Hi, trying to get at this , but want to know more about what part(s) are leaking.

It's in front of the exhaust coming out of manifold.
think egr coolent? Hose attached to metal with worm clamp
about 2 inches?.
Vision this looking from the ground up. Looks hard to get at.

This is on the passender side of left hand drive USA vehicle.

Hope this does not sound to weird. :?:

I assume you have confirmed it's antifreeze (tastes sweet). If so see pic 6 at viewtopic.php?f=98&t=74594 . It's not the EGR cooler as that's on the other side. Most likely a coolant hose to/from the water pump, bypass, or oil cooler. Could be leaky water pump impeller shaft but on the CRD design I'd expect that leak to show on the bottom front of the engine coming out from behind the inner timing belt cover.

You may need to rinse things off, add UV dye to the coolant, drive for a few days, park in a sheltered not sunny area, and look for the specific point with a UV light. It's not at all uncommon for OEM coolant line spring clamps to slowly unspring and cause small leaks.

Ok, have tigthened all the clamps and changed some.
Replaced the coolant cap with new one.

Hose clamps on the reserve tank are all changed some did not have a clamp the overflow hose did not have clamps on it above or below, and new cap.

Fluid leaks after highway driving when parked but only
after 15 minutes of sitting does it start to leak. :?: :banghead:
Believe the bottom 1 inch hose near the front of tank.
Tightened this one again when it was hot. After leak was prsent again yesterday.

Thanks, Layback

Of all the things a brand new clamp was bad casuing the leak again.
Changed out and pressur etested cold and it held pressure so hopefully this was it.
