Hi have a bmw wheel switch I am going to fit to the lower steering cowl.
T6 Heated Steering Wheel retrofit
- Thread starter carlg
- Start date
Generally speaking, if the MFSW has 2 wires for heating
it has thermostat built in the actual heating circuit(element).
You could very easily verify that by applying 12V supply and monitor the current consumption at the same time.
Probably bench PSU(with V & A display) would be the easiest.
By holding your hand on the wheel you should sense the heating and at the point of "max" temperature your current consumption should drop to zero.
And then when the temperature of the wheel drops to "min" the current consumption should resume.
The kind of down side of 2 wire heating is fixed temperature (oscillating with hysteresis characteristic of its thermostat).
The heating on 4 wire MFSW has 2 independent circuits. One for heating element only and the other one for thermistor.
In this setup the wheel temperature can be controlled and adjusted very precisely to any level as per the driver's preference.
But the limit is the clock spring tape!
So far I have found only spring clocks with 2 paths tapes for heating so my thermistor will be most likely redundant.
I could use PWM and by experimenting I should find 2 or 3 set poins (heating levels).
I didn't explore T6.1 setup but on T6 there seems to be no direct replacement of the spring clock unit.
My current plan is to extract heating tape from the donor and add it to my original unit (6R0 959 654).
Yes 2 tapes wound on top of each other.
So far it appears that 5Q0953569B is going to be the best donor of a heating tape and associated connectors.

How you getting on this ? I the same clock spring from a B8. I want to find someone to print a new 3d face plate.
My other idea is to use a hole saw to cut out the 2 pin socket on the donor then use the hole saw to cut a hole in the original then glue the two parts together
What do you think Robert?

I am thinking more less about the same thing. No progress yet though as I am trying to do probably too many things at the same time
I will try my best to precisely document my conversion and share with you all.
Not sure if you guys have seen this thread already, someone else has taken the ribbon cable from an MQB car and transplanted it into a PQ25 clock spring with some modifications...
I'm sure it won't be long now until we see the show off Robert 
It's something that I hope to eventually do with my van one day, I had a Ssangyong Rexton a few years ago with heated steering wheel (and, strangely, heated rear seats, I've never seen them in anything else since) and it spoilt me!

Chinese Passat on a PQ platform has heated rear seatsI'm sure it won't be long now until we see the show off Robert

I’ve got a 2012 Audi A3 with heated front and rear seats! I didn’t even know they were an option until after I bought the car second hand.I'm sure it won't be long now until we see the show off Robert

Having a play with my 6.1 and got this to appear, may just be that us 6.1ers have a way of controlling this built in ??
As is always typically the way I need to get packing and heading off tomorrow and no time to play/investigate but looks promising !

I don’t remember seeing that on mine. Maybe its an upgrade?

Hi is the clock spring different on a T6.1 from a T6?
I don’t want to derail this thread so think it might be better if I start a separate one for 6.1 heated wheel as the two are very different and don’t think either will help each other, when I make a bit more progress I will start a new thread and link it here for an easy find
Another small bit of progress.Look what I have discovered on my own MFSW.

How come I have missed that before
Maybe I got too excited with flat bottom and DSG paddle shift
Of the shelf, clock spring doesn't exist, but the investigation and the hunt already begun.

Disassembly of a "heated" clock spring.
Removal of heating tape(it is actually two tapes wound on top of each other).
First, tape detachment from the centre ring.
Second, tape desoldering from the PCB.
And the final result of the operation "heating tape removal".
More photos to follow soon
