I have a 2009 997.2 PDK Carrera 2 and am getting a loss of power and this error code:
2510: Fuel high-pressure control - adaptation. Value below lower limit value
I believe this means my HPFP is dead and am looking for the workshop procedure for replacing the high pressure fuel pump HPFP. I have looked far and wide for a DIY tutorial on this, but found nothing. My local stealership will do the work for $900 labor plus parts. I have sourced the pump for $850 and want to do the work myself. The pump looks readily accessible at the back right end of the engine, facing the rear bumper.
I am happy to write this up as a DIY with pics if someone can forward me the workshop manual pages or procedure?
First time post... hope to start contributing to the forum now!
09 GTS with 93k and excellent maintenance history, recently getting long cranking times and sometimes rough idle at startup. Starter is working properly so we can rule that out - not sure what to tackle first, coils? fuel pumps? HPFP?
1023 Ignition Coil D Primary/Secondary circuit - upper limit value exceeded
1026 Fuel high pressure implausible - value below lower limit value
The 1023 keeps coming back when cleared but never throws a CEL, the 1026 has been very intermittent but will throw a CEL.
I swapped coils 3 and 4 (assuming D is coil 4 and coil 4 is rear-passenger side of engine?) and still get the 1023 code for "D" but no misfire codes.
I tried pulling fuses 13 and 14, independently, and truck starts on both fuel pumps (with long crank).
Logged with Durametric the fuel setpoint vs. actual pressure and I get 40bar at idle and it seems to keep up OK while driving up to 120bar at WOT.
Plugs were changed at 80k but I believe to be on original coils and fuel pumps.
So before I start throwing parts at this, any advice on what to troubleshoot next? Still fairly new to the Durametric so anythink I'm missing there with respect to data logging?
