Help for Cruise Control Retrofit Coding DIY ?

[BingoThePyro]

Alrighty,
Now, provided I coded that all correctly, there are no new errors (per say) but there is no new working items either.

I decided to run an ISTA scan and cleared all errors, then went for a drive round the block, re-ran ista to see if any errors appear/reappear.
I have these two that I may have missed earlier that may lead us somewhere.....
005087 EGS: Hardware, inputs, one-touch function
009520 DSC: Steering column switching centre, multifunction

Am I correct in think there -may- be something wrong with the replacement collar with cruise stalk?

Im starting to think theres something wrong with replacement switch unit. Do you have the part number? That thing is part of the DSC System, if its out of a 4 cylinder it would make sense it doesnt work.

I'm going to have to pull it off to get the number.
Going to be out of town till next week so will swap old collar back and make sure everything still works and go from there.

ok, with $544 instead of $540, cruise still worked, but did not display speed in the dash (kombi)

Have put original collar back on, removed $544, fa_write CAS an NFRM, done sg_codeirin on all ECU's, re-cal steering and sensor (via ista+ this time) and the results:
-Steering wheel buttons all work again
-NO reverse camera - there were errors coding the TRSVC. Also shown as missing box in ista+.

COAPI-2020: SG antwortet nicht IFH-0009: SG nicht angeschlossen oder meldet sich nicht TRSVC70
COAPI-2020: SG antwortet nicht CODIERINDEX_LESEN

It somewhat appears that <maybe> doing a 'code car' broke my TRSVC unit - though I would like some more expert advice on this.

I have uploaded photos of numbers on collars to original link.
Also came across this site: http://www.realoem.com/bmw/enUS/show...diagId=61_3088
This appears to have the coding options for the different configurations.
The original collar number appears to be 123 033 and the cruise collar is 123 041.

Summary:
No reverse camera (TRSVC broken somehow?). PDC works fine.
Cruise collar has working cruise, but not steering wheel buttons (but horn does)

PLEASE HELP!!!
I have installed hardware for cruise control retrofit on my 2012 E82 135i (tuned) I added the go code to the frm and the instrument cluster. But can’t access the dsc it just won’t read it. It says chassis E87 at the top when I press it, is that possibly what car the part was from? Is that the issue ? If so how do I fix it! I have dsc warning lights on dash now. I also was in auto pilot following a tutorial and coded it to the ECM. Does this mean I also deleted my tune? really need help on this
