Due to the higher ambient temperatures in the UK over the winter the pre heat function doesn't get anywhere near as much use as you will in Sweden so hopefully we won't get many issues.

According to the circuit diagram, the pre-post heating relay controller has 6 separate outlets, one for each glowplug, at least on the 2.7HDi. Does anyone know where the output 6 way plug on the relay controller is located, so that I can check the cold resistances of each of the glowplugs and see if/which any of the original 2008 glowplugs are still working.

In theory this will save me stripping down the top of the cylinder heads to access each glowplug??????

Many thanks
