1 x Side Assist Lane Change Wire Cable Harness For VW Golf 7 MK7

All cabling confirmed good.

Internal LEDs put in temporarily as I'm waiting on door pins to wire in the mirror glass.

Am I right in adding Module 3C (Lane Assist) to get access to the side assist radars? I'm getting a timeout.

I have confirmed wiring is all correct and present, all is good.

(I had made an Eprom change on the instrument cluster to enable side assist menu in 3D Cluster when it was out and I was swapping from B&W to Colour)

This is a retrofit, I do not have the lane assist camera module. I'm praying hoping that side assist can work without the lane assist camera.

I check my wiring from the plugs all the way down to the radars but I'm still not getting any connection to the controller.

Funny, the LEDs that I'm using stay turn on, one at full brightness, the other at a lower brightness.

I'm wondering if the full system, including LEDs need to be connected for the controller to communicate.

Which way you have connected the modules? You know master is on the passenger side on LHD cars and slave is on driver side?

And does not need lane assist camera, works without.

Thanks, Downtime.

Yes, confirmed I swapped the units around with no avail, The cabling flows though the right hand side into the master and slave is on the driver side.

Am I missing something by not connecting the LED's on the wing mirrors, are they required to complete the circuit maybe?

Yes, they are required. Otherwise it will fail out. BUT it does not affect the communication to the units. Have you enabled extended CAN on your can gateway? Can't remember exactly as it has been quite a while since I've coded PQ platform car but it was either in coding or adaptations. 3C is connected to extended can and if it's not enabled from gateway they're not communicating.

Also double check the connections. MQB wiring is not exactly the same as PQ on some occasions.

5Q0 907 686 C (right, J1086) has CAN HIGH at pin 3. Respectively CAN LOW is pin 4 (as wire colour orange/brown suggests).

Quick sanity check here, this is the layout.

Am I mixing up my right and lefts here.... (when I swapped them over, nothing lit up or came alive.)

Thanks again all for your help so far! It's so simple, its complicated... I know its about 8 cables, I just don't get why comms are failing.

I tapped into the TPMS extension going into my Extended Can Gateway pins 7/17 that I connected the TPMS into, then out of that the radars connect.

Is piggybacking allowed? perhaps that's the issue?

686 is master and in Right side, you already wrote that on beginning.

When you added 3c to your gateway 19 instalation list did you re write /save coding? As its not showing on your scan ?

I did this exactly same retrofit to my 5N Tiq sometime ago and those modules should be online, even without mirror indicators.
I used Golf7 wiring kit from Ali and changed pq door pins to it to match my Tiq and installed Sharan mirror classes.

This was one of my info source Drive2.ru link for coding and other infos. I am using Tiquan dataset and with it radars have worked quite nice.

Thanks so much @juppep did you take any notes as you went along on your Tig?

I can't get registered on drive2 to ask questions to that user, as they're not setup for Canadian cell#'s for verification.

As we're using the exact same setup - can you let me know where you connected your CAN HI/LOW into? I'll need another week before I strip the bumper back again to do one final analysis. As honestly, everything is connected correctly on paper but no comms. I'm racking my brain thinking it has to do with the connection into the extended gateway using the CAN adapter that came with it.

Again, thanks EVERYONE so far, I'll divert my attention to the CAN and Power to see if I can bring them online and what's going on late next week.

Those are connected to pins 7 (Can-L) and 17 (Can-H) on CAN-GW (Extended Bus). CAN-GW pin 7 <-> 4 and 17 <-> 3 on module.
I remember that there is separate adaptation channel on CAN-GW to enable/disable extended bus and that would be one possible thing to check.

Surely if direct tpms is working there is no issue with the above?

Is direct TPMS on PQ platform part of extended can or drivetrain can?

Are you 100% sure your vehicle has Extended CAN? Mid-low line vehicles without factory ACC, SWA/RCTA, or advanced forward lighting can be equipped with CAN gateways that don't support Extended CAN. Check factory wiring diagrams to see where your Headlight Range (J745) is hooked up, I don't recall how that works on PQ.

If your J745 is verified on Extended CAN, you should be good, and you should be able to use a multimeter to check continuity between the CAN hi/lo pins at your new SWA/RCTA against the gateway and/or the AFS module's pins. If your J745 is on something other than Extended CAN, you may be missing some wiring and gateway support.

Headlight range control module on PQ platform is on drivetrain can, not extended.

i think OPs gateway has extended can. It is 7N0 gateway.

A few things:
  • VW, as in all things, seem pretty good at removing extra wires or devices/options in cars that can do without them
  • If Headlight Range isn't on Extended CAN, then this car has no Extended CAN devices that I'm aware of
  • If the gateway has no clients on a given bus, and therefore gets no ACKs to the CAN bus traffic it forwards out, it should log a Defective DTC
I'd like to see a complete Auto-Scan with 3C turned on in the GVL, in case the gateway is doing something smart to disable Extended CAN when it has no registered participants on that bus. That needs to be done anyway.

Aside from that, I'm not seeing anything here that confirms support, and I'm seeing several things that indicate possible non-support. That said, I don't have a database of gateway part numbers I'm working from, just operational experience with folks trying to get openpilot working on mid/low-line cars without ACC.

I know because I retrofitted the same can gateway to our ex Golf Plus.
You’re right that it needs to enabled separately so it can register devices connected to it.

And afaik on that age Tiguan have no modules on extended can
