The Eberspacher Airtronic M2 D4 is a diesel-fired air heater kit for road vehicles, including RVs and large motorhomes. Its 4 kW (13,650 BTU) output operates independently of engine heat, with stepless control that modulates heat output to maintain the required temperature.

The kit includes an EasyStart PRO 7 Day Timer and diagnostic reader, electrical harnesses and connections, a 6 m switch and power harness, stainless steel exhaust pipe with silencer, clamps and p clips, 1 m combustion intake pipe, 90 mm air outlet, fuel system with metering pump, fuel pipe and hose clips, 0.5 m of 90 mm flexible ducting, air entry grille, installation clips and screws, and an installation manual. The fuel system does not include a standpipe. Additional exhaust pipe lengths, air outlets and ducting are available separately.

Altitude adjustment is automatic up to 3,000 m above sea level, using the integrated altitude sensor. The EasyStart PRO provides text-based fault descriptions; heater and controller fault codes are stored in its workshop menu. Installation in passenger areas and near dangerous substances is certified. For integration with a vehicle fuel tank, an Eberspacher UK-approved fuel pick-up kit is required.

The potential service life is 5,000 hours, depending on installation and use; annual servicing is advised. The kit has a 24-month warranty.
