Hi Christian. Could it be that your 2006 seat heaters are getting a little old and ineffectual? The reason I say this is that I have recently fitted a set of heated Puma seats in to my TD5 and they get at times a little uncomfortably hot...!

I am happy to check the resistance of each element if you want to compare them.

Apologies this took so long Christian. Actually hope you have sorted this by now.

Each pad (base or seat back) is showing a resistance of 3-4 ohms, so 6-8 ohms total measured from the connector under the seat base.

Not as easy to get to the connectors as I first thought, this was my solution;

Something that also occurred to the wife and i whilst chatting about the heated seats on a long cold journey the other week is that the heat emmited from the pads does seem to fluctuate. I assume that there must be a thermistor or thermocouple hiding away in the pads that controls the ouput and has an upper and lower limit. Perhaps this is the cause of your issues...
