Since I had a really hard time gathering some popular options to be coded on my Octavia MK4 while avoiding one click apps, I figured it would be nice to post a summary of my findings so far. Some I haven't tested so please do let me know if they work. Would also appreciate if some can be added. It really sucks there is not a big list of features for this car to be coded, one click apps are too expensive.

Would genuinely love to apply a couple of these, however, having read through plenty of posts regarding software issues I'm not keen to start messing about. Would be interesting to hear others thoughts, perhaps those who've applied any of these?

Go here and read through the Golf MK7 Most of theses apply across the platform https://www.autoinstruct.com.au/manufacturer/volkswagen/ Or you can look here. They all work and some have worked on our Kamiq

BEST ALL TIGUAN ELECTRIC MODS.docx

Anyone got any they can add to these? Considering purchasing an OBDEleven unit to try a few of these out...

Ist there a way to make the ambientlight brighter? In my opinion it is too dark and maybe there is a coding for it? Thanks for any help!

Caved in and bought an OBDEleven device + Pro plan in their recent sale...

Have attempted to activate standard cruise control numerous times via the above method but it doesn't work.

I've read elsewhere that you can only do it via One Click Apps, could it be that OBD11 have now blocked you from manually coding it?

Real shame like as I've implemented a few other bits and bobs, some from above and others I found elsewhere. It's a really nifty bit of kit, can't tell you how it feels to no longer have to manually switch off lane assist every time I get in the car 😄

Not really wanting to use One Click Apps after reading in some places that they can cause issues, but if it's now the only way to enable standard CC..... 🫤

what's your car? The Octavia 4 facelift has SFD2 Protection, meaning most of the control units are locked and OBD11 cannot write. Some units can be temporarily unlocked, but it will not work everywhere tho.

I have pre facelift Octavia IV.

I managed to activate standard CC in the end, I didn't realise to make changes on that particular module you have to enter a security code, DOH!
