

Currently it will start up for 1 maybe 2 seconds then cut out.
Leading up to this it went into limp mode a few times.
Then on the way home one night the dpf light came on and into limp mode it went. Pulled over, turned it on and off in hopes to clear the limp mode and try to regen the dpf but it was still in limp mode all the way home.
It sat for a few days due to being busy, started it up and took it for a spin in hopes to unblock the dpf but as i reached the end of the road the revs were dying off with no response to the accelerator. it then stalled for the first time on the side of the road.
its been towed the short distance home and has sat since.

it is due a gearbox service as it was starting to get clunky at low speeds.

here are the scan results

I would start by looking at the Intake Manifold Flap motor V157.

I don't know which engine you have but it will be mounted below the inlet manifold.

It gets blocked up with EGR crud that stops it moving throughout its full range.

Give it a good clean & check inside the plastic side cover for any oil & damaged plastic gears.

the engine code is BRE.
i have just removed it and given it a clean but still the same result. ive been told it was replaced about a year and a half ago.

any other ideas?

The only code in your scan that could cause the engine to die was the flap motor.

Your scan also shows that the battery isn't too happy & intermittently has a low charge, so possibly a problem there.

The voltage on the flap motor in the scan is only 9.42v which is obviously a problem although shows as intermittent.

Voltages on other modules shows the battery charging ok.

There is virtually no monitoring of the fuel system on the PD engine, so I would check your in-tank fuel pump is running ok when the engine stops.
