Are there any special steps to take to read the OBD codes on a newer Mercedes? I tried a regular Innova scan tool on my 2021 CLA45 and it stated there was an error connecting to OBD and couldn't read anything. So I bought an iCarsoft MB 3.0 thinking maybe the car needs a Mercedes specific tool... and it can't read OBD either! It keeps giving a connection error. But oddly enough it will scan other components of the car's computers through a diagnostic option.

I'd really like to scan for OBD codes on my car... any tips???

Yeah that's what's weird. This is their latest device... it came out after the current gen A/CLA came out... so I figured it would be good to go. But nope... needed a software update.

I need to spend some time playing with the device. I have no current codes.... but something weird happened in the past so I want to see if there's any codes associated with that event. I noticed the device also reads "historic" codes.

Can you pull gearbox temp data with the new icarsoft?

So I checked and I didn't see transmission temperature in the live data values the iCarsoft device displays. But my car does show transmission temperatures on the in car screens (MBUX).
