Then click “Step2”, wait a minute and you will see “Perform SCN coding completed”. Click “SCN coding”, you can see two steps.Ĭlick “Step1”, soon you will see “Get SCN data from sever completed”. Click “Programming” on main menu, next click “ME-SFI-Gasoline engine control”.Ĭlick “Control module programming”→ “NEXT”→ “OK”→ “OK”. Then turn on ignition and wait a minute to read VIN. Next start Autel MS908P and choose “Diagnostics”→ “Benz”→ “Automatic selection” You should first connect Autel MS908P to J2534 ECU programming device and Benz car. How use Autel MS908P to do MB SCN coding in 3 steps? When replacing or flashing ME control unit or new Transmission control unit we must get new SCN, that is to say SCN coding. As you know, Benz SCN Coding Service will charge about $150 one time, but with MS908P you can do it at your fingertips!

The cluster changes will only get wiped out if the dealer specifically SCN codes the cluster – they do not do that as part of a service, its a slightly complicated procedure and they all work on the ‘don’t touch what is not broken’ principle.This blog will show you how to do Mercedes SCN coding in 3 steps by Autel MaxiSys Pro MS908P. This is another piece of dealer hearsay and rumour generating. > cancelled out at your next service after being hooked up to Star.

> Another point they made is if you have mods done then they can be >Also, can anyone recomend an indie near Glos to get these mods done?Īlfie .uk (pm him on this forum) is in Woking – he charges a fixed fee to do as much coding as you want – things like auto-folding mirrors if you have folding mirrors, seat moving away when ignition turned off if you have memory seats, etc. On older cars everything swops when you switch between KM and MPH (i.e the fuel computer switches to l/100km etc), on the new ML you can chose how just that display is.

If you code the car properly you can switch between digital speed or temp in that display, and you can switch between KM and MPH also.

I do not beleive this is true – someone sometime ago called up the DVLA (or whoever is in charge) and got the answer that provided you can display KPH via a ‘switch’ (i.e a software menu) that is fine. > As far as i’m aware, deactivating KPH is illeagal – can anyone confirm this? Also the addition of gallons remaining in the tank in the fuel computer needs the same. This needs the factory mode password and a knowledge of German. This does not need SCN coding even on A/ML as it is in fact is not setup in the cluster.Ģ – UK variant deactivation ie Outside temp in place of KPH The engine management systems are all SCN coded – have been for some time – i think that is about emissions compliance as-well as making same control units work for multiple models with same engine but with different power outputs Getting FDOK updated is a whole load more complicated. You don’t have to be a main dealer for SCN coding – you have to have a genuine star machine and be registered with the local country operation properly. You only SCN code a control unit if something has gone wrong (i.e new cluster) or you add something (such as sat nav) and the MB database needs to be updated first. The SCN code is generated from the database that knows what options your car has at MB called FDOK. SCN coding does not apply to the W203 C class cluster, for the instrument cluster it came in with the ML and new A class and basically makes coding simple and mostly non-flexible for dealers, in that the SCN code is only downloadable from MB systems and you have to have a genuine star machine to get access to the MB systems. The more experienced technicians will have had to do this at some point before. Once in factory mode you get extra menues – mostly in German and normally used with assistance from Germany. Star has a password that changes monthly to enable ‘factory’ mode, which gives you the ability to fix things that the normal coding doesnt do.
