Dave997S Posted 29December, 2019 Report Share Posted 29December, 2019 We’ve been away for a bit and the 997 has been tucked away in the garage. I thought it’d be best to take it for a run and the ABS light came on. Rather than going straight home I pulled over and switched it off (in same vain attempt to maybe reboot it like a PC). It wouldn’t restart, so we sat and waited for  a tow. Instead of a nice meal at a local winery, we ended up having ham and cheese toastie for lunch. All in all a grand day out. Put it on the trickle charger and 2hrs later it fires straight back up. Next I need to suss out if it’s just battery or starter or starter / alternator cable. In the mean time it’ll go on the trickle each night.   Troubleshooter 1 Quote Link to comment Share on other sites More sharing options...
PIC Posted 29December, 2019 Report Share Posted 29December, 2019 Sorry to hear Dave, Battery voltage can reek all sorts of havoc on modern cars, have your battery checked first. Dave997S 1 Quote Link to comment Share on other sites More sharing options...

dan_189 Posted 30December, 2019 Report Share Posted 30December, 2019 As Mike mentioned I'd vote alternator to starter cable - also prevents the car from charging the battery properly. Quote Link to comment Share on other sites More sharing options...
Skidmarks Posted 30December, 2019 Report Share Posted 30December, 2019 I’ve found even slight loss of voltage will prevent starting.  These newer cars are very sensitive in that regard.  Dave997S 1 Quote Link to comment Share on other sites More sharing options...

dan_189 Posted 31December, 2019 Report Share Posted 31December, 2019 @Francois on here tackled it himself on his 997 - new starter and cable. Think there is a thread about it floating around here somewhere. Dave997S 1 Quote Link to comment Share on other sites More sharing options...

911 Snake Posted 9January, 2020 Report Share Posted 9January, 2020 Agree with when the battery is low all kinds of electronic issues can pop up! (sunroof operating on its own, airbag light, seat bolster pressure automatically increasing!) Similar thing happened to me a while back which turned out to be the phone/factory Motorola module under the drivers seat that was still pulling currant when the car was off. This all started when I had a Mobridge Bluetooth phone kit installed and the installer only disconnected the phone functionality from the PCM unit and not the module under the seat as well. I was getting a flat battery every 3- 4 days without driving! Drove me mad. Initially to troubleshoot had the the entire starter loom and everything replaced (15yrs old so I can smile now and just call that preventative maintenance) but, all it turned out to be was one plug that needed to be disconnected under my seat!  My guess is a good recondition cycle of your battery with the trickle charger overnight before you take her out, especially if you're not driving it for more than a week or two at a time. Good luck Dave997S 1 Quote Link to comment Share on other sites More sharing options...
dan_189 Posted 9January, 2020 Report Share Posted 9January, 2020 Here is the thread on the replacement cable - the procedure to the 996 is similar but not exactly the same for the 997 Â Dave997S 1 Quote Link to comment Share on other sites More sharing options...
The Caretaker Posted 14January, 2020 Report Share Posted 14January, 2020 Hi Dave, I have a 997 CS2 same vintage, artic grey would be the only difference and no red seat belts if you remeber. Seems to me that if you have been away for an extended period thats to much of a coincedence, particularly if the car wasn't on trickle. I have the C-TEK charger with cigarette lighter adaptor, every time the car goes back into the garage in goes the adaptor to the cigarette lighter, and touch wood I have never had a problem in 5 years of ownership. Quote Link to comment Share on other sites More sharing options...
dan_189 Posted 14January, 2020 Report Share Posted 14January, 2020 I've got the C-tek charger and was able to get by until I figured out the cable was the problem. If the cable is toast the car wont charge the battery properly. Quote Link to comment Share on other sites More sharing options...
