Hi everyone, received my VCDS package at the weekend and have finally put it to use!

So, today I noticed that the DRL/sidelights on my 2012 Caddy van were behaving strangely (to me, at least).

When the light switch is off (engine running) the DRL's are on. When the switch is moved to the next position, the DRL's dim. All normal so far. However, when I move the switch to the final position, the main (H4) lights come on and the
DRL/sidelights switch off completely. It makes no difference whether the main lights are dipped or not. I've had the van since October last year, but I've never actually looked at the lights before - perhaps this is normal for VW?

I ran an autoscan and got the following. I noticed the DTC on the CAN gateway, although some (quick) Googling has suggested that the installation list could be wrong (note the second DTC for the Radio - my van doesn't have a VW head unit installed).

Any advice is greatly appreciated!

P.S, hope this is in the right place!

Hi and welcome.

I ran an autoscan and got the following. I noticed the DTC on the CAN gateway, although some (quick) Googling has suggested that the installation list could be wrong (note the second DTC for the Radio - my van doesn't have a VW head unit installed).
Yes, if you have an aftermarket head unit, you'll never get things completely free of faults.

As for the behavior of your lights, I can't say. We don't get Caddy vans here, and our lighting standards are rather different as well. Hopefully someone from the UK will chime in.

Go into Address 19: CAN Gateway > Installation List > then uncheck 56 - Radio. Save etc. The CAN Gateway is the only module complaining, so this should allow you to clear the fault code.

Are your DRLs filament lamps? If so, I think this is desired behaviour.

"Not Registered" means it's already not checked. If that gets reversed (checked), then there will be one or more "Can't be reached" faults. Like I said, there's no way to get things completely happy with an aftermarket head unit. The Gateway knows there's something there, but that something doesn't behave like a factory radio.

Thanks for the advice guys, much appreciated! I checked the installation list today and it is indeed already unchecked, clearly the previous owner was trying to clear all the DTC's too :).

I also spent the drive home from work looking for other Caddy vans coming the other way, so I could check their lights. They were all displaying the same behaviour as mine, so I'd say Zenerdiode is correct!
