Hi all,

This topic is meant as a guide for everyone that want to mess around with VCDS and the Beetle... at the moment, it's not as supported as the MKV Golf/Rabbit/GTI, but who know's what the future will bring. I will gather all knowledge I have in this first post, and update whenever I find something new. Mods can make this a sticky, if they want to.

Feel free to share your own experiences, and I will update this post with your useful stuff.


The following are all tested to work with the Beetle 5C. Some things might or might not work, depending on your specific model and option packages. I'm not sure if changing stuff will void your warranty, so let me just warn you: be careful, I'm not responsible for any damage, nor is vwvortex :D.

Blue = undocumented feature!

About the parking lights, so tail and turn signals lit while running?

On my Golf I could mute the phone using the bottom button on left arm of the steering wheel, it does not seem to function on my Beetle.

It is interesting that it has a setting for RVC!

My Beetle tells me "Welcome to your BEETLE!" and I am in Georgia, I do think it should have a y'all in there somewhere, but it is friendly outside of Canada as well

So you tried the coding? I have the halogens. On other VAG products the coming home feature only works the fog lights and tail lights. not the headlights.

yes , i tired it on my 12 TB..... on my MKV GTI u can set the coming and leaving home are on the DRL.. so if u DRLs are Fog then coming and leaving home will turn on the Fog light

but on the Bettle it just dont work... maybe i havent tired hard enough

also u can set the Fog stay on with Highbeam on the Beetle

Not the turn signals, but the parking lights on the front. On Xenon, this will mean the DRL leds are on.
