Leak from steer? Or nowhere ?

TandEadapt was serviced just before our arrival in Alicante. The gold puddle was a surprise I was not startled by though. I have two theories for this puddle. 1. Being the steering hydrolics are leaking again. The other, 2. Being water spilt out from the sea cock when they tested the battery, but that's naff.

So to eliminate the possibilities we've cleaned it up and put paper down in the other wise emaculate engine room compartment to indicate where the leak is coming from. Got to be from somewhere.
