D3 with a life of it’s own.
Guys
What a day to have car troubles.
Haven’t used the D3 for a couple of days so was surprised when the alarm went off this afternoon.
To cut a long story short, after investigation.
The car drives fine but I get loads of error messages.
Range change not available, parking brake fault, special programmes not available, etc etc.
But then the worst bit – when I turn it off and take the key out a few seconds later the Hazards start flashing, the sat nav screen goes on and off along with loads of other stuff, as if I’m turning the ignition on and off every couple of seconds.
Frequency is roughly what the hazards flash at as if they are controlling the ignition.
The only way to stop this happening is to disconnect the battery.
Battery is showing 12.3V disconnected.
No water in the footwells or fusebox that I can see.
Any ideas?
HELP

Blimy what a day for it indeed. Sounds serious however hopefully an easy answer. Brake light bulbs can cause a multitude of weird issues I beleive...

Charge your battery, no load should read 12.65 volts when fully charged, I believe!Faultmate Owner

Yep, just put the battery on charge for a couple of hours to see what happens.
Tried a hard reset and it made no difference.

Forgot to add that the central locking was also locking and unlocking.
The more I think about it the more I think it could be associated with a low battery voltage somehow.
12.2V does seam a bit low, although why it would have the effect it's having I don't know.
It's the first time the car hasn't been used for a couple of days in at least two years, so perhaps something is draining the battery.

Charge the battery until you are getting 12.70 volts that's a 100 % charge on a good battery Faultmate Owner

Sounds like the beginning of a CAN-BUS issue
Can be quite a long, involved job to track down the underlying issue...

A bit trivial, but a 100% charge on a good battery should be 13.2v My D3 Build Thread

So.
My battery charger brought the battery back up to 13.6V, put it back in and all seamed well.
Locked it back up and 10 mins later the alarm is going off.
With the key out of the ignition, or now even in the first position, everything is going on and off including the hazard lights, it's bonkers.
I'm also getting a Parking brake fault showing.
I'm beginning to think it might have some water in somewhere from all the heavy rain.
I've disconnected the +ve terminal of the battery and closed it all up but can't of course lock it.

Depends who you listen to
A typical battery has 6 cells, at "between 2v and 2.2v" per cell, depending upon type of battery, which is anything between 12 and 13.2v. A fairly big discrepancy. But as said, it's trivial, and depends who you listen to My D3 Build Thread

This is definately a CANBUS issue now. You need the isolate each part of the network in turn, and see which cures the fault. Due to the amount of rain, check in the transfer case ECU, behind the battery.

I have also seen EPB modules fail this way, though the car is usually running for a while before this happens...
