On the last couple of days, I have noticed small puddleof Anti Freeze Liquid under my car and yesterday the Light went On for Low Anti Freeze Fluid. So I looked under the Hood for the common places and Water Pump, Radiator Looked Fine. Thermostat looked also fine. I noticed a little trickle from the back of the engine. I looked with a mirror and I could not see the Source of the Leak.

Does anyone have any suggestions to where to look back there? The Worst I can think off is cracked block but I am not overheating and I can drive fine. I wonder if this is common problem .

 

Check around the oil cooler or under the intake manifold on the block

 

I was searching for the Leak until I ran into other problems. At the same time I was changing my Oil and when I went to put the plug back in, the Drain Plug Washer Broke on me. So I have to order a new one and until I get that, I can not run the engine.

I have a funny feeling it is the Cylinder Cooling Flange in the back of the Engine. Part#058121132 I read somewhere that is a common problem with Leaks. My Car will be down for a while until I get the freaking Oil Plug.

 

You can get a washer from the dealer for free!

 

I have the same leak from the back of the motor! i cannot see anything leaking though... :/

 

I have to work. Audi Dealer is 10 Miles in the opposite Direction for me.

As far as the Leak to the Flange, there is a Hose that goes from Heater Core to Flange that also has to be replaced. I ordered the parts but want to wait until I get the oil plug and run the engine for a while and snoop around the back. I really want to see where it is leaking. Kind of hard looking for leaks when it is raining hard too.
