Hello , thanks for your question in the autoaid Community.
Your described fault Code means:
2203 (001) external amounts of intervention by the ECU N47-5 (ECU ESP and BAS) / N63/1 (ECU DTR) Togglefault
2203 (002) external amounts of intervention by the ECU N47-5 (ECU ESP and BAS) / N63/1 (ECU DTR)
2203 (004) external amounts of intervention by the ECU N47-5 (ECU ESP and BAS) / N63/1 (ECU DTR) moment error
2203 (008) external amounts of intervention by the ECU N47-5 (ECU ESP and BAS) / N63/1 (ECU DTR) plausibility
The Problem comes from the Distronic CU. At the Daimler Dealers the Software could be renewed and the fault got away.
Sometimes the fault Comes from the DTR Sensor in the middle of the watercooler in front of the car.
You could check the wirings and check the plug of the DTR Sensor and from the ESP ECU.
Without a wiring diagram is this fault not so easy to find out.
Just with a wiring diagram this faulty couldn´t find out, this is a Problem that must be there at the same time you measure it.
