Hi WOYO, did this conversion to Cayenne 2021, and tested it for 2 weeks. Swapped to battery H8 AGM 92A, start stop works - but not as efficiently as on lith battery ( not a problem for me - I always turn off start-stop), no errors etc. But have one question (I took other nagative cable that you shipped to me (have yours too - but it has the same VAG code )) and when I start a car for the first time (when is cold) it shows on instrument cluster 14.5V which means battery is charged, but when I stop car and start again cluster shows 12.5-12.6V and only 14.5V when I use brake and again drops to 12.5V while driving. Is it normal ?
@@woyosmart52 I thought maybe I hadn’t connected something correctly, because in another Porsche I’ve driven, it always shows 14.5-14.6V right after starting the engine. But here, sometimes after a short stop and then starting it again, it only shows 12.5-12.6V - during braking, it jumps to 14.5V and then drops back to 12.5V.

Yes, it is normal. This is because when you charge your car, the voltage will be higher than what you use on a daily basis.
