Porsche Enthusiasts Club Forum

So, my friends 981S had to replace the battery, which just died on him. with the new Bosch AGM battery in place, the car seems to attempt a very brief crank occasionally & then nothing. Charged the battery full & even tried it on my 944 S2, which started immediately.

Car was given 4 year full service at Porsche last December. But, now every time you turn the ignition key on, the car states "Service Now". We have set the date & tried cranking numerous times, but no starter, except as mentioned, very rarely you hear the starter just about to engage & immediately stops.

No warning messages either.

Any help really appreciated.

From my research so far, it is most probably the Vehicle Tracking System (VTS) at fault. This seems to be a Cobra product fitted by Porsche.

No need for it here & apparently, do give problems, leaving car stranded.

My question now; how can I remove it from the car?
