    Passat B7 Side Assist retrofit radar options

    Hi

    On a RoW model Passat B7, to retrofit Side Assist, one would normally use radars with part numbers 3AA907566 (left, master) and 3AA907568 (right, slave). I already managed to acquire a like-new right 3AA907568C radar for a very-very good price (30€+shipping) from eBay of all places but I still need to find a well-priced left radar. The 3AA radars usually go for 100-300€, depending on where its being sold and on the seller but I would rather not pay that much if I can manage to find a better deal. This better deal is a left radar coming from an Audi A6 4G or Q3 8U, which use the same radar HW and can be had for some 60-80€.



    I added a picture of the radars to illustrate the fact that these 3AA radars are based from the radars found on the Audi A6 4G, as the HW numbers begin with 4G0. My question is would there be a remote chance the originally 4G0 or 8U0 master radar will talk to the 3AA slave radar at all, provided the HW revision is the same? If they talk, then I could use "that other" program to flash both radars to 3AA907566D / 3AA907568D software level? If this seems far-fetched, then I'll simply have to pay up for a 3AA907566 radar.

    Also, if I get a 3AA left radar which has a different SW level (not C), would it talk to the right radar (C)?

    My particular radar is as pictured:


    An example of a Q3 radar:


    And an autoscan as per norm:

    Different software revision radars do talk to each other. I've flashed many Audi radars that are B vs. C radars. During flash both radars are flashed simultaneously .

    No experience with Audi/VW mixed installation....yet.
    I am a VW Freak - Le WV Freaks OR Come visit me at my work with ODIS concerns - FORSS ODIS GeKo/FaZit access for VW/AUDI/koda
    The world is my oyster...

    So I bought an Audi Q3 radar 8U0907566B, loosely fitted them to the car and the result - failure.

    When the Audi radar is connected, ACC goes offline, obviously because its on the same Extended CAN and doesn't like the radar with different software. Side assist module 3C does not appear in CAN gateway installation list. After disconnecting the Audi radar, the streering rack complains of the J769 going offline. So the 7N0 CAN does not speak to the Audi radar but the steering rack does. I think this is because the Q3 shares the same APA-BS rack that is on the B7.

    I guess someone had to try so others can learn from it. Now to find a proper 3AA left radar...

    Here's what ACC had to say about itself after I removed the Q3 radar:

    Not worth trying to flash the 3aa software to it once plugged in, even if it wasn’t on the gateway list? Or even getting someone with the correct module to read the eeprom, for you to write to yours and then try flashing the software again?

    There is the possibility that I mixed the CAN Extended pins up at the left radar connector. I was pressed for time and couldn't get the rear bumper completely off because of a torx screw with a stripped head, so I wasn't able to experiment any further at that time. I hope to try again during the next weekend.

    The file for flashing the radars to SW level 3AA907566/568D is available to be flashed with ODIS (or the "other" program). If after reversing the CAN the Audi radar starts to talk with the gateway, I would be good to go for flashing. If not, then I'll try to explore other options...

    As golfi_vend suspected, after swapping around the Extended CAN pins at the left radar, the Audi radar sprung to life.



    Though Lane Assist no longer works because the Side Assist radars not being calibrated?

    EDIT: Lane Assist works. It just needed its coding altered to reflect Side Assist being installed.

    Here's a scan of the Audi module...

    I should get the radars flashed tomorrow. I suspect the 02852, 01043 and 01024 faults would be gone then.

    Looking to add this to my S5 as well. What wiring had to be done to accomplish the retro fit. I only have the back up sensors, but have acquired the complete rear harness with backup sensors and radars. What additional wiring was required to get back to the CCM or was there any?

    I should add that I also added the blind sport mirrors as I wanted to get folding mirrors as well so opted to get both features at the same time.

    Ah yes, I still have the acquiring of the folding mirrors with blind spot indicators to be taken care of. This is the most expensive and tedious part of this retrofit.

    Well, on the Audi 8T platform there seems to be a single 16pin brown connector going into the interior from the rear bumper harness. It needs Extended CAN from the CAN gateway, switched power and ground. Also there are wires going to the door connectors, which carry the voltage and ground for the blind spot indicators and on/off switch in the driver's door window triangle.

    For exact wiring info, a temporary subscription to ErWin would help you out.
