Well I might be having some problems in my '09 now.
I have already had the HPFP replaced twice. The last time was over the winter and I have to check the paperwork, but I believe the HPFP was a 933.
This morning driving to work I got the half engine light, reduced power warning. I thought I have had some longer than normal cranks lately but they seem intermittent.
I shut the car off and turned it back on and the light was gone. I just hope I make it home okay.
I am out of warranty except for the extended warranty of the pump so I hope it is either nothing or the pump. I will bring it to the dealer tomorrow.
