 Battery Replacement | DIY')){kind=link}
Thanks again for taking car of my PIGs power problem! These things are soo dang sensitive to not having the correct battery in them.
Back story for anyone wondering, this Cayenne was having issues with cold starting (super slow to no crank) as well as random suspension faults and other strange gremlins. Battery in it tested as good, but we noticed it was the wrong spec for the build. This Cayenne called for the larger H9 battery with 110 Ah Vs the H8 battery that was in it. Gobs of stupidity was solved just by putting the correct battery in it.
TLDR – Porsche electronics are super picky.
I don't want to think how much of a pain this would be if the battery was dead.
Also, do these cars need battery coding?
Leave it to Porsche! Nice DIY, I don't know I would have believed it otherwise!
I’d like some Mercedes content too 🙂
Love watching Jay….great DIY
