We've just had this warning last week a month after LR topped ours up, it's not actually incorrect quality fluid but that's the only warning it can come up with, a Google search general consensus is the tank being overfilled, this is what we armed ourselves with last Friday when it went in, the dealer wasn't wearing it and advised us adblu crystallises and the injectors could have blocked, needless to say I wasn't wearing that, they had it 6 hours, did some 'things', very vague when pressed other than we reset the computer and the light went out, they initially said it would be a 96 quid diagnostic fee chargeable if they felt it wasn't of their doing, well because they didn't really know the cause we weren't charged a penny. Who replaced your engine? Might be that yours has been overfilled too

Adblu top up which to me was overfilled.

What's Eoly fluid?

If you have an adblu warning then it's adblu you need to look at but I would probably put my mortgage on it that it's not incorrect quality fluid, it's a catch all warming, like I said google searches come back with the tank being overfilled during top up, you've just had an engine replaced so it's likely your adblu was drained and topped up and thus overfilled
