Regards paul....

Thanks Paul you are correct 2nd drive cycle and CEL is back on again. How do I go fixing this what part do I need to checkclean or replace 2 answers I found on the mb forums p2001 Component N153 (ETC control module) is faulty. p2001 Malfunction of exhaust gas recirculation (functional chain)(P0400). I do not have a P0400 code coming out is it the ETC module is this part of the SBC module just had it

will just spit out this message if it detects a certain motherboardfirmware version. I found it very suspect when the rep told me another SLK owner also had to have their control unit replaced because of the same problem. Im going to buy a cheap 3rd party OBDII scanner off ebay and see if it throws out the same code its strange how the engine management light never came on with such a serious fault.

Another odd thing is why have I not seen any warning lights come on the dashboard if the ECU has detected such a serious fault ( Chris First the bad news - NOX traps only applies to Diesel engines
with new module 4.) Reinstsalled old Transfer case module 5.) Checked wiring and plugs inside center console. All checked out ok. Connections tight and clean. p2001 code still not clearing. Still No H on dash. 6.) Performed method as described on this board and other boards to make the H appear on dash. (Tranny to Neutral and press High or Low etc). 7.) Connected Star Diag.

I dont believe they are W210 MB transmission or MB OBD fault codes. The MB OBD engine control unit transmission faults
Had dealer run codes and diagnose boost and tranny codes came up p2001 Charge pressure too low and P2318 One or more messages from control unit N155 (Electronic selector lever module control unit) are not available on the CAN bus. (CAN timeout fault) ---both current and stored. Anyone know what I need to do
