    My 2.5tdi sometimes fluctuates between 700-800 rpm on startup. I hadnt noticed it until i did a cambelt change. Havent thought to anything about it but will be interested to hear what others have to say.

    get a new coolant sensor,that will get rid of eratic idle and give you better fuel consumption !
