Thread: D3 ECU Manufacturer

It should be Siemens at least for the TDV6.

Thanks in advance

If you're talking about the Body Control Module / Central Junction Box it's made by LEAR Global Automotive Tech Leader | Lear Corporation

Not sure why you're asking though, they will not provide you with any support or information, as far as they're concerned it's a Land Rover product.

Thanks for that.

I'm looking to see if we can save the settings and use them on a new or a second hand unit. There are people around now who fix/ re-code units. I think mine is playing up.

Well the cloning process for the D3 BCM is well known & documented.
Basically if you have an xhorse VVDI then you can clone one BCM into another.
It's been the solution for a while because to get a brand new BCM it has to come from the UK with new keys as well.
Whoever wrote the software for the D3 BCM was a genius, it won't allow any access for programming unless a valid key is present and the ignition turned on.
