MG Coolant Heater

[tom91]

This thread is to discuss anything around the MG Coolant Heaters, such as found in the MG ZS

I have started work on reverse engineering the Coolant heaters https://openinverter.org/wiki/MG_Coolant_Heater

Currently I can get it to draw HV power, however without a battery I am a bit stuck. Luckily Damien also obtained one so we can make progress.

Mine is installed in the L200 now and we have observed around 6kw so far. Simple one can message for control. Must get it into Zombie soon so can prove it out.

From what car is this nice tiny square coolant reservoir ?

Care to share 0x2A0 CAN command range?

Anyone has LV connector wiring schematic? I can only see CAN pins position on wiki. Does this mean heater doesnt use 12V power?
Never mind, i managed to actually read the wiki ...

Thank you...

We have something that works, the logs are online. We do not know exactly what all the fields do so it is still classed as experimental.

Good thing is the heater self limits its operational temperature to we believe 60-70C.

That is logical as i see about at 60deg the best all around utility and economy of power.

I intend to get one and fit it to our Ampera as our cabin heating stopped working for some reason. I replaced two heaters by now and still nothing. It seems heaters are not broken... so it looks like problem is in the system. I just about had it with Volt heater. But Outlander heater is too large. MG heater would fit nicely in small space i think.
I will get back to you with data when i had it in...
