Thanks. Made the change to the 4Motion. will see how it drives. If anyone is looking for it with OBDEleven, it is 22 - All Wheel Drive, Adaptation - Acoustic measure wiring logic... change from Standard to Increase Traction

EDIT
Just took a quick drive and can fee the difference. Just pulling out of our street which is uphill, Normally, it would feel like a front wheel drive car that would get a late assist from the 4 motion as I was almost fully out from my road. Now, I can fee what seems like an added push from the rear right from the start of me pulling out.

The question will be, what effect this has on mpg.
It's been 10 months since you posted this mod. I was wondering if there is an update?
Here is my dilemma: If you assume that the vehicle will operate no more than 10 to 20 per cent of the time in FWD and you were an engineer designing the 4Motion system, you would opt for a less robust system. I had AWD cars and trucks in the past and the ride much more enjoyable, but these were designed for constant AWD. Comments?

Correction: I meant 10 to 20 % in RWD

The AWD change folks are making is doing zero. I've logged it extensively. Haldex is just a pump and a clutch and the only way to modify the engagement is through a tune (United Motorsport - have it on my GSW and it's fantastic) or a Haldex controller that you use an app on your phone to control. I will post the link to my testing and logging on this mod. My take is 100% placebo/it's not doing what folks think.

I've read all sorts of things folks think this does from "100% 50/50 awd" which is just not possible or the pump would burn up. Also, the way the Haldex works normally is as soon as you touch the gas, the pump activates at some level...more gas = more torque transferred to the rear. When you are cruising, the pump is nearly off so almost 100% fwd. Also an interesting before/after the United tune graph showing more torque transferred if anyone is interested (on my Sportwagen) - keep in mind this only impacts things if you have tuned your car/increased power levels.

It sounds like vaporware to me. I've seen so many of these performance add ons and I have yet to find one that is worth the money. If you want to increase power (torque) you need to change the mechanicals. My two cents

Any idea where to go in odb11 in order to enable side assist (blind spot monitoring) when I have something plugged in to the tow electronics port? I have a bully step with an LED light, but when I plug it in the car thinks I’m towing something and disables blind spot monitoring. Any ideas? Thx! Also, thanks for this thread and list. It has really allowed me to make the car fit my needs even more.

Thought I’d add this resource (link below)...coding mentioned is focused in improving throttle response and overall better acceleration behavior from a stand still (not saying increase power/torque). Atlas models with 4motion will get the most advantage but its also helpful on FWD models.

A couple of the options are already mentioned in the master list above but there are a couple not listed like the 4 motion being coded for improved traction which basically tells the haldex to engage sooner making the Atlas feel and behave like an AWD from the getgo.

Hi, Thank you so much for all these very helpful tricks and info.
You seem to have a good knowledge of these coding and I just wanted to ask if you are able to help with the DRLs, as they turn off with signals, is there a way to keep them on all time or at least get to dimme to a lower value.

Thanks

I thought drl are switch backs and can't be kept on

Another mod doc for your pleasure, all performed using OBD11. Items checked have been performed on my 2019 SEL Atlas. Other items per color coding come from my prior 2019 SEL-P R Line Tiguan, but being on the MQB platform most if not all can be performed on SEL-P Atlas models. Red section at the end are off a Russian site and need testing at some point. Also someone in the thread looking to keep the DRLs on and I don’t believe that is achievable due to some functions controlled by LCM and aren’t accessible. Discussed in a Ross-Tech thread specifically about the headlights on the MK1 Atlas.

So, that doc links to the OBD11 forum and mentions trailer assist for the Tiguan.


Any chance this would work for the Atlas as well? Can't seem to find anything about trailer assist on the Atlas.
