Hi Jeff

Thanks for the info, removed front bumper to replace a parking sensor and had a look at the auxiliary heater at the same time, found the three electrical connectors unplugged. Once connected auxiliary heater been working as it should.

Thanks

Brian

My XJ X358 Auxiliary Heater is not working, scanned with iCarsoft V2 code reader and is showing error code B2537.
No start auxiliary heater

Can’t find any information on this code.

Any help would be appreciated
