Excellent presentation, ty

About how many hours of running until replacement of these filters is needed? Also, how often should I run my heater during the summer so the fuel filter doesn’t get gummed up?

I don't know how this video has so few views/likes. I've serviced my own d2 heater multiple times and this time around I'm getting white smoke billowing. I'm going to re-check the things described here. Best info I've found! Thanks so much! Please make more!

It was getting smoke and no start so I tore it down cleaned everything replace the ignitor and screen put new gaskets in it was 3.5 yrs old at the time worked about a week didn't see any visible smoke took right off sounded fine a week later no work I cleaned everything again right full of carbon new gaskets put it back together and today it stopped again looked in exhaust with scope its right full of carbon again any ideas where I'm going wrong

@@jeremyhanna3852 have you replaced the fuel filter? Enough anti-gel additives in fuel I’d expect?

[@jeremyhanna3852]

@Alex K it's fixed I replaced the hole burn chamber

@@jeremyhanna3852 thanks for letting me know. I’m thinking of replacing mine if cleaning with acetone brings no effect.

My control unit is held down by three screws, not one. And the screws are five point screws. Also the igniter is not attached as a separate piece, it’s attached to a hub that goes to the wire harness. I managed to unscrew the igniter, but the wires kept twisting since I could not detach the igniter from the hub. I successfully replaced the atomizer screen and reassembled everything. Would be nice if an updated video was available for the newer Airtronic D2 S2.

Good video. I’m having a different problem. The control unit screen is lit but blank. Just started doing this. Any idea?

Great job explaining the service

Where’s you source for the 12mm slotted socket?

[@ryanroads7748]

The socket can be reused...at least mine is.

Sadly this video isn’t much help as I have a Generation 2 D2. It requires a TE-Connectivity type removal tool to extract the glow plug pins out of the connector.
