    Audi recommends G12 spec, which is red/pink. I believe problems only occur when two different types are mixed but don't quote me on that. Go spend a tenner on 5 litres of pink stuff and 5 litres of de-ionized water and mix 50-50 for peace of mind. That leaves you another 5 litres of mix for any future coolant issues.

    A quick google suggests mixing different types can form a jelly-like substance so not ideal. Give the system a flush and use OEM recommended.

    Current stuff is G13 and the best to use.

    Should be fine temporarily. Just make sure it gets a proper flush when it's changed.

    Audi have failed to send me an updated user manual with this new spec...same with the oil ;)

    Haha, i'm sure you already know, products develop over time! - G12+ & G12++ has been removed from stock at my local dealerships.

    Also - I don't drive the car as intended in the manual, therefore need a different oil!
    The manual also stated to service the car on a long-life schedule - meaning the cams wore out, so I dont take my manual as gospel :)

    I've noticed that my coolant has dropped a bit (not much), I'm hoping it's due to warm weather rather than a leak. Anyway I've bought some G13 and wanted to check it's OK to mix with the G12 that's already in there?

    A little more worrying is that my marker float seems to have disappeared. I know it's not essential for operation but I just hope it's not sitting somewhere it shouldn't be and causing a blockage.

    Anyone else lost their float?
