Hi guys just picked up a 2017 sdv8 AutoB.
Bought as a non runner but started right up on new battery HOWEVER.. But etc It will start everytime with say a 10 min window but if left longer sometimes it wont crank at all ( all ign lights etc are on )
Disconnect the battery and then reconnect and she'll fire right up.
Have few codes coming up but nothing relating to this.
Anyone gime a steer before I loose my last few hairs?
Thanks in advance

Is it possible that you have a faulty BMS module? Current yokes
