Check engine ligth is not on and i have 6 message on the info display but some times i get no message at all, everything works fine.
I can not find some of codes descriptions like p2300,p2310,p2318,p2315.
I clear all the codes last week and tomorrow i will scan the whole system again to see what codes are back on.

Second time scan

After I cleared all the codes and drove around couple days, Scan it again;
ESP (All the codes are back)
C1026/C3250/C1552/C1020/C1116/C3266/C1938/C1531
When I was driven with the scanner hooked up monitor the all 4 wheel speed sensor and steering angle sensor, front rigt whell speed sensor fail 2 times for few seconds and showed zero at 45-50mph, now i am going to inspect the sensor, teeth ring and electrical connections.
AIR BAG(only 2 of them back)
B1013 F.driver seat belt buckle
B1023 F.passenger seat belt buckle
Overhead Control Panel
B1204 Rain sensor intermittent
Steering Control Module
B1334
B1352
Transmission (This are the codes showing Unknowing Codes and I realy want to know what are they)
P2300
P2310
P2318
P2315
I am down to 17 codes

and I am sure once I fix the wheel speed sensor, few ESP codes will disappear.

I removed the front rigth wheel speed sensor, looked ok. Compare the resistance wit left side, they are about the same(399kohm/403kohm). I switch the two sensor and take test drive. They did not fail but tis time rear left and rigth speed sensor fail at the same time for couple seconds. I think ESP module it self going bad.I inspect the wires and plugs looks ok.
I will do some troubleshooting on the ESP Module.
I assume this scanner (Auto Enginuity w/Mercedes Expansion) giving me the accurate information. I did not see to much review about it.
If anyone use the same scanner, I would like to know how well its working.

Today I Replaced the Steering angle sensor(P/N A1645458716 if anyone needs it). That Cleared up code B1334 and B1352 so don`t have any more codes for Steering Control Module.

. I don`t get "Run Flat Inoperative" message on the secreen and triangle ESP indicator on the cluster is off.
