Hi, the part numbers you have provided are specific to the EVO 55 heater when supplied and installed into a Mercedes truck during production. Can you confirm that your heater is installed into Mercedes truck still? Thank you

Its actually a crane, with a Mercedes engine.....transmission and vecu etc.

the ECU for Mercedes applications A0004469429 unfortunately is only available from Mercedes. Have you considered fitting a standard ECU? Okay, so youwould potentially also need to renew wiring harness and Controller, but then you would have a totally independent air heater in the crane
