I have no particular info on the numbers but I can tell you that there is no way in H that you will find the same Bosch number but different MB numbers. bosch even creats a new number for a part when they sell the same part without the MB number on it.

Every change of any kind gets a new number. Software especially.

Years ago Bosch sent a flier around (to Bosch Service Centers)saying that they would provide no control units till 5 years after a car was produced as they (at that time - at least 15 years ago) couldn't tell until atleast that amount of time the final software the manufacturer intended to call appropriate for that year.

With the current software situation that can change daily.
