Mileage Correction

[TheTearaway]

Hi people.

If somebody would be so kind as to help me with advice I would be very appreciative.
I have a 2015 Mercedes Sprinter 311 CDI 906 that requires the mileage correcting due to a new dash being fitted. I have Xentry/Das and have worked with Sprinters for many years, and thats where my knowledge ends to be fair.
1. Can I buy a correction tool for the 2015 906's
2. Do I have to remove the eeprom
3. Do I have to remove the EIS

Any knowledge shared will be hugely welcome and appreciated.

Thanks in advance.
