Thanks Folks
My dealer has told me that they will only fix it under warranty once, after that I have to pay!! Dealer is W Livingston in Hamilton, Scotland, they used to give great service but they have gone a bit "fu~k you" lately, changed management maybe? My other alternative is Arnold Clark in Edinburgh, but the car is out of warranty tomorrow and I'm going on holiday today, needs an MOT today, so I'm just going to sort it myself.
Thanks to muddyboots for the advice! I hadn't found the two screws under the lock cover. Just a lowly 1.2 but a reasonable amount of bodywork, switchgear, etc are the same so worth being a member here and talking to you guys with the souped up versions.
Cheers
