Sorry, hadn't seen any replies before today...
Try leaving the disc in for a few hours, can't harm anything - post on here so others know whether it's good to go or not.
And as for servicing, we do hear of the odd garage/guy here and there, but like Sharky (Hi matey) say's AAA seem to get the best reviews, non bias as I haven't been yet, but like you my contracts are about up so tell Gordon I sent you and maybe he'll give me that extra discount for referrals, lol
All the best
