I do. I have combed over the coding and cannot find any reference to that limit or increasing it. Only thing in the coding that’s apparent is “expanded restart function” which is set to “active”.

ALG works on that road even in poor weather conditions.

What behaviour does it have in stop/go traffic or haven't you tried that because that is the specific question being asked and always has been.

It steers, accelerates and stops...within the bounds of the system. After more than 3 seconds I have to tap the accelerator or res button to resume ACC.

I’ve lost count of the number of videos I’ve watched and all of them show the same thing...3 second timeout on acc in traffic.

Ah, I get it now, my ALG does indeed go down to 0 when I have the ACC activated, there's a 30mph limit with speed cameras near me that I go through with ACC on so I don't get a fine and the ALG is working, whereas most other roads I drive without the ACC so never noticed, thanks for pointing it out

also noticed the "ACC ready to start" message goes out when the engine stops if stop/start is engaged

I am working on comparing the coding of some of the modules from MY17 cars with standard ACC and ALG with cars that have TJA (or at least ALG that works below 65kmh). I have already spotted a few differences but would really like to get copies from more cars that with this feature working. If anyone else can send me these can you please PM me?

Do you have access to OBDeleven or VCDS so you can take a backup of module A5, 13 & 09? Thanks.
