since there is little or no info or wrong info for coding acc here is guide, maybe it will help someone, it's always better to have it in one place i helped a friend retrofit acc well almost...
he bought used radar, cheaper and also no need to calibrate/basic settings, 3AA907567 with bracket and connector, extended cables and connected
waiting on ABS to finish retrofit, ABS supporting ACC:
3AA 614 109 E, D, Q, T, AA, AE, AJ, AN, AM, AR, AS, BB, BC, BJ, BL, BN, BS
after replacing abs code it, adjust adaptation channel 021 overboost level, then 061 Hydraulic brake pressure and basic setting well documented on vcds wiki
ps. if you need to activate or de activate PLA: security code70605 - adaptation channel 97 set to 1 or 0
acc radar pinouot:
pin1 - not used
pin2 - ground
pin3 - not used
pin4 - can bus Ext. High (gateway pin17)
pin5 - can bus Ext. Low (gateway pin17)
pin6 - not used
pin7 - not used
pin8 - to steering wheel module to pin5 keep current wire (if you have cruise control you have this wire, otherwise you will have to add it, it connects to ECU)
pin9 - ground
pin10 - fuse SC4
coding
1. can gateway mark 13 - Auto Dist. Reg. in installation list
2. code engine control unit, in b7 passat these bytes were unrecorded so had to search in order to find values, use L2Code mark byte 4 bit 5 ACC
3. code steering wheel activate assistant menu byte 0 bit 1 and acc byte 2 bit7 (also unrecorded 00-no cruise control, 20- cruise control and missing 40-acc)
4.code abs, to current value add +114688 if supported it will be accepted otherwise no, been there, done that
5. radar can be coded 10000 manual transmition or 10100 automatic (DSG) transmition but in order to recode it there is a procedure, of course we had it coded for manual instead for dsg
we need to unlock coding:
enter security code 21056
adaptation channel 2 set to 201
change coding either 10000 or 10100 after that we need to relock coding
adaptation channel 2 set to 1, recoding is safe, basic setting are not lost
cycled ignition two times and you're golden or waiting for abs
i'll post a scan after we get abs
