Having a remote control fuel burning heater allows you to warm your car from the comfort of your house – a definite bonus for cold British winters, no more scraping ice and freezing fingers on cold mornings!
The remote heater (Webasto Telestart) was an expensive option that few L322 Range Rovers were fitted with, if you have a TDV8 model however you probably actually have the wiring already in place, and may even have the receiver module. It is possible to buy a fob and program it to your receiver but the remotes are expensive and the programming doesn’t always work. Here’s how to convert your heater to be controlled from your phone, including setting timers and regular heating schedules.
I used a cheap 12v WiFi enabled switch – see the bottom of this article for an Amazon link to get one.
First thing you need to do is find the wiring. The receiver module is fitted near the fuse box behind the right hand side panel in the boot. Remove the panel and you should see something like in the photo below. The wiring for the receiver module has been unplugged (it’s the loose cable hanging out). The receiver itself it mounted to the back of the metal panel, shown by the red arrow. You can just reach over and pull the plug out of the top of the module.
Cut the plug off the wiring (keep it safe in case you want to reinstate the standard controller in the future). I used cheap pre-insulated bullet connectors for this install. You can splice new wiring in, use professional connectors or just chocolate blocks – whatever you are comfortable with!
There are only three wires, +12V (Black/Red), GND (Brown/Black) and a switched live (Yellow/Green). Apply 12V to the switched lived and the heater will run.
Prepare the Wifi switch for fitting:-
We need to feed 12V to the Input+ and one side of the output and Ground to the Input-. The other side of the output will connect to the switched live that originally came from the receiver in the car.
Taped up to make it a bit neater:-
And connected to the wiring that we prepared earlier:-
You can mount it however you like, I just used double sided mounting tape for ease:-
Now you need to download ‘eWeLink’ from the app store to your phone (Android and Apple versions are available – it’s free) and follow the instructions to configure the switch to connect to your WiFi – all done, easy as that!
From the app you can now switch the heater on & off:-
It is worth setting a timer to turn the heater off automatically after a set period, so you don’t flatten the battery if you forget about it! (the original Webasto receiver runs the heater for 30mins then switches it off again)
You can also set up a schedule, if you want to automatically heat the car up at set times (for example every weekday morning before you leave for work)
Note – I did this on my 2007 L322, I can’t guarantee other years/models work exactly the same way, so it’s best to check your wiring etc. before you commit, any messing around with your car’s wiring is done at your own risk!
Here’s an Amazon link to the type of switch I used – I have no connection to the seller. You pay the same price as you would normally but I get a few pence back from Amazon if you use this link to help towards the website fees.
UPDATE! – the exact switch I used no longer appears to be available online, so I’ve updated the links below with some alternative units that should work just as well (please note I’ve not tried them personally). If you have any success or problems with these WiFi switches please let us know in the comments below!
