Has anybody had problems with these heaters cokeing up whilst running on red diesel?
Eberspacher airtronic heaters

Not specifically but they are recommended to be serviced periodically and if you run on low setting for a long period they do tend to coke up a bit. I have found that adding "fuel set" to the fuel improves combustion a bit and helps to minimise the problem. You might try it.
Apart from early electrical problem, ours was fitted sometime (I think) in early 2002 and has worked fine. It quickly heats up our saloon.
Although the battery drainage is quite light, I sometimes wonder if we should have installed a cheaper unit, say charcoal or paraffin.

It's a new one on me. Mine is 3 years old and works perfectly.

Had no problems with mine, but I filter all the fuel as I put it into the tank and use fuel set. /forums/images/graemlins/cool.gif (although Soltron is supposed to be at least as good, fuel set is actually authorised by Eberspacher).

Best way off cleaning a coked up burner is to run on neat paraffin so the tech man at eberspacher advised me. Fuel aditives can cause a problem with the system. "Fuelset" is the only one approved by Eberspacher, but that is because it is the only one they have tested without any problem. I have a 2 year old Airtronic these newer burners use a ceramic glowpin for ignition as opposed to the glowplugs on earlier heater's, it was this glowpin that carboned up with me possibly due to fuel addative.
Good luck, keep warm

Oh well. Mine is now 18 years old, and although I moan frequently about Eberspacher for various things (especially spares prices), coking up has never been a problem. Runs on normal Red from the main tank. I have 'de-coked' it twice while stripping it for other reasons. Eberspacher point-blank refused to tell me what to use 'for health and safety reasons' so had to make my own guesses as to suitable solvents.

Yes. I've had to de-coke my D2 twice now. Early symptoms are failure to start first time. The unit does an auto-restart and then runs OK. Only when its really blocked up does it fail to fire at all. First items to replace are the glow pin screen and metering pump filter - do this annually if not before. If this doesn't fix the problem then a de-coke is needed. The problem is the "swirl ports" at the back of the combustion chamber get clogged which causes the flame to blow-out. De-coke is easy. Remove combustion chamber, put it in a bath of diesel (white) overnight, then flush out the disolved carbon and allow to dry before re-fitting.

My heater is 17 months old, it packed up through coking after 7 months,
was sorted under warranty only to be told that it should only be run on EN590 fuel (which I believe is white road diesel) it has now run for another 6 months untill it has coked up again. Not forgetting that these periods include summer time when the heater is not used. I recon that it is not fit for the purpose it was purchased for. so I am trying to collect as much info of other peoples problems as possible. Thanks for your reply. Dave
