What for Mercedes DoIP W222 diagnosis? Looking for a Mercedes diagnostic tool, supports W222 model new DoIT system with DoIP complaint…
You can have a SDconnect C4 (genuine better) or Xentry Connect C5 (clone or genuine..both ok)
SD connect C4 DoIP: you need rework
If you have an original SDconnect C4, you have luck with DoIP diagnosis.
If you have a clone SD connect C4, usually you fail to DoIP diagnosis and XENTRY will report an error message “Initialization of the multiplexer has failed” and fail to go further.
But it doesn’t mean that you have no luck with DoIP.
Go for PCB rework…
The difference between DoIP and non-DoIP is pcb with Ethernet switch or not.
So, you have access to DoIP if you can solder the missing connector inside SDconnect.
You need: DoIP piggyback board, power board and new DoIP cable.
Also, maybe you can convert TCp/IP DLL to DoIP (Ethernet) using some SD Connect PCB add-on and firmware update via SD slot! Display picture below. But it comes to taking risk if it is not well connected.
Note that experienced tech is required to PCB rework; otherwise, you would damage your device- TRYING ON YOUR OWN RISK.
Xentry Connect C5 DoIP: 100% success.
With a XENTRY Connect C5, clone or original, you’ll have good success of DoIP diagnosis.
Original XENTRY Connect C5 DoIP is the best choice to diagnose and program Mercedes newer models like W222.
Xentry Connect C5, 1:1 clone of the original, also works good with W222 DoIP diagnosis
Note that this C5 must be the real version, not the fake one with boards same as SD Connect C4.
A real Xentry Connect C5 should have PCB as follows
