hi all
i tried to adjust mileage with x300 dp plus tool for mercedes b class w245
now intsrument give 9999999
how can i reset it to last mileage?
thanks

not familiar with the x300 but from my understanding did you leave the tool plugged in to run through the program complete?.

from what ive seen some of these tools program dash to all the 9s to enable the key modules to record the higher figure before then zeroing the clock and then finally programming new mileage.


maybe it didn't finish the program , have you tried again?


it may help.

yes i tired 4-5 times but still same problem.
when i read mileage with the tool it shows mileage that i adjust ,but in instrument gives 999999999

just a thought have you tried disconnecting the battery it may work otherwise you will have to wait for a more firmer answer from someone familiar with the x300

yeah  also disconnected the  battery

when you corrected the mileage does the menu give the option to block syncro with other units or just program? it may be something silly like you didn't block the keybox and so the higher mileage went to the keybox and then overwrote the clocks

no
just read old value and input new value 
nothing more like that

ok well I hope someone comes along with a trick to make it work with x300 or I fear you will have to find someone near your who can block syncro with there equipment or go the route of fitting a blocker for the keybox and then just change mileage on clock .


if you use the search button there is a large topic on the matter but with very conflicting answers im afraid. good luck.
