In the TD5 D2, the heater circuit is the only reliable circuit in which to fit such a unit so all I can think is that your unit is unsuitable for such use. Maybe a different brand with larger diameter pipework might work better.

I simply replaced the metal section of pipe between the top radiator hose and the heater with the twine heat exchanger - no need to cut any heater hoses and I can easily return everything to standard by refitting the pipe section if necessary. I did need to reshape the turbo heat shield to enable the heat exchanger to sit neatly in place of the pipe.
Unfortunately this is all a bit off topic and not much help in regard to the original enquiry regarding the D3.
I tried a Twine heat exchanger as well, thinking it could have been the exchanger, that didn't work either, I borrowed my mates Twine out of his Cruiser and we spent 3 hrs trying it to no avail.
Don't forget the D2 has climate control, I'm thinking this could be the problem, also I had the Helton working perfectly on the Explorer, so there's no reason why it shouldn't work in the Disco.
I don't know, if anyone can show me that it works then I'll put it back in, because they are a great way to have a shower, I used to use the one in the Explorer all the time.
