Any Eberspacher experts on here?

I've got an airtronic D2 which I installed myself, and it's worked flawlessly since fitment.

I used a dip tube for the fuel pickup and stopped it about 20mm shoft of the bottom of the tank, so it can't run the tank dry or suck up any muck. If the fuel light is on, the heater gnerally won't work.

I tried to put it on last week and the fuel level must have been too low as it didn't work. I put some fuel in, bled the fuel line to the D2 out and it worked a treat. It was rearing away yesterday morning no problem, defrosted hte van a treat. I went out for lunch and put it on so it'd still be warm when we got back to the van, but the heater wasn't running...strange.

Just been laid under it in the snow there, no bubbles in the fuel line, bled it anyway, fuel there, pump is working fine. But here's the symptoms.

I'll tun it on. it'll click. then a wisp of smoke comes ouf the exhaust, as expected, coupled with the fan running "very" slowly, but I hear no clicks from the fuel pump at all, and after a few seconds the smoke and fan stop and it does nothing. I've tried turning it off, then back on to see if it'll start (as that sometimes sorts it out) but no, same thing every time.

huh?

one thing i did notice when i pulled the fuel pipe off to bleed it was that it wasn't pushed fully home onto the unit. could it have got wet and drawn water in? if so, what are the consequences of this and what do i need to clean out/replace?

TIA.

thanks, I'd just read that on a site i googled, but i don't know where the glow pin, vent hole or screen is located on the unit?

arse! typical, it's underneath the van, so i can't fix it in this weather, but i need it in this weather.....G

Tried that, does the same thing. I tried manually priming the pump again but with it attached to the unit this time, and could see a fee more bubbles in the line Sony got all those out. I got a bit more smoke but still did the same thing.

A mate who services them for a living is going to have a look tomorrow I hope.

It's an 801 controller, no faults stored on it.

It's powered off my leisure batteries, will check voltage but they're usually fine. However, it did struggle to start off the main battery the other day...so you might be onto something. I'll see what voltage I got at the plug.

i work on these.remove cover and glow plug grommet(brown and white wires)down the side of glow plug body theres a small 2mm hole that gets carbon build up,clean out with a bent wire.this is your air supply on start up.if thats no good remove heater and strip the green combustion gasket will be broken up replace rebuild but check temp sensor resistance.eberspacher not helpfull but search espar heaters(usa eberspacher)will really help with checks.word of warning inlet and exhaust pipes very fragile so be carefull.good luck
