2002 A4 1.8T Coolant Level Low
Hello everyone. It's me again, with yet another problem with my least
favorite car of all time!
My coolant level light went on the dash this morning. I had driven
the engine hot, so I brought it home and checked the level. When hot,
the level was two or three inches below the "min" line.
So I got out some engine coolant (the red stuff) mixed it 1:1 with
water, and added it in. However, when I opened up the engine coolant
compartment, the liquid must have still been pretty warm, so it kind
of boiled and bubbled a bit. As the air seeped in and the screw top
came off, the level rose back up to the exact right level.
Not sure what to do at this point, so I waited for the car to cool
completely. Once I did, the level dropped back down again, but not
all the way to where it was when I first checked it. Maybe just an
inch or two below the "min" line.
At this point, I added in my coolant mix up to the proper fill line
and re-capped the tank. I haven't driven it since.
There are no leaks coming through to the ground, although it does seem
like there is a bit of liquid collecting underneath the passenger side
of the radiator compartment -- not in front of the radiator, but on
the engine side of the radiator.
So what's the prognosis? I know I should take it in, but I have to
get to the airport tomorrow morning. I'm hoping the top off holds for
a bit and will be fine in long-term parking for 6 days.
By the way, this is a 2002 A4 1.8T with about 44,000 miles on it. It
has been in the shop (in just the last six months) for the following:
New thermostat, two vacuum hoses, air-conditioner that wouldn't blow
cold air, and all the regular maintenance. And, of course, the car
has also developed the clunking noise under the driver side wheel that
I am talking about in another thread. This should not be happening to
a car that is under 50,000 miles.
Anyone in the market for a used car?

If there's a slow leak, it will be less pronounced when the car is not
running. Just check when you return to make sure there's not a large pink
puddle under your car. There are severalpossibilities for the source:
cracked coolant recovery tank ( the thing you opened up to add coolant),
leaking radiator (I had to replace mine at 65K miles for about $700),
leaking hose, leaking heater core (but then you'd likely smell coolant in
the passenger cabin), leaking temperature sender, cracked engine block (but
then you'd be seeing some whitish smoke out the tailpipe.)

I know some of the responses to your woes have been a tad defensive but I am
one who agrees with you on the reliability of that vintage of A4 (I have a
98.) Somone earlier lauded the sophisticated Audi engineering but as an
engineer myself who has worked in the automotive industry, I can assure you
that "sophisticated engineering" requires attention to longevity of
components and the overall system and that's something that VW/Audi has
taken a long time to learn if it yet has. Hyundais OTOH were pretty crappy
when they first arrived on our shores but the improvement in those cars has
been nothing short of amazing.

If there's a slow leak, it will be less pronounced when the car is not
running. Just check when you return to make sure there's not a large pink
puddle under your car. There are severalpossibilities for the source:
cracked coolant recovery tank ( the thing you opened up to add coolant),
leaking radiator (I had to replace mine at 65K miles for about $700),
leaking hose, leaking heater core (but then you'd likely smell coolant in
the passenger cabin), leaking temperature sender, cracked engine block (but
then you'd be seeing some whitish smoke out the tailpipe.)

I know some of the responses to your woes have been a tad defensive but I am
one who agrees with you on the reliability of that vintage of A4 (I have a
98.) Somone earlier lauded the sophisticated Audi engineering but as an
engineer myself who has worked in the automotive industry, I can assure you
that "sophisticated engineering" requires attention to longevity of
components and the overall system and that's something that VW/Audi has
taken a long time to learn if it yet has. Hyundais OTOH were pretty crappy
when they first arrived on our shores but the improvement in those cars has
been nothing short of amazing.

With good [high] pressure in the coolant system, it's not too much
to worry about. You got it with the new thermostat ... higher
temp, higher pressure.
Sounds more like a small leak around the water pump axle, may happen
when it's time to change the pump. I drove mine for several months
since it started leaking... Until it was time to change timing belt,
then - I replaced both timing belt and water pump.

Re: 2002 A4 1.8T Coolant Level Low
Could it be that coolant pipe on the rear of the cylinder head?
Look at the oil cooler sometimes those hoses leak.
That is IF you have a leak. Usually you will see some red cruddy looking
coolant residue at the leak.
Maybe the thermostat has the leak. Why was that changed?
