I've spotted coolant on the top of the water pump housing on my 2002 P38. I just can't get in to feel the exact place from where it's leaking. It's not much and I'd say it definately was coolant as it's recently been filled with new pink anti freeze. It's directly beneath the ac compressor. I've looked on the download manual and I think I can make out a bolted flange where the tophose connecting tube bolts to the heads. Please say that that's the only thing it could be. I've done a search and the only relevant contribution was a rad leak possibly being fanned back. It's a brand new rad and there's only a localised spot of coolant. Hope you can help with a diagnosis.
thanks and regards P.S
