W212 CGW boot mode

**FxShaw** · 13th January, 2015, 06:17 PM

I am guessing his eeprom data was corrupt and he got data from another file...put that in and change the vin #?

You have the dump after repair ? maybe we can have a look aswell to see what is changing in eeprom and is preventing everything to work.
So basically you still do the milage ?

cheers

The gateway is in built in the front SAM, basically the front fuse box assembly. There are inside two 9S12XEQ384's. It's just one that gets altered.

Yes I know that, removed fuse box,Sam lots of times, I was asking in post#18 what was the procedure for fixing using arbrites.
Or the definitive method of repairing directly to the micro.

You can read and write eprom with FVDI ( AVDI ) without removing front sam from the car.
