Oof. Does this mean you will have to go ahead and do it yourself?

It sure does. Iíve started sourcing parts but beyond the pedal assembly Iím stuck between three options:
1. 6 spd
2. Zf 5 spd
3. Full retard CAE

If youíd like to help out to see the process then shoot me a pm and we can coordinate

Alright, fixed PDC: it turns out I didn't plug the speaker back in. I didn't realize that the PDC warning speaker was on the driver's footwell panel. Feeling pretty stupid about that. Also double checked our wiring, looks good, but it's possible I'm misunderstanding something.

So now everything works perfectly except for cruise control. INPA scanned almost all possibly relevant modules to the wiring/swap (DME, cluster, EWS, DSC, PDC, ALSZ) and zero errors in all of them.

Tried to access the cruise control module in INPA ("Cruise Control GR2" under "Body") and it gave me an error saying it couldn't access it. Also said something like "Rover must have cruise control activated to access module". Tried it again with engine on and cruise control turned on (pressing the I/O button on the wheel does light up the CC dash light indicating CC is on, although when driving it won't let me set a cruising speed with +), same error.

Should the cruise control module be accessible via INPA in our cars? If so, given that literally everything else works with no issue, is it still likely that my wiring is the culprit? Or maybe there's something we forgot to plug back in while we were reassembling the car that *only* affects CC somehow? Thanks for any suggestions!!

That sounds like the cruise control option wasnít coded back in but I am by no means an informed source with electrical/coding.

E46 M3s don’t have a cruise control module. It’s all built into the DME.

Most likely you either have the wrong clutch switch or it isn’t wired properly.

Ah, good. Thanks for that clarification. I did notice in NCSExpert, however, that my VO/FA doesn't appear to have the code for cruise control option in it (which I think is $540?). Or do M3 VOs not have CC code in them because they have CC by default (at least they all did until 2005 with the ZCPs). Can anyone confirm what the CC VO code for CC is, or that it doesn't have one?

DME error code 80 (Schalterkette Kraftschluss -- "Switch chain friction") re-appears periodically (every couple hundred miles or so), which, according to some lore I've found out there is related to the clutch switch, although, there doesn't seem to be a good consensus out there that I've found on what this code actually means or what causes it. Some people say clutch slippage, some people say clutch switch, etc. Most discussions of it I've found by googling have been in the context of E39s. Saw early on in this thread that Kaiv encountered it years ago after a swap and didn't seem to know what it meant at the time, but there was never a follow up post.

But yeah it seems like the problem is either with the wiring or with the clutch switch itself, or its connection to the MC. For the clutch switch I ordered the P/N in the DIY OP I'm and pretty sure I checked the P/N of every item I physically received against the list, so, likely just poorly wired?

Haven't had time to chase this down lately, but will report back when if/when I figure it out.

I think there is a VO option for CC, but it won't impact anything one way or another.

That error code could be anything to do with the clutch switch or gear recognition sensor.
