Cheaper to get it from China. Will cost around 5k - 6k including customs, delivery time less than 10 days.

Thanks Man , I'm keeping Aliexpress as my last resort. I don't mind the cost including customers.

Thing is the VCDS, just like my OBDEleven isn’t going to be in constant use. One might use it over a period of a week to get all tweaks done and fine tuned. So no point in going in for expensive stuff, I feel.

I've the OBD Eleven and facing issues , my plan got deactivated. Getting it fixed. If it didn't come with annual subscription it would've been the perfect solution

Regarding HVAC, its fairly simple, you'll find the option in HVAC long coding.

Got my car back from the detailing shop. I was so excited to do the HVAC tweak. However, facing a major setback.

The VCDS is throwing up an error "Unsupported Vehicle, Please make sure you are running a current version of VCDS"

https://www.team-bhp.com/forum/attac...1&d=1691334029

These are the steps that I followed,

1. As I got the cable from Motoscan, I followed through with them for the software, which they shared immedietely.

Files Provided:
VCDS-Release-21.9.0-Installer
VIIPlusLoader-08.021.10(BETA)-FULL-Installer

2. Installed the loader and vcds 21.9 while the real time virus protection was disabled.

3. The cable firmware was updated.

4. Dragged the VCDS icon on the desktop over to the loader. This opened the VCDS app.

5. Ran the test thingy, Program Options - USB - Test. The test results were as follows while the cable was connected to the car.

https://www.team-bhp.com/forum/attac...1&d=1691334402

Now, I'm not sure what went wrong. I contacted Motoscan promptly. They spent a good 45 mins, re-installing and troubleshooting. They ended up getting the same error. They blamed it on the windows version that I was using. Apparently, it will work on windows 10 and requires some patch for windows 11 which I am finding it hard to believe. They had promised me to have it rectified by the following week.

As you had got the same cable and software version, I could really use some help with the setup. If it can work with kushaq, why not slavia? makes me wonder. Wondering if you had done anything differently from what I did. I really want this to work.

Also, if anyone from Chennai has a VCDS cable, I could use some help with the Auto HVAC Tweak while I get this sorted.

I’d try reinstalling the drivers, but via installing unsigned driver mode and trying again.

I don’t have a VCDS, but have OBDEleven and will be happy to tweak your AC for you. I live on the ECR - Panaiyur though.

Update VCDS version, I am currently using v23.3 and cable works perfectly on Slavia. I was having issues when I was on v21.9.

I'll try the unsigned driver Installation method today.

Thank you for the invite. I'll take you up on that offer. How do we meet? I got the email vcard in my profile.

What is the VII Plus loader version that you are using? The team from Motoscan did try updating the VCDS to v23.3. While the cable was connected through USB port and glowing blue, the VCDS app wanted to update the firmware of the cable.

If possible email me the loader and VCDS version provided with your cable. I believe this firmware update is done through the loader for cloned copies of the cable. I'm waiting for their team to try and troubleshoot this week before I attempt to deviate from the provided software version.

For those who have been running the cable with VCDS 21.9, be careful when you update it to 23.3.1 with a new loader. I guess I have messed up my cable doing so. I installed the above package with the latest loader and it updated the firmware of my cable. With 23.3.1, most of the long coding helper flags for Clima and Cluster are gone and the options are displayed as TNFXXXXXX so you have no idea which byte changes what. In addition to this, security access doesnt work. Now, the double bummer is that I am not able to roll back the firmware to 21.9. .

So for those who are successfully running 21.9, better stick to it as long as it works fine. There is nothing new in the later versions which you are missing out on. I got a few workarounds to try, but havent got the time to do so but it mostly looks like a new cable for me.

label flies might have been overwritten. Update the firmware + VCDS + VIIP loader as well.

The cable firmware was updated using VIIPlusLoader-08.021.10(BETA) which was provided to me by the seller. I haven't tried any other loaders till date. I hope this won't pose a problem.

I had opened the cable to check the number on the chipset. The chipset number is STM32F429. Wondering if you had got the cable using the same chipset. If you don't mind, can you verify the chipset number if possible? As you are using it on your Slavia 1.5, I'm believe mine should also work.


I'm using windows 11 Home Edition x64. Following are the possibilities,

1. Compatibility issues with the loader and the vcds app. BHPian maglev uses the same cable, loader and VCDS combination. It is working well for his Kushaq 1.0 from what I've seen.

2. I must have installed these incorrectly.

Also, are you using windows 11? If possible can you share the the loader that you had used for VCDS v21.9 over email. I'd like to give that a go and see if it works.

Will share the hardware numbers with you as well as the various VCDS versions over drive in a day or so. I am using windows 10 on a rather old Core i3 laptop kept specifically for VCDS and Toyota Techstream.

Fixed almost all the issues. Thanks for suggestions here and by one of my friend who sent some instructions.

I cleared the previous installation completely including logs and old labels since I must have switched between different versions a hundred times.

Then I installed VCDS 23.3.1 and with the option - 32bit program on 64 bit operating system.

Installed the given loader

Now secure access works and I can program everything.

To celebrate this, I changed the throttle response mode using an adaptation available in the steering module. I can't come to terms with how such an adaptation for the engine is actually implemented in the EPS controller. But it does work very evidently.

Default throttle response is somewhat muted in partial press of accelerator pedal. If you press 20-30% the revvs climb slowly and reach the actual intended position commanded by the driver. Only when you press accelerator harder it suddenly surges ahead. With this tweak, throttle response is linear and very direct. This has increased the eagerness to accelerate at any given accelerator input and very linear which requires lesser throttle modulation. And I feel FE has also increased slightly since previously a gentle shove of the accelerator would make the car surge ahead and I had to immediately cut throttle. Now that behaviour is gone and I can control the acceleration better. Have attached this video to show the difference in throttle response. The engine just growls with a gentle press of the accelerator.

Did you reduce RPM to trigger turbo early? If so, I would love to do that as well.

I recently got the same cable from Moto Scan and got it working on Windows 11. The 21.9 they provided did not work, so I found a newer loader and VCDS 23.3.1 and with these, everything is working as expected. If you can DM me a link for cloud storage (still a newbie, I can't DM), I can provide the loader and VCDS installer and you can try. Do note, while installing VCDS, please ensure that the checkbox to run it as 32 bit is selected, only then will it work on Windows 11.

I was trying to get the AC controls on the HU, but I'm unable to find the setting. Can it be done on the 8 inch system of the Slavia? I've seen it enabled by audioholic on the 10 inch one. If it can be done, please help me out with the adaptation/coding for it.
