Tips and guides are collected here from experienced users, for purpose of helping those looking for a decent multiplexer for coding/programmings and diagnosis Mercedes from 2005-2019.
The best solution can be….
You will need K-Line support for 2005 and DoIP for 2019 vehicles.
If you have the money, buy the latest bosch VCI. It will cover k-line to DOIP.
But Bosch VCI until now works only with SMR with Vediamo and DTS.
Or you buy sd connect with doip upgrade.
Or you buy sd connect c4 Chinese clone for Kline and ecom for the doip stuff of the new cars
Or you buy sd connect c5 China clone – worked for both K-Line and Doip for Mercedes 2000-2018 (possible for the future vehicles also if software is updated)
This is for your information.
You can rework sd connect c4 to work for Doip also.
The difference between DoIP and non-DoIP is pcb with Ethernet switch or not.
For SDConnect C4 china clone: rework and update to DoIP
Here is a parts kit to upgrade your SDConnect to DoIP:
DoIP piggyback board, power board and new DoIP cable.
If your SDConnect is china made you have to solder one missing connector.
What has been done:
Side metal covers replaced
Top plastic cover replaced
