    Had the dreaded "stop engine and check coolant level" message in the DIS this morning. Managed to get home after a brief check to ensure there was still some water in the expansion tank, and drove to the dealer at lunchtime. Thankfully they agreed to look at it this afternoon, and have just called to say it needs a new pump, but as this won't be with them until tomorrow they need to keep the car over night. The car has done just shy of 17000 miles.

    There have been one or two mentions of water pump replacements on here - it looks like this could turn into a common fault.

    Is it a particular engine, or does it affect all of them? I've not heard about this problem before.

    I might be jumping the gun a little in predicting a common fault, but TreborA4 reported a problem with his 2.0 TDI 3 weeks ago in the thread "Water pump leaking!", and I've seen one or two items in Google. I thought I'd seen others here too, but I couldn't find them with a very quick attempt at a search. As I've got a 1.8 TFSI I don't see a common factor.

    Example: 2012 Audi A3 1.6tdi coolant loss (1.6 TDI and 1.8 TFSI)

    I had low coolant warning a while ago. I've got the 1.8tfsi. Not sure if anything was changed, Audi reading were sketchy on the details, but they had it in for 3 days

    I had water pump issues with my previous 8P A3 and Mk6 GTI. Seems to be a weak point of VAG cars.

    My car is drinking G13 coolant.....

    [​IMG]



    My S3 has just done around 4k miles, and the coolant expansion bottle has gone from MAX to MIN in that time.

    Crewe Audi have booked it in for next week, and given me FOC a bottle of G13 to tide me over till then!

    Will report back.

    Same issue 2 weeks ago, suddenly the coolant was under the MIN when the alert turns on. Went to Audi and changed the Water Pump applying warranty. They said it was preventive because the water pump was ok. At least they have the piece in stock and it was ready the next day.
    Forgot: my S3 just have 2,400 Kms

    That's interesting. Never heard of a dealer changing a water pump, if it wasn't leaking !!

    Wonder if there is a TSB bout it being a known issue ?

    Car is back, with no fault found.
    No visible signs of leaks, undertray is clean.
    Pressure tested, left pressurised overnight, no loss of pressure.
    Car returned to me, asking me to monitor the situation.

    I'm at a loss as to where this coolant has gone.

    I was like you, even they took out the plastic shield under in front of me, there was not sign of leaking on it. I still thinking they donĀ“t fill right the coolant when it was new.

    One of the tests Audi UK Technical got my dealer to do was:

    Ensure coolant at correct level
    Pressure test - run car
    Pressure test - leave overnight
    Observe for pressure loss in the morning
    Start car - listen for misfire/s

    Mine had a slight loss of pressure overnight, but didn't misfire in the morning. So they returned the car to me, asking me to monitor for any further coolant loss.

    My leak was caused by the metal pipe that runs across the top of the radiator approx 18 to 24 inches long, it was on back order but has now been replaced.
