FAQs
Is this a complete heater?
No. This is a replacement electronic control unit for a compatible Espar / Eberspacher Airtronic D5 12V heater. It is not a complete heater unit.
Which heater does this ECU fit?
This ECU is listed for the Espar / Eberspacher Airtronic D5 12V heater with heater number 252361050000. Always confirm your heater label and part number before ordering.
Is this ECU for 12V or 24V heaters?
This listing is for a 12V electronic control unit. It should not be used on a 24V heater unless compatibility is confirmed by the correct Eberspacher / Espar part number.
When should I replace the heater ECU?
ECU replacement may be required when diagnostics confirm a control unit fault. Starting issues, shutdowns, or fault codes can also be caused by wiring, voltage, fuel supply, sensors, glow pin issues, or installation problems, so the heater should be diagnosed before replacing the ECU.
Can this ECU be used to repair an older Airtronic D5 heater?
Yes, when the heater is the compatible Airtronic D5 12V model and the part number matches. Check the heater model number and existing ECU reference before purchase.
