Lane Assist camera retrofit - Need help from those with ACC and camera

[vw-ac]

Hi,


So I have a 2013 mk7 Golf that has ACC factory fitted and many other extras. One of the few things missing was the front assist camera (A5 module). I recently had my windscreen replaced for one with the camera bracket. After much research and speaking with someone specialising in retrofits I decided to get the windscreen that supports the later mk7.5 facelift camera (3q0). I fitted the camera, added the wiring harness, including the canbus wires to my factory fitted ACC radar. I had someone remotely assist with the calibration and checking over the coding and adaptation changes. This is where the issues started - with the lane assist camera coded I had an error that lane assist and ACC were unavailable. The guy then tried to get ACC back by changing the coding of my A5 camera to tell it I don't have ACC fitted. This results in ACC working again. I have no errors until I try to enable lane assist - it then flashes up that lane assist is currently unavailable.

Traffic sign recognition is working fine (on my nav unit it displays, but not on my instrument cluster - if I try then I get a software version error on my instrument cluster - I believe the unit has too old a firmware version to be able to handle the sign display). High beam assist works perfectly though.

With the camera coded to not have an ACC radar, then I have a single databus error on the A5 module. If the camera is coded to have the ACC radar then I get multiple databus communication errors.
The guy that assisted me with this says that it must be my gateway that is incompatible. The thing is, its a high gateway and non of the errors point to the gateway being the issue.

So I have a few questions:

1) Should I be able to use lane assist without ACC even though my car has an ACC radar?
2) Does anyone have a 3q0 camera successfully working with an original LRR round ACC radar?
3) Has anyone else ever experienced similar errors with lane assist being unavailable, but no significant errors indicating why?
4) Is there any way for me to have more solid information that this is a gateway issue?


Thanks in advance

since you have the old round radar you should have installed the old 5Q0 camera. I did and everything works perfectly.

3Q0 camera only works with newer flat radar.

this has been said several times around...

Thanks for the info!

I feel stupid now, because I somehow missed this bit of information for the last year...
I was originally looking to fit the 5q0 cam as well (I even have one here), but at the last moment I changed my mind and got a windscreen for the 3q0 based on a recommendation from a retrofit specialist.

Given that you have both the 3Q0 and 5Q0 cameras in hand, have you tried opening them up and swapping the camera / circuit board from the 5Q0 to the 3Q0 aluminum housing?

That's going to be my first move, I think (I posted in the lonnnnnng retrofit thread about my trainwreck of a retrofit). Provided the housing's connector is located similarly between the 3Q0 and 5Q0 - and visually, at least they're close and in the same orientation - I'm cautiously optimistic (while awaiting China Post to get my 3Q0 camera and wiring harness to me).

Hi David, did you replace the round radar with a flat radar? The reason I'm asking is because I had the round radar and it stopped working. After speaking to a guy on Facebook he convinced me I could get the flat radar to work, we quickly realised the 3Q0 MRREVO14F would not work with my abs module so decided to try a 5Q0 MRR1PLUS Radar. This time it worked, but as soon as I touched the distance control on the top of the stalk it stopped working. After investigating it on odis the flat radar is fried! So I'm wondered can it be done or was it coding to blame?
