Anyone tried this OBD2 Lowering Module?

EDIT: So I purchased one of these recently and thought I would write my full review here. I ordered through the Ebay link above and when the seller found out I was in Canada, he offered to have is Canadian partner send me one. I think they are on the other side of the country, but it still got here in a few days.
The device is super small and compact and plugs into the OBDII port under the dash.
The device is as pictured here (although mine is blue). It plugs into the OBD Port and provides a menu on your COMAND screen allowing you to lower the ride height or return it to stock.
The menu system is straight-forward and simple
On my C218 2016 CLS550, I don't have a touch pad as shown in the video so you navigate using the numeric keypad on the head unit... 2 and 8 are up and down, 4 and 6 are left and right, and 5 is enter. Very straight forward.
The device comes with three options for ride-height:
- Factory
- Low (-32mm)
- Custom (you set the front and rear drop yourself)
There are two menu options:
1. The current setting applied and the setting you want to apply (one of: Factory/Low/Custom)
2. The ride height settings for the custom option (Front drop and Rear drop)
I wanted a drop of about 20mm so I started with a custom setting of -15/-15 and that wasn't enough for me. I ultimately settled on -25 front and -20 rear to get the ride height dialled that I like. This gave me a ride height about 20mm lower than factory. Note that it's not accurate to the mm. I suggest you lower it on a very flat surface and use a yard stick held up to the fender aligned with the wheel hub to measure before/after height. Here's what I found using different custom settings:
Front Left Factory: 690mm (ground to fender on my yardstick)
With Custom -15mm = 677mm (actual drop of 13mm)
With Custom -20mm = 675mm (actual drop of 15mm)
With Custom -25mm = 670 (actual drop of 20mm)
When I asked the seller about the slight discrepancy, he aptly pointed out that the system is only accurate to +/-5mm due to a variety of factors at play in the system, so you may have to play with your custom setting if you're as picky as I am.

I found I had to dial in a -25 setting to get my desired 20mm drop on the front, but only -20mm to get an actual 20mm drop on the rear. You may have to experiment similarly.
The beauty is that this system is so easy to adjust. You can dial in new settings in about 30 seconds and see the results instantly.
The bottom line: This system really does make any other lowering option for Airmatic cars look foolish in comparison. No mechanical work, no wiring, it really couldn't be easier to change settings, or revert to stock any time. I wish all my previous cars had been this easy and affordable to lower.

Feel free to contact the seller for more info. I've exchanged several emails with him and he's a great guy based in Eastern Europe.. He's invested a lot of effort into this product and it shows. He deserves every dollar he makes from this. It's a great device.
Here's how you use it:
- Turn the ignition ON but not the engine
- Insert the device into the OBD port
- The menu will appear on the screen
- Select one of the preconfigured settings or set your own custom setting
- Apply the setting (it will take a few seconds for it to write this to the car)
- Remove the device
- Turn off the ignition
- The next time you start the car (even immediately) it will adjust to the new ride height.
You can have it in whatever mode you want when you start (sport or comfort).
The Sport and Comfort button still works as expected. Sport is still about 10mm lower than Comfort. I will actually use the comfort setting more often now when I have others in the car.
Here's some quick photos of the 20mm drop on my car with my new Rohana RC10 20" wheels (245/35 front, 285/30 rear)...

Let me know if you have any questions, and I'll do my best to answer.

I get that Star changes the calibration values, links fool the height sensors into thinking the car is higher than it is, and inline lowering modules intercept and change the voltage signals from the ride height sensors, but it's hard for me to understand how this might work.

I believe our cars are a little too high. On my C-300 the front is nice and flush so im trying to accomplish that drop with the CLS too. Fingers crossed

Car hasn't moved in about 9 days. Front is definitely dropped but the rear seems regular height?
What do you think


Also, how hard would it be to copy the program on this? I would be willing to give mine to someone who can do it and either release the software online for all of us or give free copies to who wants it?!

back in the day, I paid more than this for HR lowering springs and now I’m getting more flexibility and virtually zero effort for the same price.
As as you can see, I think this is well worth the asking price. In fact, it’s appealing at twice the price he’s asking. So let’s count our blessings here.

I rest my case.
If anyone orders it see if you can pay extra for faster shipping. EBay is estimating this to get here on May 1 lol and I ordered it on March 8Attachment 415983
