Auxiliary Heater Not Working

[brianpeat]

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

Did you get it sorted. If not have a look on the S Type forum, I've posted on there how to fix it using the icarsoft scanner.
PS I know this is an old thread but the post might help someone

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

Great result Brian I've read in the past that some owners disconnected the said heater because of the smoke on initial start up eg fumes geting into the cabin. But for me that was a small price to pay for a lovely warm car after a mile or so.
