It asks for discs after selecting online. The computer has internet access and it works. I have not tried coding on newer car with xentry.
IF I try doing SCN coding, it does the same with this message:

Bought my car from the auction, run and start fine when I try to move it out of the parking so the tow truck can tow it to my shop.

No damaged to front end or steering wheel when at the site. After the tow truck tow it to my shop with the dolly, only tow rear wheel but not locking the steering wheel with seatbelt. The Mercedes Scan Tool will not start, no crank I can turn the car to all the way but no thing happen !

Jump start but still cant start ! Check the battery, still have good voltage

Steering wheel just locked, can’t move ?! Lock like something prevent the steering wheel so the key not working

How to Change MB Star DAS Xentry Start Picture

It’s a customer interesting setup on changing a picture of Mercedes Benz Diagnostic Tool DAS XENTRY software interface. Here is what he shared for all:

I was playing around with DAS the other day, changing things when i came across a picture of Xentry
So i decided to change it and it worked…
I think you guys can change it so that it displays your shop logo every time you start DAS or picture that you like.
It takes couple of tries but once perfected it can be used on other systems as well
When you change it, just make sure it’s confined to standards such as

File must be in location C:\Program Files\Mercedes-Benz\DAS\bin
File name must be “XentryDAS 991×620.bmp”
File must be in “bmp” format or Bitmap image (.bmp)
Width must be 991
Height must be 620
