Check Engine..No Codes
2002 E55…had a check engine light come on. Codes were for for shorts in the WS washer/Coolant tank. Cleaned the connections and scanned/cleared codes. Started car had check engine light but scan only turned up 1 code in Pnuematics…B1436-014/Historic (it was in German) says…the safety time of the central locking system was exceeded for the pneumatic branch - passenger door or rear doors. It would not accept a clear code. Started the car..check engine light. Scanned…this time no codes. Started car..check engine light. So now my scan gets no codes but light is still on. Scanner is Carsoft MB1 w/latest updates. Any thoughts would be appreciated…thanks

C1024 - Historic. Fault in CAN communication with component N73 (EIS/EZS) control module
B1103 - Historic. Fault in CAN communication with component N15 (3/ETC) control module or ASG gearshift system
Finally my scanner has hit and miss connection to the TCU. If I unplug and plug back in it sees it but then doesn’t communicate with it. This TCU has been modified about 6 months ago but is working fine
I have no local Mercedes shops to take it to so before I go farther away just looking for some choices. The car has no issues when driving just popped a check lite a few days ago.

After 2 days of clearing code after code…some only appearing after another was cleared the check engine is off… I did remove the TCU and clean the connectors because the TCU was not showing up in the scan. So no real answer.
