Nez_Pottage Posted January 3, 2021 Share Posted January 3, 2021 I have a 2015 X-Trail (T32 1.6DCi Auto) which is often, but not always, coming up with a Stop/Start system fault warning on the dashboard when starting up. So far I have changed the battery for a new start/stop compatible one for this model (so the shop says), and bought a charger to make sure it was fully charged. Still getting the same issue though. Sometimes if I go for a motorway run, next start up it will be ok, and may be ok for a few drives, but then comes back again. I did get my local garage to do me a favour and put their computer on it. That showed lost of Voltage errors, and once cleared it was ok for maybe a week or so. When I tested the voltage on the battery with the engine on and off, it does seem like the alternator is working. From memory the battery was 12v off load, and 14v when engine running, so I assume it is being charged ok. Before I take the expensive step of a Nissan dealer for diagnosis, has anyone got any other troubleshooting steps? Link to comment Share on other sites More sharing options...
LeeW77 Posted June 28, 2023 Share Posted June 28, 2023 I have a 2017 X-Trail and I am also getting the Start/Stop system fault. I am guessing by the lack of replies to the earlier thread that this is going to continue to be a headache for me! I have read endless posts about possible causes but none of them have sorted my problem. I have had 2 new batteries fitted, the alternator is fine, the car is used daily. Sometimes the fault will go off on it's own but it comes back. It really is doing my head in that I can't find a fix to this problem. Any help appreciated.

Trevor Posted June 29, 2023 Share Posted June 29, 2023 Maybe a case of switching it off and not using it on every journey Usually does come down to battery voltage so check the Earth leads and connections to the body and battery are in good condition Link to comment Share on other sites More sharing options...
LeeW77 Posted June 29, 2023 Share Posted June 29, 2023 Hi, yeah all battery and connections have been checked and once the fault comes on, you can't then turn the start/stop off. Link to comment Share on other sites More sharing options...
