About 8 months ago the keyless defective on my MFI came on in my 2012 GTI. After replacing the battery in the fob and troubleshooting different things, I made sure the wire to the antenna located behind the rear seats was properly connected. It was but I suspected that the wire was pinched under the seats so I smoothed it out and jostled the cable a bit and sure enough it worked. Kessy worked fine until a month ago. That’s when the Kessy on the driver door started to intermittently not work and eventually stop working completely. It threw DTC B116B13 (driver exterior door handle touch sensor open circuit) and B116F13 (driver Access/start system antenna - open circuit). All the while, Kessy on the passenger door worked until a few days ago. Up until then the keyless defective message came up sporadically but now it’s all the time.
I did a quick visual inspection of the loom and it looks fine. No visible sign of water damage. I rechecked the wire harness to the antenna behind the seats and found some fraying on the black wire. I was wondering if this could be the reason for my Kessy problems and any suggestions on how to fix it?
Thanks so much!
