Another wee problem with my Disco is that it's developed a case of asthma when accelerating. It doesn't always happen, but often enough to be very irritating. I found that if I slip into neutral and rev the balls off it, it seems to be OK again, especially when it's hot. I changed the (admittedly very claggy) fuel filter when it first happened, but it made no difference. Was the filter change too late and there's crud in the fuel lines beyond the filter, or is there another explanation for this phenomenon? Again many thanks for any and all help/suggestions.

Find / make a friend who has diagnostics and get it checked out.

Cheers

+1 for making friends with a NanoCom/HawkEye owner so you can get fault codes read, when was the last time that air & oil filters were changed?

I just found that the big air tube to the turbo had been left loose at both ends, presumably by my dear local garage, and when I checked the air filter, it had been fitted upside down and consequently was a mangled wreck. I've tightened up the jube clips on the air tube and put in another new air filter after sucking out the dry leaves in the bottom of the filter box and mesh filter above the air filter at the head of the air tube. The car runs an awful lot better now, not surprisingly, but hiccoughs now at higher revs, rather than being asthmatic. I just hope that pulverised crud hasn't got somewhere it shouldn't and is tickling the back of the old girl's throat.
