Well one of the dreaded CRD cancers took no exception to my patrol. It seems that way anyway ...
The same spot I reported a coolant leak a while back, now holds a dried out toothpaste like green/white residue. This if I'm not mistaken is coolant mixing with oil.

Where it's leaking from is very hard to tell. I'm not that mechanically minded when it comes to this engine's anatomy. It seemed to have happened over the last 2-3 days. I had a couple of 45 minutes trips during these days in 34+ weather with air-con running. Maybe it's something to do with that I don't know. Engine didn't overheat or anything it's sat at it's usual half way mark.

I checked the oil (dip stick) and it's nice and clean no trace of any milkyness. Likewise with coolant I checked overflow bottles as well as in the radiator all seems fine and well topped up. One of my neighbours is a mechanic and although he doesn't work with diesels he doesn't believe it's oil/coolant as it wouldn't be this dry and crusty, although he can't say exactly what it could be.

Can somebody confirm that is the air-con compressor in the photo. Does that have anything in it that could leak out??

I'm not hoping somebody here has another idea about what it could be, but at this stage it's not looking good.
