[s-cars] coolant leak

[Manuel Sanchez]

Martin,

I had that little section of hose, under the coolant manifold but  
above the after run pump spring a leak just after I parked the car  
after a run session at the track. That was the good news, the bad was  
having to try to source the part as well as accessing the hose, as  
you know it's buried in there.

Fortunately you can get a ratchet in there with a couple of  
extensions for gear driven clamps. If your current clamps are  
oriented just right, you should be able to get to it surprisingly  
easily. I got a ride to a FLAPS and just bought a few different size  
hoses that were close. Back at the track I fitted the tightest one.  
After returning from the event I went to the dealer and after 3  
attempts they never were able to find the "correct" hose for an OE  
replacement, even though I brought them the old hose, with the Audi  
PN stamped on it (one or 2 digits were admittedly tough to read).

If you or anyone end up, or anyone else has ever sourced this little  
hose, I'd love to know what part number you ended up using as well as  
where you got it from becuase I'd then try to pick up a replacement  
hose from there to stuff in the glove box.

Regards,

Manny
