D4 Remote Heater Mod Parts
Looking at adding a webasto telestart box in the boot to enable remote starting.
The genuine LR part is a T91R.
Does anyone know if a VW Audi T91R module will work? Ebay is rife with thes for little money.

Pretty sure they won't work.
I've got plenty of stock of the LR ones. Bodsys Brake Bible
But thinking about this, Altox wbus will work on Vdubs as well as LR's (ask me how I know ) so can the protocols really be different?
I've wired many an Altox into the D4 rear plug and have adaptor plugs, so it may only be plug / pin layout that need sortingAltox GSM FBH controller thread

The telestart boxes, connectors and remotes look identical.
Not sure on the difference between the T91R and the T91.
The telestart seems to only provide a LIN (w-bus) output to the heater, and nothing on the CAN bus. So I wonder if the heater sends a can bus signal the hvac ecu telling the cabin fan to run?
Might try one of my own D3 heater interfaces on the w-bus line later.

The rear plug in the D4 is inly 3 wires, ground live and pin 2 of the FBH, therefore the FBH controls the HVAC Altox GSM FBH controller thread

Weird. I'm sure I saw a VW with the same connector as the LR one.
Have you got the remote too?
Did you do any testing with it on a D4 or not as the plugs are different?
Perhaps I could identify the correct pins and adapt it to test on my D4.
