The actual value doesn't read 40. It reads 40.0k Again, what happens when you drive it?

When i start the car after a couple of hours standing still i get a very rough idle, like it is misfiring. It also take about 5 to 10 seconds before the car starts. 

The rough idle goes away after +- 30 seconds OR when i revv the car a little bit. Then it goes away and idles 'normal' however even then i don't think it is that smooth as it should be.

I also notice a lack of power when i fully press the acc. pedal. It's just not as smooth or powerfull as it should be even when the rough idle is gone.

Ok i tried with another OBD reader. Seems like you are right. This ones gives me indeed 40 bar actual value at idle. When driving it goes to around 120bar max. But i do notice that my actual value is fluctuating around the setpoint value. not a lot but when it should be 40bar it sometimes goes to 36  bar or 42 bar etc.



But since the biggest problem is at the startup i wonder what the high fuel pressure should be when the car is turned off?

You have all the pieces. Time to solve the puzzle. I'd start with a pressure test and flow rate to make sure your LP pumps are getting enough fuel where it needs to go. If the pumps are original, you'll want to replace both along with fuel pressure regulator and filter regardless as the originals WILL fail, but that's a bit pricey... Could be just a dirty throttle body, a failing FPR, a semi-clogged fuel filter, injectors, coils, plugs, crappy gas, weak battery, wire weirdness...

I will check that tommorow, i am leaving the car 24h without starting to check the high fuel pressure to see how much is gone after 24h.

Do you know what high pressure value it should have with the engine off? I believe it should be at least 40 bar so it can start easily because the idle requires 40 bar too.

I am just trying to eliminate possible failures.

      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?
      Durametric codes:
      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?
