Re: Golf V Estate/Wagon up for discussion | Posts 16+

My awesome, homemade wiring harness had a cold solder joint. Awkward :/

That's embarrassing. Main thing is that it works now .

'So, it worked for me even without a gateway...'

It's not quite finished yet, but I haven't had the time to work on it further.

So, in my case, it also worked without a gateway...

It's not quite as polished yet, but I haven't had the time to work on it further.

Are you sure? That would mean that the combined CAN bus on the instrument cluster has a bit rate detection and downshifts. It normally runs at 500 kbit/s, while the infotainment components like the navigation system or head-up display operate at 100 kbit/s. I tried that once when the Golf V was first released, and at that time, a direct connection didn't work.

Okay, I was even able to communicate with it directly using VCDS...

However, precisely setting the speedometer was not possible. I mean, I couldn't set it to, say, 85 km/h. But it might also be because I didn't send all the necessary data.
Perhaps something from the gateway is needed for that.

Acho so If you only want to address the AI, then you naturally don't need a gateway.

but precisely setting the speedometer was not possible that way. So, I couldn't set it to, say, 85 km/h. But it might also be because I didn't send all the necessary messages.
Perhaps something from the gateway is needed for that.

Okay, I remember that interfacing with the tachometer wasn't a problem at all. My tachometer, however, also doesn't display km/h . I believe that calibrating the speedometer was not so trivial.

Yes, I just want to direct it to the AI.

So, I recall that controlling the tachometer was not a problem at all. My tachometer, however, also doesn't display km/h . I believe that calibrating the speedometer was not so trivial.

Hehe. Well, you know what I mean.

But did you actually manage to steer both of them?
Sure, here's the translation:

'lg' is a German abbreviation that stands for 'liebe Grüße,' which translates to 'best regards' or 'warm greetings' in English.

But did you manage to steer both of them???

Yes, it was an Audi A4 8E with the virtual cockpit, and the issue with the speedometer wasn't entirely clear. It seemed like a specific condition had to be present. I tried to reproduce it consistently, but something else always interfered. You probably know how it is .

I'll try again with my Touran's AI system this weekend.

I had tried to make it clearly reproducible, but then something else got in the way again.
You surely know how it is .

Yes, I'm probably all too familiar with that.
I experienced the same thing. It would sometimes accept my commands, but then after a few seconds, it would disconnect again, and I wouldn't be able to do anything.

P.ostrich - You wrote that you can click through the menu using the speedometer displayed on the table. What was the part number you used?

'I have one unit from a Touran 1T0-920-873D (production date 2007) and one from a Passat 3C 3C0-920-970H (production date 2005). Both should be comparable in terms of CAN bus communication. I can get various warning LEDs to light up, but unfortunately, I can't navigate through the menu. Have you connected anything else? For example, have you pulled any pins to ground?' I suspect it's probably due to the active WFS.
