sitting in traffic this evening, the battery died rather quickly.

its been fine of recent times, starting on the button despite the cold and frosty mornings. after a long run, sitting in the traffic, messages started popping up on the dash, suspension fault, traction control, HDC, airbag, adaptive lights CEL. plugged in the GAP IID tool,, looked at live values, battery reading 7v. limped it to the nearest Halfrauds.. no correct battery (YUASA YSB019) in stock. not enough juice to turn it over, borrowed a jump pack off the Halfrauds guys.. not juicy enough to kick it over, get the jump leads out the boot and politely ask a couple of blokes for jump who happily obliged. tear round to the Halfruds that have 8 in stock, 10 miles away, purchase it, with fitting, turns out the fitter is too short to reach and lift the battery, so I do it for him.

start it up, all good with the world, plug in the IID tool, clear all faults and all is even better with the world.

kind of interesting how it died and its true the L322 flashes like a Christmas tree when the battery is on the fritz and its good to have a GAP IID tool in the glovebox
 
14.0 to 14.2 on the voltage with the new battery. With a high electrical load on
That is low, should be at least 14.7 volts. Might be worth checking the earth from engine to chassis. Also, if you can get at it, put you meter across the output of the alternator at the alternator. It's not unknown for the positive cable to corrode away inside the sleeve causing excessive volt drop.
