    Just a heads up to the Forum.
    Got a low coolant warning on my car last week, checked it out and was below MIN level on coolant tank.

    Had a good look in engine bay and found evidence of a leak but could not find exact location. Topped-up coolant tank, and over the course of several hours the level dropped again.
    Took it straight to dealer and they found that the coolant pump was leaking.
    They have now replaced the pump and no more issues so far.

    My daughter also has a 2019 RS3, have checked her one out and her car also has a leak from exact same area, her car is now with the dealer also getting coolant pump replaced.
    Both cars have only 4000 miles from new.

    Let’s hope this not an ongoing issue with the 2019 models.
    Has anyone else on the forum had the same issue?

    On both our cars we had confirmed evidence of coolant leaking.
    Apart from the coolant level dropping over a few hours there was also coolant on our driveway where both cars are parked.

    Wasn't suggesting it didn't have a leak, just very strange that there is/was an issue on many RS3. At least yours is sorted now though :D

    I do hope you have some good security, you'll be a beacon of light for lots of people with 2 of the beasts parked up! I'm paranoid enough with one!

    Yes, I am the same but have CCTV on them but if they want them they will get them.

    Just the way our society is these days.

    So that’s three failed Coolant water pumps so far on here.
    There has to be a manufacturing defect on the 2019 models. I wonder if there is potential for a recall on these models?

    Yes, fortunately once the level drops below MIN on the Coolant Tank a warning light will appear on the Virtual Cockpit.

    I have not checked with dealer but having replaced my coolant pump did they just replace it with the same type & model? or have Audi changed the pump and only changing them when a loss of coolant is found?

    So this affects the cars with the OPF only?

    I am not sure, my Audi dealer said they had not had any in until mine was booked in.

    No, my Audi mechanic replaced coolant pump on pre OPF RS3 (30000 km) a week before mine.

    I've done a few 2019 models now, but earlier models don't seem affected on the same scale.

    Looks like a faulty seal could be to blame, it's no problem though the leak is very minimal and easy to spot, so not like the car just dumps all it's coolant in one go.

    Thanks for given an actual answer what the cause is, will put some owners at ease at least that maybe effected.

    When mine was in for coolant loss investigation all I got from the technician was that the leak was coming directly out of the pump, no other info was given.
    Suspect it was a faulty seal within the pump but cannot confirm that.

    Once the coolant drops in the reservoir it’ll trigger the level sensor so you’ll know then something is amiss.
    If this happens check the undertray area and just under the water pump area for signs of staining / moisture.

    Don’t automatically assume a failing pump though, the factory filling isn’t great sometimes and over a period the level can drop naturally, so top up accordingly if no leak is evident.

    I would expect most owners who check their cars on a regular basis would spot anything amiss anyway.

    Oh and on the check your car thing, the Pirelli tyre inner edge wear can be spotted by putting full lock on and getting down on the floor with a torch, you can pretty much view half the tyre inner edge.

    Good explanation, my first indication was the warning light on the Virtual Cockpit, even though I check engine bay on a regular basis.
    There were no initial signs of leakage on the lower trays prior to the warning light appearing, but on opening the bonnet following the warning light there was lots of coolant sitting in the lower tray and signs of ‘dried-up’ coolant.
    So I suspect the coolant had been leaking very slightly but with no evidence on the tray, but then the seal must have completely failed hence the warning light.

    Just flagged up on mine too, checked and it’s a touch below minimum, taking it to dealers tomorrow to get them to top it up and book it in, assuming it was at max when I bought it it’s done 3500 ml to reach min level.
    Went to Halfords to get some to top it up and the said they don’t sell it for 19 plate rs3, dunno how true that is, told me it’s something I can only get from Audi direct?

    Just tell them you are aware of a water pump leak issue, they should check for the leak and top up accordingly, if it’s just coolant settling down.

    Incorrect info from Halfords (as usual).
    The Audi owners manual has the details of which type of coolant is required, don’t use anything else, for emergency top-up use some distilled water if coolant not available.

    I read the manual when I got home and found it was G13, they didn’t have this in Halfords, went to the dealers to see if they had any lay about on the off chance but as it was Sunday and no mechanics in none he could lay his hands on.
    The cars packed up for the night so it will be took back down in the morning, only 3 mile away, gonna make sure they give me enough coolant to keep it topped up till it goes in so I’m not dipping into my own pocket
