HDC System warning fault?
I started the car this morning and got this message, started the car and it went and the car was fine.
Did a little searching on here and it seems it could be a battery fault so I entered the 'secret' menu and after a 100 mile journey, when the car was at idle, the battery was showing 13.5v.
Does this sound about right or should it be higher? I can never remember what's good and bad with voltage.

I'm no expert (they will be along shortly hopefully) - but it could be your battery, or it could be the alternator on it's last legs, and if/when the alternator finally goes it can take the battery with it (guess how I know )...............I think the preferred method of testing is with a decent multimeter measuring the battery voltage with the engine off, and then with it running - should be around 14.6v with it running IIRC.Jim

Cheers, it had an alternator last year before I got it I think.
I've been suspecting the battery for a while now also

You'll be wanting one of these then - it's what everyone on here suggests, and it's what I'm about to order......to replace exactly the same one that my knackererd alternator has just cooked
Get some proper readings with a multimeter and go from there. Was the alternator an OE Denso/LR or aftermarket?

I'm not sure what standard to be honest, I suspect pattern part as it was maintained at an Indy apparently.
I have breakdown warranty with the AA so when the battery goes they can have the joy of fitting etc for me and replacing. Much easier in the pocket

Very true but batteries are half the price through the warranty
