Salutare baieti si multumesc pentru raspunsuri si ajutor, in special pentru Spido. Ne-am intalnit azi si schimband piese am descoperit vinovatul. Modulul de coloana 1K0 953 549 AQ.
Stiu stiu, este highline si ar trebui sa mearga dar nu merge si am descoperit si de ce. Stiind acum ce caut am gasit cateva detalii pe care ar fi trebuit sa le stiu inainte sa ma apuc de cumparat. Ce am gasit raspunde si la intrebarile voastre in legatura cu 1K0 953 549 BC. De ce la unii merge si la altii nu merge. Ei bine este la fel ca la AQ si AL si cine stie la cate alte modele. Trebuia sa fiu atent la varianta hardware a piesei. Se gaseste pe eticheta si se vede si la scanare exact langa software. Mai exact trebuia sa fiu atent si la HW nu numai la SW. Astfel, nicio varianta de hardware HW 638 SW 0070 nu suporta cruise control. Desi din punct de vedere software se codeaza la fel (0070), hardware nu merge. In speranta ca informatia ii va ajuta pe altii, mai jos o sa citez o parte din informatiile pe care le-am gasit (un citat este chiar de la un membru ross tech). O zi buna si atentie mare.
"Important thing to bear in mind is the HW or SW as a 0070 638 won't work with cruise regardless of what the part number is.
which I suspect is the problem with yours.
Yes, I've learned my lesson...
How do I find out the hardware and software on my AQ?
when you do an autoscan with vcds, you can see the 638 0070, it will also be on the sticker"
"You can code it, but it won't work.
this one no good

I have to agree with Niels here, there are certainly some part numbers where the software version is identical but the actual CCS support isn't exactly clear. That said, it isn't always 100% certain that those 3 digits before are actually the hardware version (as they are supposed to) or refelect the mounting scheme of the circuit boards.
Some examples from my archive/collection...
1K0 953 549 AQ @ 035 0070 = Factory CCS
1K0 953 549 AQ @ 036 0070 = Factory CCS
1K0 953 549 AQ @ 636 0070 = Factory CCS
1K0 953 549 AQ @ 638 0070 = NO CCS
1K0 953 549 BC @ 035 0070 = Factory CCS
1K0 953 549 BC @ 036 0070 = Factory CCS
1K0 953 549 BC @ 636 0070 = Factory CCS
1K0 953 549 BC @ 638 0070 = NO CCS
...similar lists could be made for AP and BD. Even though this hints that 638 is the problematic one, I would NOT bet on that scenario and still double check the individual cases!
That said, if one has a questionable module like this - always check if the pins are there and try to work with it. At this point I am pretty sure somebody messed up in production of these modules. They should have either received different part numbers (if they really didn't support CCS) or they should have supported it. I'm having a hard time believing this was intentional on the manufacturer side (whomever the supplier for these actually was... probably Kostal/KLO...) Another possibility is that they changed suppliers or whomever made them originally outsourced the unit. Plenty of possibilities, but in the end it doesn't matter - some part numbers aren't certain until you try them."
