Hello 991uk, first time post here - I'm looking for some diagnostic help...
I have a 2010 997.2 Carerra s - lucky me
Recently the car has been struggling to start. I have owned it 2.5 years and it has always fired within a second of starter motor cranking. Now it seems to be more like 4 or 5 seconds.
Last weekend when starting the car, it struggled (as above) then misfired for a few seconds before stalling. I tried again and with light throttle encouragement, it fired and ran normally. I haven't had misfires since but the slow starting persists. Once the car is warm, I can turn it off and it fires again perfectly without the delay.
My local indy has suggested the High Pressure Fuel Pump and internet research suggests the same for my symptoms. However, most of the stories on the internet relate to a recall in 2011 and I've found very few tales of failure more recently. I called Porsche Reading earlier this week and they confirmed that the recall was completed on my car in July 2011.
So my questions are;
- Does High Pressure Fuel Pump sound likely as the cause? A chap on pistonheads has made me nervous with a story of his OPC chasing a similar fault which turned out to be the ECU and resulted in a few thousand in bills (under warranty thankfully for him!)
- Do HPFPs have a tendency to fail even after recall replacement?
- Would a fault code reader help with diagnostics? I don't currently have one but have been meaning to buy one anyway.
My car is out of OPC warranty and I have used my local indy for everything so I do not have any relationship with an OPC. If I had I might be pushing them for some kind of good will - if it is the HPFP, it will have only lasted about 30K since recall replacement. That's pretty poor.
Grateful for any wisdom 911uk folks can provide to help with diagnostics.
Thanks,
CB-997.2
