    well as of now it seems to have fixed itself which makes it very difficult to track the problem and i need to sort it as the car is for sale dont want to sell a car with a problem lol

    I had this happen on my car a while ago...
    Turned out to be the door pin switch. Mine was passenger side. The interia light flashing was a way of the car telling you that its not right,
    If you lock the car with the problem does the alarm go off? If it does and you have vag com it will tell you which sensor triggered it.
    Also... when it does it... see if the red or white light that are on the doors are flashing, If its a door sensor that door will have the flashing lights to match the interia light.

    To fix this there are 2 routes... one is a new switch but this is expensive as its part of the door lock. the other is ... adjust the door striker slightly so the switch makes full contact or clean the switch with wd40 and make sure its moving freely.

    paul that makes sense because everynow and again the screen in the instrument cluster says a door is open when its not to sort that for a short time i just have to open the drivers door then close it again so i presume it will be the drivers switch

    It's the drivers door microswitch, common failiure when its warmer. The problem is the microswitch isn't available on its own so you have to buy a whole door lock mechanism @ £90 ish and then fit that to cure it

    Do a search on microswitch, theres loads of info on it and quite recently 'dancarpy' did a decent write up on how to resolve this with some pics too :)
