Yesterday ( with a small audience of Elvis & Paddywac) i stripped it down and replaced the three sensors/thermal switches, glowplug and made sure the external connectors were all clean. I was very suprised on looking inside the heater, how clean it was, like new. After putting it back together and refitting it back under the van, i turned it on to find there was no heat. The only thing i could think of was the new plug electrode gap was to big (my previous thread) or there was an air lock in the fuel line. The gap was shortened to about the size for a normal spark plug ( hopefully i will find out what it should be) and refitted it, still no heat.
This morning i thought i would give it a serious coat of looking at then check the fuel line and plug again. I flashed it up just to make sure and would you believe it i had constant heat. I carried out futher tests during the day and it's a runner.


For all those B2L Eberspacher owners out there with faulty heaters, look in the Wiki and follow Irishdavids advice. I had been planning to get a propex, as my heater has never worked properly since i have had it. For the sake of buying a set of car ramps and some new sensors/switches, at less than £40, i now have a good heater.
Big thanks to Irishdavid(especially), Ringo, LHD, T'Onion ,Mocki and Spike for advise.
