Long Cold Start with Diff Error
Hey Everyone,
I have an interesting problem the dealership is currently working on. Cold start takes a solid 4+ seconds to fire up and once it’s running I get a diff malfunction warning error for a couple seconds and it self clears.
it had the extended range fuel tank rattle, so the fuel tank was replaced. Additionally the fuel pump and pump controller w as replaced to solve to long cold start issue, but that wasn’t it.
Im wondering if anyone had a similar issue or thoughts on this.
Edit: 2022 GT3…July 2021 build. Stock car

I will double check which one they replaced… I did see a thread for long cold start that had that but apparently it didn’t fix it iirc

I had that too. Long start like battery is dying - after few batteries, turned out to be HPFP

Got the car back after a month, ran great for a day, new high pressure fuel pumps that took 2 weeks fly in from the factory,
now its scheduled to be on its way back to the dealer on flat bed, now in limp mode,
error message: Engine control error, Driving permitted,visit workshop
back firing, no power,
hope it can be fixed, 20k miles

I am having similar issues on a 2020 911 S. I had the low pressure pump replaced, then the 2 high pumps, check engine light is still on, and we are doing a last effort to replace the low pressure pump once more.
