Hi, I have a 850S/NA-94 with 215 kkm.
In the past few years got few times at A1 313=incorrect signal from the gear position sensor (PNP), causing limb-home-mode making the car unusable for my wife.
Thus I now removed the PNP switch, opened it and cleared the contacts with PRF6-68, electronics contact dry cleaner spray, cleaned and lubricated the mechanics with servisol silicone crease there after.
Then I put everything together again without any adjusting problems at all and it seems to work.
It took me 2 hours to take PNP off and again 2 hours to put it back, the cleaner and crease cost practically nothing.
Now I’m exited to see if the 313 pops up again this autumn or do I have few non-problem years ahead, if so then I will repeat this for my 850SW-94 with 267 kkm, which has so far had only once the 313 last autumn.
