Newby with L322 and issues!

After owning a range rover classic a few years ago i purchased a well used L322 td6 last week and then towed my caravan to Cornwall. I've had to replace the blower resistor and reconnect all the interior lamps so far, but overall it appears ok. My only issue remaining is the fact that air susp. Inactive popped up as soon as I left home with the van on the back. Not on the bump stops, but control's inside are now inoperative. It worked ok until can was added! I wonder if I have a remaining fault, or whether it needs resetting to clear It? I have the software for my old BMW but I assume L322 speaks a different language. I am usually based in Warwickshire, but currently on holiday near St Austell in Cornwall. Would anyone be able to code read and reset locally for Me? What would be the best software to buy to avoid having to trouble others in the future? My final request is how to get sound from the necvox DVD player in the rear? Although silent Peppa pig is the best as far as we are concerned! Many thanks

welcome home, post this up the RROVER section there's plenty of l322 know-alls in there!!

Welcome aboard

I seem to recall that steering lock to lock can reset soft faults on the air suspension - but I may be wrong, as I am something of a Luddite when it comes to all this electronical nonsense

As above, post #2 - post in the RR section - plenty of folks with experience of all the usual suspects on the '322....
