Thank you, I’ve got two new ABS sensor harnesses from the dealer in order and am thinking about the ABS control module but agree wiring could be an issue. I saw a bundle under the vehicle that looks like it’s an exposed consider of a connector bundle so I’m heading down the wiring path for sure! Thanks again.

14 Cayenne Turbo S has numerous system failures. PSM codes won’t clear. Right front ABS wheel speed sensor fail message and replaced all four with new sensors still won’t clear. Replaced all plugs, coil packs and the MAP sensor as well as battery (coded battery properly). Thinking it may be wiring harness or ABS control module since PSM failure could be caused by anything within ABS system failure which will fail multiple other systems. any ideas will help as I have very few at this point. Spent $2000 at stealership already abd have determined they are only as good as the technicians they employ as the Porsche training and certification process is pathetic and only teaches how to use PIWIS to interrogate the computers and teaches very little actual critical thinking or troubleshooting skills never mind anything about how the Porsche systems actually function or how the modules work with each other!
