I was away the last couple of weeks and noticed today that the onboard clock is slow by about 30 mins. I'm assuming the lack of driving is responsible but 30m seems like a lot. Battery issue? I'm pretty certain the battery is factory original. Is it time to get it replaced?
Are you noticing any other issues like intermittant random lights flickering on the speedo display? Maybe check the battery is charging alright, might have a cell on the way out.
Nothing like that. I checked for faults and there's a bunch of CAN LOW faults on various modules. I'm guessing there's either a faulty module on the bus or it's the battery.
Did you go above 88mph recently ?

Properly looking over the error codes now:
A559
E104
A4EA
A4F2
D904
A0C1
C904
D944
D947
E584
Most are CAN Bus related but A559 (power loss to instrument cluster) and A0C1 (Short circuit or signal interruption) would suggest a battery issue.
Drive your car otherwise if you are lucky to have a garage use a small power supply if it stays for weeks parked up.
Or lend me the car for a few weeks I will get the battery charged up free of charge :-)
You're truly a selfless and generous person. But no.
Have you run an energy diagnosis on the battery through DIS? I just changed my battery over the weekend as it was starting to,give out a lot more frequently. I was trickle charging it when I got home at the weekend every now & again but the short journeys to work was killing it.
If you want to do the energy diagnosis just give me a shout, I can be found on Dublin's south side sometimes!
