Jef, Dana, and Jack thanks for going above and beyond the call of duty to help out with this little blue devil!
Spent some time with car today looking at data and more inspection just to be completely certain no faults exist in car. As expected nothing out of place. Car was hit in RF corner and all the repairs look solid. Really no wiring to speak of in RF. Removed in LF wheel housing to inspect and it was clean. Just to be sure scoped data lines and SCCM and . As expected no faults in signals and patterns matched. Data line pins at and SCCM in correct slots and tight. I see no faults with this car like before. I put PMI scan next to latest scan with AL part and all modules part numbers, HW/SW VERSION numbers and coding matched. Only difference being J527 P/N.
Crash picture, however car is repaired/re-assembled
Shop had picked up another AL to program lol. Knowing its was probably a waste of time I gave it a whirl anyway. Surprise surprise fault 18275 set in trans. Hunted all over car to make sure no aftermarket electronics and none fitted to car. Had shop drive car a ways but fault still wouldn't unlatch to clear. I really have no idea what "missing message" from J527 trans is expecting to see. I should also mention all the column switches function, wipers, signals, lights etc... The thought crossed our mind if we could find a for trans possibly we could flash the garbage out of it. No such luck not appears this trans has no updates.
Jef "Or due to how super rare it is, this was a factory "hack job" to get a very limited run of vehicles out the door since 99.9% of Tiguans are not stripped down like this.... and now the parts departments has no info on said hack"
Jef I think this is hilarious but very possibly true. This car was a total cast off anomaly given lack of options, strange part numbers and crazy supers. Otherwise ya could be an issue with but I'm just not willing to go there without a solid baseline J527. Still possible code was pre-existing to repairs and clockspring replacement. Would simply be a massive coincidence. I looked at shops pre scan and it was completely botched. Only 5 modules reported and no codes. Seems they didn't configure scan tool right or something. So the door is shut on the pre-existing debate.

"5K0 953 501 CL steering column multi-switch
Part number is replaced by several parts (multiple supersession)
5K0 953 502 L 9B9 steering column multi-switch 1 satin black
5K0 953 569 AJ electronic modul for steering 1 col. combination switch
5K0 905 865 ignition starter switch
5K0 953 223 mounting plate for 1 steering col. comb. switch
1K0 905 851 B steering lock
That's one hell of a list of extra parts.
Moving forward, 5K0 953 569 AJ then supers to 5K0 953 569 AL but it almost looks as if you need to verify all of those other parts are also matching part numbers? If so that doesn't directly explain the initial concern because I don't see how the part number of the ignition switch and mechanical steering lock is gonna help with a Powertrain Data Bus .
Dana I think you observation with all the steering column part supersession is brilliant. If I'm understanding you right your saying what if the AL J527 needs the updated switches to be compatible to the car."
Dana thats a brilliant observation!
Makes me wonder if the AL would need the updated column parts to truly be compatible. Would like to think the parts catalog would lay that out but as we know they can get things twisted up here and there. I'm sort of glad I'm won't be making the call from this point forward considering who knows many pricey modules the dealer might wing at this thing.

Great find with the
ebay part! The listing says "Doesn't post to US". Not sure how I could get around that. Also I noticed the pic of part seems to be missing the clockspring ya?
I'll post a final scan up once the car gets back from dealer. Appreciate the time guys!
