Faults on my D4: should I be worried?

Hi guys,

Finally got my D4 this past weekend and started playing with the IID tool this morning.

Picked up a bunch of fault codes, and one of them comes back after I cleared them.

Vehicle is going in for lower control arms in 2 weeks' time, so I have cleared the faults and will see if they come back by then.

Anything there I should be worried about?

Faults found:

Wouldnt be too concerned about those that dont re-appear. They may have been caused by low battery or odd circumstances which confused it a bit.

My XC70 Volvo used to have a similar code to the one that stays which was put down to a software incompatibility in an update it'd had at the dealer. It never caused any noticable issue and everything worked fine.

I wouldnt be too concerned personally.

As Biosbill says, could be caused by a low battery voltage. If you've got a DVM, it would be worth checking what voltage is across your battery - both with engine stopped and running. D4 MY14 XXV - RLD/IID BT

thanks.

Voltage when not running is 12.5V, not sure what it is when running.

The car was being worked on for lower control arms before I took delivery. If they disconnected the battery, could this be the cause? --
