L322 HDC Inactive and Air Suspension Inactive

Hi Guys,
Came out of work tonight and fired up the beast. Temp was reading -0.5C but as i went through the key positions the dreaded display pinged up "HDC Inactive" & "Air suspension inactive" . Reversed out the space and turned the car off, though i would have to do "lock to lock" to clear the air suspension as I still had the light on the hight display. As i turned the key back to start again i had no faults and she drove home fine.
Over the past few month i have every now and again had the HDC fault but its only just pinged up then cleared straight away.
Any ideas what could be the cause? Was she just off being left in the cold all day and had a mood swing or could there be something more to it?
Thanks in advance
Rob

Hi Rob,

I would suggest that your battery is on it's way out, don't forget how much your using it at this time of year and if your only doing shortish journey's it maybe is not getting the chance to fully recharge.
