Hello All, I hope I am putting this in the right place. I'm currently working with tech support, but wanted to see if any of you had any suggestions.
I have a 2004 c230 K that has/had a few errors. It had an srs light, has an esp light, has occasionally a check engine light.
I bought the crp123 to clear all the errors I could and diagnose what might be wrong. When I connect the crp123 and do the auto scan with odb then it fails on all the connection attempts and can't talk to my Benz. When I did a manual check and select the Benz > 203-c Class (up to 08/2003)” then I was able to reset the srs error codes. Very awesome! The problem is that I have tried almost every year and model of Mercedes in the crp123 and can't talk to the esp, transmission, or engine. Nothing but the airbag system will respond to the device.
I have a very cheap odb2 Bluetooth device and it can talk to my benz just fine. It lets me clear engine errors and monitor the car.
I have also tried my crp123 on my 2006 Acura MDX and it works perfectly. Talks to every system, automatically connects and is very nice.
So, do any of you have any suggestions? The device works as proved by my acura, it can talk to the Mercedes as proved by the srs error clearing, the odb port on my Benz works as proved by the cheap Bluetooth device, and the crp123 has all the recent updates. Any idea why it won't really communicate with my Benz?
