Cayenne LiFePO4 Battery warning light

Post by ROSS79 »

I'm sure there lots of people on here with more tech knowledge than me!
My 2019 3.0l 41k Cayenne is showing 'Battery Low - inspection necessary'. The battery shows 13.4v before starting the engine & has not had any starting issues. OPC Swindon advised a new battery is needed (£1600!) But there are lots of posts on Rennlist.com regarding the same issues & pointing to the electronics in the battery - seems this can be repaired (in the US). OPC will not consider a 'repair' - just replacement. Any thoughts

If you can get the BMS out and find someone in the UK to repair, or update the software.

Because it has PORSCHE written on it................other LiFePO4 batteries from motorsport outlets can be had for around £300
