Heated steering wheel retrofit

I bought myself a flat bottom steering wheel for my car and was fortunate enough to find it was heated as well.

As my car didn’t originally have a heated steering wheel I just went ahead and fitted the wheel to see what would happen. As I guessed the heated wheel button would not illuminate and no heat could be felt around the rim.

I did a few searches through this forum and saw a few posts where others had asked about fitting a heated wheel but no one had came up with a final solution as far as I could see.

So after speaking to a jaguar mechanic I know I managed to find out that our cars are pre wired already for a heated wheel and that a module needs to be clipped into place behind the steering wheel which has two contacts that run around two brass rings at the rear of the heated wheels.

Part number is C2C7505.

Fitted the module, clipped in the grey plug which is already in the car under the lower cowl and happy to report I now have an illuminated button and a toasty steering wheel just in time for winter with no coding required to the car at all.
 
Well done that man 👍🏻

I have a flat bottom wheel with illuminated heated switch but it’s not heated :roll: :lol:
 
That’s really great to know.

Next question, I don’t suppose you took any photos you could share please?
 
I’m afraid not but if you are comfortable removing the airbag and steering wheel plus the lower cowling it’s pretty self explanatory. Just don’t forget to disconnect the battery before unplugging the airbag terminals.

I’m curious to find out how that works? :lol:

But he's said it doesn't work!
I guess the wheel has no heating element ... ;)
 
I’ve been extremely lucky & managed to find a module for sale on eBay for £75 so I’ve snapped that up along with a new heated steering wheel. Bluebro, I don’t suppose you live in the South of England by any chance do you?

It’s the button lighting up when it’s not a heated wheel I’m interested in :D
 
The buttons were the old flat type - the volume one was getting a bit sticky and the right hand side cluster was just a blank too.
So (with great assistance from dbv6s) I swapped them for the newer profiled buttons, so have a full button complement on both sides now.
You keep the original electronic boards and just swap them into the new buttons.
So I guess the heated steering wheel LED was illuminating before - just behind a blank button for some bizarre reason!

Was there a circuit board behind the full blank on the right hand side?

The change Lunar and I did was just changing the plastic switches over - circuit boards remained the same as original ones which came with the car. Easy swap, 30 mins all in if you know what you are doing
By keeping original cars circuit boards you are guaranteed not to have any electrical issues (Some have reported changing switch packs and buttons not working). The only think changing is plastic
 
Sorry Bluebro - I missed your reply there - thanks David.

And yes there was a board behind the RHS blank.
 
Electrics baffle me sometimes especially in cars.

I also fitted memory seat switches as I hated the plain looking seat switches for my 6 way seats, low and behold I now have the memory function, no lumbar but memory works a treat and the switches look a lot better.
 
Nice win!

It does make you smile that you have to bend over backwards to achieve some retro-fits and yet you can come across things like that.

As for the seats, I'm the only one who gets to drive my car so I don't miss a memory function and prefer the lack of extra motors and weight.

I quite like the bit of gloss black trim and the cool of the aluminium door handle - not so keen on the later matt black handle option.

All personal choice though and horses for courses.
 
I’m the only one driving my car too thankfully, although I have to say a pet hate of mine is getting the car back from Jaguar only to find the tech has moved the seat and struggle to get it back to that ideal position you had it in for so long. :x
 
Finally got around to doing this mod myself.
Retrofitted an SVR wheel sometime back, but didn't have time to t research the heated element, although it had the buttons and loom, so I used my old loom and buttons at the time.

Wind forward and Blubro's post and free time with Xmas and a lockdown made me think about getting on with it. Sourced the module from Ebay (actually turned out to be Bluebro as the seller..) and was a pretty easy job of airbag off, drop the bottom cowl, install the module and refit. Of course it didn't work, nor did much on the steering wheel to be honest - radio, cruise, paddles, phone, etc..

Through a bit of trial and error and airbag on and off a few times I got the break through using the right combination of SVR wheel loom, which had heating cable in it and extra connectors, SVR RHS circuit board (even though my original had the switch on the board) and my old 'S' LHS circuit board. Without the mix and match I could not make it work. Reassembled everything with SVR buttons for consistent shape and feel and all good.
Wheel gets properly hot and all the aux functions on the buttons work as usual.

As a footnote to anyone else doing it there is no need to connect anything else other than module on the column as the wiring into the dummy module is clearly already live and no coding needed either.

Now to to wait until I have an important reason to drive the car :)
 
Morning Guys

I’m finally ready to fit this mod. Could anybody explain how the bottom cowl comes off or maybe even have a picture of the plug I’m looking for in situ please?

Cheers.

Removing the cowl is a 2 minute job. Just a couple of torx in deep holes on the underside and it pulls down and out.
I suggest move the steering wheel up and out. That gives most room to remove the cowl.
Go through airbag removal process then the cowl.
You’ll find a blank module on the lower left of the column by tour knee. You’ll see the cables in it. Press the release tab an swap the dummy module for your new one
That parts then done and you can put cowl back on
You should see the 2 spring loaded contacts point to where the back of the wheel has its respective contact rings
Good luck
