Hi!

So I'm one year deep into owning a 2015 passat now, and I've just recently bought my own HEX-V2 after borrowing a friends old VCDS adapter a few times.

The car doesn't really have any problem that shows other than in periods the front assist stops working, and therefore the cruise control works only in limiter mode. (which sucks)
This is a bit annoying since I always use cruise control. I could live without the adaptive cruise, but not live with being limited to speed limiter.

So I started checking this out, and was led into calibration of the radar as probable cause, but I couldn´t figure out how to initiate a calibration.
But I did also see a lot of other errors, many stating missing messages and such. So I abandoned my tries of calibration and just cleared all codes.
And now everything started working again!

And from then I have found it can work for months, and if it starts glitching a clear of codes "fixes" it again.

So now I'm thinking that maybe a misbehaving module or connection or something is causing problems that makes the more sensitive systems to go into safe mode and shuts down?

Attached is a scan with codes that have occurred in just 260km's. (sorry for it being in swedish, I can redo a scan in english if you want)

Am I on the wrong track of maybe a glitching module or bad connection that may cause this?

Also, in the car menu, under driver assists, there´s a option for traffic-sign assistant. But I'm 99,9% sure I don't have a camera for that.
There is a slight chance I have coded that, since I have read about it, but now I can't find where do de-program it..

/Anders

Can you please do the autoscan with english version of VCDS. There are probably quite less swedish speaking here than english speaking :)

Nothing to with radar itself your problems. Check your trailer wiring, most of the errors are pointing towards your trailer electrics. That will drop out ACC as well when it goes into fault.

Thanks for the reply! :)

I will do a re-scan in english, but I've just cleared all errorcodes so I'll give it a few kilometers to accumulate.
But I suspect there's already a lot of them.

I too am suspecting the trailer module/wiring. But I can't say why and don't want to plant a seed so to speak.
So maybe I'll start by checking around that.
I do a lot of towing and haven't seen the lights on my trailers glitch, but of course I'm not staring at my trailer lights all the time.

Our climate is pretty similar Finland and Sweden and there's a lot of salt on the roads during winters. The socket for the trailer is in a such place that it sucks all the crap from the road. I'm pretty sure the issue is there. It's probably full of water and in worst case it has burned the trailer module. Or has burned the fuse for it and that's why it does not recognize it at all

I will check it out, but last time i towed was like a month ago, and it worked just fine then.
That being said, it can still be some creeping voltages och whatnot.

And yes, we all hate salt. :)

I just did a scan with the english version of VCDS, but there were not many codes yet, and the codes this time from the trailer module was actually correct, a crappy trailer with lot of bulbs broken..

But here's the scan, although i suppose I should wait for some more codes to accumulate.

Here we go, I just had fault again, causing front assist to get scared. :)

Pasted below is a new scan, and once again I was towing the crappy trailer, but also my mint condition caravan.
Both of which were working just fine, except for crappy trailers obviosly broken bulbs..

And I didn't get the front assist fail when towing, that was just when i drove to work.

But it seems like the trailer module is acting up?

Also, as I wrote in my first post:
"Also, in the car menu, under driver assists, there´s a option for traffic-sign assistant. But I'm 99,9% sure I don't have a camera for that.
There is a slight chance I have coded that, since I have read about it, but now I can't find where do de-program it.."
I don't know if this maybe causes issues?

You dont have the A5 camera in the car, so better is to code the TrafficSR out.

Then you have to check the 69 Trailer module on water damage or so(behind left trim/panel in trunk), in the last scan it has a lost-communication

Now it's been a month month or less since I did as suggested.
I disabled the sign-thing in the MMI and now that menu-option isn't there anymore. Since i don't have the camera as Vdub said.

I also checked the module in the trunk, although I didn't really get it out, but i did get a good look in there and did reach and re-plugged the connectors. And by visual inspection, it's looking like it's brand new. Clean, not even dusty, and not a trace of water like specs or corrosion.

And lastly i cleared all error-codes again.

Since then the ACC has been working without a glitch. Except for a backup sensor who finally gave up, but atleast that doesn't affect ACC. But i will change it, someday.

And now when i did a new scan I do actually think that my problems are solved?
Sure, there a few messages still, but as far I can see, they are legit. In example broken sensors and lights on trailers causing other errors.
But no missed messages and no communication.

Holy mothballs, batman!
I actually think I found my issue! :)

The trailer module seemed to have something to do with this, and my car had a real mental breakdown lately so I decided to take a closer look at the module.
Removing it wasn't so hard, and it was clipped together, so even inspecting the PCB was easy. Again, nothing visual to complain about at all, it could pass as a brand new one based on visual.
But, relatively new to me was the press-fit pins to the connectors on the PCB, no solder, just a tight fit in the vias. I get the point of this, but it seems like a cause for problems as well.
So I used some violence on it, tapping, bending, trying to exercise it. And now after a month of driving and then performing an auto-scan, the result was no error at all! Yaay!
(Well, except for my still to change rear parking sensor, but that is to be expected.)

Who's in a rush?

I did actually (mostly) check what you suggested in nov -25, as the post post after yours says. And for a ling time i didn't get any panic-attacks, but then they came back.
And now when I messed with the module again, more thoroughly this time, and "fixed" it again, I can be sure that the module is my problem. And that's why I posted again.
But if it's permanently fixed, that's another question. Time will tell. ;)
