Hi all,

I have a 2004 Mercedes CLK55 which currently has a remap on the ECU. I do not want the remap as it is causing issues so i suspect it wasn't done very well.

I want to reflash the ECU with the original map using DAS.

I have spend the last two weeks, while waiting for my C4 multiplexer, setting up the software on my laptop and doing a lot of research into it but one thing is still not clear.

I have run Xentry simulation to attempt to learn how to do it and after the ECU flash it asks for the SCN coding number. I have read that a car of this age does not require SCN coding. If i am only overwriting the ECU and not replacing it will it require SCN coding? I will be doing all this offline.

I looked into doing it with Vediamo but from what i can gather the C4 multiplexer can not do K-Line programming through Vediamo.

Any help greatly appreciated.
