Only bought the car so made no changes myself. Just been sticking off the small list of thinks to put right.
I'll discount the batt and do the other things you said and see what happens but I think I'll remove the Dump valve to be sure when I get a new original recirculating one. I was talking to a lad on rsoc by phone there and he is convinced its what is causing it. Had the same issues himself.
Thanks lads. I'll keep you posted.
