[C32AMG/02]

I read this post and the first thought I had was, this is one group of paranoid guys, then I started to think about it, if true why would MB actively seek and flag modified cars. Then it hit me, at 54 my brain doesn’t work as fast as it use too, it’s a warranty issue, exceed the HP/ torque rating of the vehicle and components like engines and transmissions start to wear and fail prematurely, an added cost the MB $$$$$$$$

As a transmission tech and shop owner I am always looking for technical information which would aid me in diagnosing my customers’ drivability complaints, in doing so I found this. A MB training technical document.

Flashing and Software Calibration Number ( SCN)

“SCN coding identifies control unit software and coding conforming to vehicle”

SCN is required

* After flashing Fuel control unit (ME) or Electronic transmission controller *

After replacement of ME or ETC

Required by law, can be find if not done

Vehicle may not function correctly if not preformed

* Prevents after market performance enchantments*

In Future additional control modules will require SCN coding


They are also scanning for transmission control module performance enchantments
