Used CGDI MB programmer to do Mercedes Benz W211 FBS3 mileage repair on bench via OBD cable.
What to use?
Use the USB cable to connect CGDI MB host
Connect the power supply to the harness.
One EIS it is 211545 tab
The gateway for A211
ELV which is pulled from the car.
Let’s go for the procedure
- Read EIS data
- Then go to “Mileage Repair” page, there are 6 operation tips to follow, just read them one by one. There are EIS mileage (KM) and dashboard mileage (KM) in the middle area.
Therefore, we need to erase the EIS by clicking on “Wipe the EIS”, then the EIS mileage will be there though, and we can change the dashboard mileage and write mileage. After that, the dashboard can be input into the car.
- Before doing everything, go to “Gateway” read and save the EEPROM and Flash.
Select W211 and then “Read” the EEPROM ( It will be soon to read the EEPROM, but it will take almost one hour to read Flash.), then click on “Save”.
- Next is to read and save the Flash data for W211 gateway.
This operation takes a long time, please connect the power supply or start the car in advance!
The chip type to read and write is 29F400(512K) or 29F800(1M), when you write back, please make sure the chip type is correct.
- Back to the option “Mileage repair”.
Firstly, click on “Read Mileage” to get the dashboard number and mileage gateway number, EIS mileage.
Then, we have EIS mileage 0 and dashboard mileage 8864KM.
we need to erase the EIS mileage to 0, in case of the EIS mileage come back to the dashboard mileage.
Next is to write mileage(KM) as 11111.
Before selecting the dashboard type “S-classs(W211), CL(216)”, the options “Load Gateway EE” and “Load Gateway Flash” is not enabled.
Okay, next is to click “OK” and “Yes” to block the odometer synchronization with the EIS control module.
If it failed to write, just pull out the power and the USB cable, then do it again.
Alright, write dashboard success! Remove Fuse or disconnect battery!
Ok, remove the power and connect it again.
And read the mileage again, here you can see, the dashboard mileage is 11104(KM).
If the dashboard mileage become 9999, just back to “Gateway” option to write the old gateway back, it will repair it.
Okay, that’s all, hope it helps!
Thanks to CGDI MB programmer, it is easy to use to read and write the dashboard mileage for W211.
