I'd check them if you had a leak. Better to be safe than sorryThanks Minim, saw a YT video from a Porsche mechanic doing something similar to a mk1 Cayenne and wondered if my wires are frazzled too.
Haven't been brave enough to remove the sezts for a look. Plus I don't have a heat gun. But it sounds straightforward once you get down to the wires?
If I did it myself how would I know what gauge wire to get?
You need a soldering iron to cut away the bad wire and resolder. For heat shrink tubing with glue I've used a lighter or a hairdryer. It doesn't take much to heat it.
regarding gauge I don't recall but If I where to guess there was some 0.75mm2, one 1mm2 and a 6mm2. All my wires were long enough to be cut and spliced so I didn't have to buy more wire.
