I like your spot, I wish I have 2, one like yours and the other one like mine near sliding door.

I remember reading that someone had cut vents into their plastic hatch access door (in seat base), but can't find reference to it. I have a swivel on top the base, so there's not much air flow. Anyone tried this and had it look nice? I can't see taking an exacto knife to this and it looking pretty?

Recently I talked to Eberspacher, MB, and VW (Crafter) about availability of this access door with vent holes, no success. Just bought a spare door from MB for $5 to experiment with cutting holes or slots. I was thinking about doing CNC which still could be a good option but mounting on the table could be a problem. I will show this door to Hein and see if CNC is possible.

I would be happy to machine some slots in that door.
How many people want one?
what is the part number?

I just pulled the foam cap thing that is under seat base, this seams to allow plenty of air flow to the unit

That sounds very easy... I was thinking the same thing... maybe more noise?

I don't get it.
You want to put a diesel (hot and smelly) fired heater under the passenger seat in your Sprinter?
Where is this device going to get it's intake of combustion air, and where will it exhaust all the
fumes and CO?
Or are you simply putting a heat exchanger under the seat, and the hot smelly part goes outside
the cab and gets plumbed with hot water hoses?
The foam "cap" on the seat base is there to keep the cold air (inside the seat box as it's bottom is
the stamped sheet metal floor of the Sprinter's cab) down in the seat box...well, down in the seat box.
Might also cut a slight bit of noise coming up through the floor.

Espar heaters are designed to be mounted inside vehicles including places as under seats. Combustion air is drawn in and exhaust gasses passed out via small hoses that exit from the bottom of the heaters and go down through the floor. No fumes are present in the vehicle.

Thank you Hein.

Not slotted part is A 9065450003, made in Germany, must be old part because the package has printed DaimlerChrysler AG.

I prefer to keep the foam sheet in place. I don't know what the exact reasons were for Eberspacher's engineers to design the slotted door but as mentioned earlier sound reduction and thermal block likely were on their list.
http://www.esparofmichigan.com/techs...%2006-2007.pdf

In my case the outlet is between the seats so having intake from the colder right side of the passenger seat is likely a good air circulation flow. I removed the door and would like to cover the hole.

To moderator It seems that installations of Espar D2s are common and it would be nice to have a centralized place to post D2 installation links or threads. Searching not always brings good results if right words are not used.
