I've read above but my problem is the stop start works when I remove the plug from bms then plug back in ..the start stop works until I switch of ignition again, then it no work , If i remove plug again for 10 seconds and plug back in it works again, I have new batteries, I'm at a loss.

Hi Naks
Think it should do, I have similar setup Optimate charger not Ctek but same connector, goes into a twin 7 pin convert to the 13 pin on the car and has worked fine

Have only used it once just to make sure it did work

 Porsche Cayenne 2022
gone Porsche Cayenne 2020
gone Corris Grey HSE Dynamic 2016
gone Ipanema HSE lux 2010
gone Rimini HSE 2005
!!

Thanks for the info!

I checked my car and it also has the 13-pin socket.

Just ordered one from the forum shop  --
