Retrofitting Heated Steering Wheel

[Nuje]

There are additional grounding points on the MFSW. I think that once you have the wheel and put it in there, the length of the wires with those spade connectors should make it obvious what goes where.

It would not be a bad idea to find a photo of the interior of a MFSW setup and just make sure you have everything connected properly.

Hello Guys,
I would like to retrofit a Mk8 steering wheel (touch version with heating funcion) to my Mk7 pre-facelift. Is a new type 5Q1 clockspring necessary or an old 5Q0 clockspring with heating function is usable? Does the 5Q1 14 pin version have same pinout as the 5Q0 14 pin version? Thanks

You need a new clockpsring of the same "type" your car has now, either a new 5Q0 or a new 5Q1.

Someone earlier in this thread posted about how they had to move some wires around the harness to get the 5Q1 version to work. But it did work - and I *think* they were on a pre-FL car.

That was @mannymoda. I don't know if his car is facelift or not but he started out car was 5Q1xxxxxx from factory clock spring and updated to a 5Q1xxxxxxB. I think the issue was something funky in the adapter harness he had. And maybe at first glance he was making corrections based on the wiring changes required when going 5Q0 to 5Q0 with heat.

My original clock spring was also a 5Q1 953 569......I still needed an adapter to move to the heated steering wheel clock spring (5Q1 953 569 B)

There is still a problem though......this new arrangement works for a week or two before giving out. I have tried a new clock spring and had the exact same result.

I haven't had a chance to properly trouble shoot it. I have a couple of projects that need buttoning up but haven't had the time to attack them.

So, the clock spring works for a week or two, and then suddenly you have no heat again...? And you've had this happen twice now? Where are you buying the clock spring - dealer, or finding something from AliX or the like?

The reason I'm asking is that I did the heated SW retrofit on my wife's A3 e-tron (basically a Golf GTE), picking up a new gateway (OE one didn't support heated SW part) and a 5Q0953549D clock spring. Once I got the new gateway accepted by the car, I got heat to the steering wheel (this was back in early October...no real need for it yet at that point)...

but then when I went to clean up some coding in other modules (I was doing direct TPMS at the same time), I noticed it wasn't switching "on", or delivering any current. Nothing had changed with the wiring. So....my only thought is that the (AliX) clock spring went bad.

Explaining my plight to a friend who's a tech at VW here, he said that the clock springs have a really high failure rate. So, I just put in an order for a new one from FCPeuro - who have a lifetime free replacement warranty on everything.
Won't have it for a couple weeks. So I'll report back then on whether or not that gets heat back (and if it lasts).

I purchased both clock springs from a recycle'r in Germany......both came off low mileage cars apparently. Hopefully you won't be chewing through clock springs like me.

Something interesting, though unhelpful (haha)... is that when I went to do this retrofit I was advised to "upgrade" to the allegedly more reliable Kostal clockspring, which for me would be a 5Q0953549x unit. This would also mean replacing the stalks (and, as I found out, the harness between clock spring and lock cylinder). I even bought everything to go through with that swap then my dealer found a Valeo clockspring, 5Q0953569x that I could directly install.
There was/is a warranty extension on clock springs across several models/years but for our Mk7s I've mostly seen Valeo 549x units on NAR vehicles.

@Nuje has not had the best luck with the Kostal in his A3. And from what I can tell the 5Q1 in @mannymoda's car (and other later Mk7s) is a Valeo unit.
