- 2012 W204 C220 CDI AMG SPORT
Hello everyone!
Very new to the forum! I have recently purchased a 2012 W204 C220 CDi AMG sport, its my first Mercedes and im absolutely in love with it.
I have noticed the stop/start doesn't work and the ECO either stays amber or disappears. I do know the system needs certain correct parameters to work and can be a waste of time.
The car is very low miles with little use so I can understand the batteries being no good. Main battery has been replaced recently however I have tested both main and aux batteries. Aux battery failed so has been replaced......stop/start still not working!
I had a DTC system scan today with a snap on verus and I have C1207 - There is an internal fault in control unit N30/4. I have no ABS/ESP faults or warning lights. Now this to me indicates a ABS pump fault however when searching for the code online it relates to a stop lamp switch fault. Can anyone on here confirm what the code is related to?
I know if there is a fault in the braking/abs system the stop/start will not work so I feel this is my cause for the lack of stop/start.
Any help/info will be much appreciated.
