Coils were new around 9 months ago. Starting is very variable. Some days good, some days bad. I'm going to do the for and filter and work from there. Moving coils is the ne t plan but I get a feeling it won't move with it Dealer senior tech thinks hpfp dieing... It's an expensive swap tropics exercise....

Just spent way too much on a new battery from Porsche. The starting is slightly better but still too variable for my liking and getting the 1023 code. Looking at DME set point vs Actual for the HPFP looks OK but I think the regulator might be funky as pressure seems to be a little erratic under load. Tank pumps are giving 5 bar so they look OK

Thanks. the dealer told me that the regulator should be ok and that the filter is a lifetime part! I guess there's no harm in doing these as they are relatively cheap.

Did you find a fix for this? I have the same issues on my 2009 GTS. Dealer changed battery claiming that is the issue but still facing problems
