The one with the bigger hub diameter almost certainly, but you know what, phone them and ask.

Item 12, four M10s by the looks of this: LLLParts

I suggest repair the cables shown in figure 3 before doing anything else. I think fig 1 looks normal/OK. Freedom membership enables indefinite editing, and many other enhancements. Membership Options (Freedom) - BRISKODA

Adds risk (of shearing one off for example) to change ones that aren't faulty, I wouldn't.

What year car is the replacement cluster from?

Major differences, pre-facelift are CAN, for starters. As per PM, I haven't found a match for what you need, unfortunately. If I think hard about it I may be able to build one out of bits and pieces of others; that has the right chirality and function. The thinking hard bit of that intimidates me a bit though.

Sadly that's a pre-facelift motor module you've acquired, and won't play nicely in your car. You need 6Y2959801. I may have one...

Pass side wiring, annotated Driver's side, not as annotated: The only connection between the two is the LIN data wire which goes from pin 3 of each 8 way to the other, and nowhere else.

Does driver's side window work OK? Part number of unit in pass door? Will add some wiring diags next time I get up and go to the big Internet.

Only the vRS has the bigger M10 ones I think.

What makes you think M10 x 52? I'd expect M8 x 48 Part number N91108201 (12.9 grade High Tensile)

Spot on. There will be minor differences between these NBW, LHY etc boxes but all are 0AJ family boxes. If you PM me your VIN I may be able to find some part numbers of the specific bits you're after.

6Y0/6Y1 was discussion about the warning light. 8T0/8Tn (where n is a non-zero numeral) was a broadening of the discussion to include whether the OP's car had CC factory fitted, or retrofitted. I think it's very likely that some countries require such a warning light to make the driver explicitly aware that non-human control is active.

Leave it until it fails MOT. If you replace it now with a cheap pattern part, that may well fail sooner than your existing one would have if you'd left it on.

I don't see a code for with/without cruise control in your photo. You may need to get the full car data to look for a code like 8T0 (without cruise control system} or 8T1 etc. Only if you are interested to know if the car was built with CC, or it was retro-fitted later. I became interested in this after retro-fitting my 9N Polo, then my partner's Mk1 Fabia with CC last year, both had PR codes 6Y0 and 8T0, naturally. When I investigated (on the Polo) I found no LED in the relevant position of the cluster circuit board (but the symbol cutout was visible in the panel), but also there were other components associated with the LED missing. I decided that even if I could correctly identify all the missing parts and fit them, the cluster software might not have the relevant code to illuminate the LED appropriately anyway, so I stopped pursuing it. The only time I find it non-obvious that cruise is active, is when it is set, then you speed up for a while ('manually' with accelerator pedal) and maintain a higher speed, then come off the accelerator but don't brake (say when approaching a roundabout). As the speed dips below the cruise setpoint, it takes over again. I wasn't aware that cruise control might do this, never having previously driven a car with CC.

PR code 6Y0 means without cruise control warning system, 6Y1 means with. You may not have either on the sticker though, as that only contains a small proportion of the build codes. May need to get full 'car data'. This seller offers a reasonably priced, rapid service on this info. VIN decoder that will show factory options Audi VW Seat Skoda | eBay

Post a photo of the build sticker from the boot floor (or decode all the PR codes yourself). It may show whether or not the car had CC from the factory. If it did, there's more chance an LED is fitted, if it didn't - less chance.

Wheel bearing?

You'll have to wait for owners of 2006 mk2 Octy to say if their car such an indication. Maybe CC was retrofitted?

All Fabias have CAN bus, but it won't be relevant for a stand-alone aftermarket system like Keith's, I think. Thanks Keith, by the way; my partner is delighted to be getting this late Valentine's gift. Super-romantic, right? 😁

Quite likely not something that this model is built with then. Other owners can confirm or not.

Did this green light work before now, and now doesn't? It will be a surface-mount LED soldered to a circuit board, not a bulb, if it exists.

A handy site to see which part numbers actually are equivalent is skoda-parts.com Type in a known correct part number for what you want, and it tends to take you to the page selling the latest version, but very helpfully all equivalent part numbers get listed in a grey font just under the main item title. e.g. https://www.skoda-parts.com/spare-part/6r0615301c-front-disc-brake-256x22mm-ferodo-4177.html

Not something I can help with, sorry. Others are more than welcome to chime in though, if they have useful knowledge of such things. There are lots of things in ETKA that remain mysterious to me, I'll probably add some later as I think of them, in the hope someone can demystify. 🙂
