Don't turn the A/C off as that is acting in reverse as a heater and 'pumping' heat from the warm air at the back of the radiator into the cabin. My A/C in the office can be used to heat and even in these 1degC outdoor temps, it manages to find heat within that to 'pump' inside.
It sounds at though something is not functioning correctly. Try running the blowers at a slower speed and on recirculate.

Car a/c doesnt usually have this reverse mode, its cooling only.
Diesels heat up more slowly than petrols, but the thermostat should ensure it gets there in the end.
Check out the temp of the heater hoses (two rubber hoses in the engine compt. that go into the cabin and feed the heater matrix). You may have some kind of airlock or problem with the climate that means it is diluting the hot air with cold air.
With engine up to temp (15 mins driving) the hoses should be at 80 degrees or so.

SOunds very much like a problem with the cooling system- airlock, thermostat, loss of coolant etc.

Diesels do take an age to reach operating temperature, the VW PD units are slow heaters, taking 20 minutes to reach operatiing temperature. The climate control does not work (in heating mode) until it has.
Where did you measure the temperature output of the heat?

Got to disagree AE - the PD does take 20 minutes to warm up but mine does start putting out warm air quite quickly, usually within 5 minutes. Really hot air does need a hot engine though.

We placed the thermometers in the cabin, one on the dash where the Sat Nav screen is, the other near the gear leaver console.

Many Thanks for the suggestion, what is the best method for measuring the temperature of the hoses?

We have some little infra red temp measuring devices in the workshop, but you could probably judge by hand. The heater hoses should be too hot to comfortably grip.

Penultimate parapgraph in this report suggests you have a problem: www.sovereign-publications.com/images/Auto/Honda%20(Kenichi%20Nagahire).pdf
This is excellent, I can't thank you enough for identifying this material. I will willingly quote this to honda if I feel they are just trying to flannel me.
I don't understand why neither the dealer nor Honda appear to want to take this complaint seriously - especially given the 'boasting' that Mr Nagahire has done.
It is very dissapointing that the dealer has not thought it worth while exploring some of the suggestions in the reply's I have had to my posting. Nearly as dissapointing as to the fact that I am still waiting on a response from Honda UK - after two weeks !! They did appologise in response to my second e-mail and promised contact the next day - that was a week ago!!
