    Been to look at a 51 plate 2.5tdi SE today and all looked good but when i checked the coolant header tank the coolant resembled a milky tea colour and on rubbing it between my fingers it seemed a little greasy, the arrogant unhelpful bloke at the dealership reckoned there was nothing wrong with it and that was the antifreeze, trouble is i dont know what colour the Audi coolant/antifreeze is as i'm used to looking at the pink G12 in VW's.

    Was he correct and milky Tea is the correct colour or was i right to walk away?

    TIA

    I'd walk away myself. The milkyness is caused by oil mixing with the water so at a guess it has had or starting to develop a head gasket failure.

    Should be red, no other colours involved.

    Should be red if you're using G12 or pink for G12+

    Your gut feeling saved you. It should be pink as per G12 Plus, Its possible that a good flush would fix it as it could be mixed coolant. Ie non G12 and G12 from the previous owner
