Passat Clock Spring

[iampivot]

Thx, do you happen to know the torque spec for it when it goes back in again as well?

[Umai Naa!!]

No.

I just use my best judgement. Usually as tight as I can get it, with a 1/2in dr ratchet.

By the book, you're meant to replace the micro-encapsualted bolt, too.

[iampivot]

Do they sell those at the VW dealer parts shop?

The micro-encapsulated bolt i mean. I assume it's because it has some loctite on it?

[Umai Naa!!]

Yes, can be sourced from VW without issue. Whether the dealer has one on the shelf is another thing. Worst case, they can get one in 1-2 days.

There's a guy in this video YouTube that says it can be used five times. But how would you know if the garage has already undone it a few times during service? I guess the garage changes them every time.

Normally score the bolt each time then you know when to change it.
Torque is supposed to be 50nm from memory...

Got a new clock spring installed, but the angle sensor seems not to be initialised; getting the 'this seems to be an uninitialised control module; valid WSC/Importer/Equipment data may be required' message in VCDS. I tried using both the current values in the module and using the suggested defaults from VCDS, but it's not working. I seem to be unable to set the WSC code to the values that were on the previous sensor: the input field is greyed out. Is there a trick to doing this programming?

[Umai Naa!!]

Have you driven it yet?

[iampivot]

Yes. Should it usually fix itself?

[iampivot]

It's weird, I can't get the angle sensor working. I can see the angle measurements if I go into 44 Steering Assist and select measurement, but not in 03 ABS brakes. Log file is here; Thursday,07,June,2018,18:03:46:47231 VCDS -- Windows Based VAG/VAS Emulator Run - Pastebin.com

The new angle sensor seems to be made in 2016 and has an updated hw / sw version relative to my old one from 20123, maybe I need some other modules updated or a different angle sensor?

Are you following the procedure as documented on the Ross-Tech wiki:

[iampivot]

Yes I've tried that, but am getting the "group 060 not available" message. I read somewhere that it might be due to other issues not being resolved though so will try again.

I got it going this time, so everything is working again now. I ordered this part; Fit For CC Passat B7 CC 3C Cruise control electronic module 5K0953569T 5K0 953 569 T-in Steering Wheels & Steering Wheel Hubs from Automobiles & Motorcycles on Aliexpress.com | Alibaba Group The price varies a bit with a sale on every now and then. The part is made in china.

Hey all, I thought it better to add to this thread than start a new one. The airbag fault light came on for me last weekend.

I was planning to soon replace the current wheel with one that has DSG paddles, and it seems that even for a mechanical illiterate such as myself that doing the clock spring is not a lot more work once you've got the wheel off. So I don't mind getting the part and doing this myself, the only thing is that I just want to be as sure as possible that it is the cause of the fault.

I've read (perhaps here, perhaps on passatuk forum) that when it's the clock spring often you lose the functionality and illumination of the multi-function steering wheel buttons, and even lose the horn? My MFSW buttons aren't connected at present (a legacy of replacing the head unit - will add a new harness for this when I get around to putting in a reversing camera), however they do illuminate and the horn still works.

Apparently there's some wiring under the (passenger?) seat that if disturbed or a connection is broken that can also set off the airbag fault? Is there a way outside of a workshop of checking what is definitively causing the fault?

Any advice would be super appreciated!

[iampivot]

If your horn still works, then it might be something else than the clockspring. Try to get a readout of the error codes, it will indicate if it's the clockspring or not.
