Default Coolant leaking by drivers side

I have had a slow coolant leak for a while. But recently it has been leaking faster. Where I was only adding coolant every 2 weeks its now every 2 days.

I cannot pinpoint where it is coming from but the coolant is dripping down the drivers side of the trasmission right behind the engine.

Any ideas? I thought it may be the aux coolant pump but all the write ups I am reading are saying that leak shows up on the passenger side.

Interesting. Im diagnosing a coolant leak on the drivers side as well but mine drips on the front of the motor. You may also want to check the front too as it may be getting blown back towards the trans or traveling towards the back on something. I haven't figured mine out yet.

On the 2.7t, you can aim a small flashlight through the thicket of stuff at the front of the engine and see a tiny bit of the top. If there's any pink, it's the aux pump.
There's good instructions here somewhere. Not a particularly hard job, but a lot of dis/reconnection--a little labelling and good organization helps. And you'll wonder what German engineer put such a failure-prone pump in there!

Well I'll take a look and try to see it again. But I think I will go ahead an order that aux pump. I don't think I have ever heard the aux pump running so I think its broken anyway.

Nothing on the 2.8. They are in a different location and they don't leak.

On the 2.7 the plastic cracks.

I doubt you'll hear it even if you replace it. It rarely gets hot enough for that pump to run.

unless you do the s4 mod and switch the activatio switch to a lower temperature , then it runs like a built in turbo timer
