checking mileage

[embmw]

I know from my old e46, that bmw cars memorise real mileage in several ECU
(e46 example: instrument cluster and LSZ). I want to know who are the ECUs from my e90 where real mileage is stored and how can I check it using ISTA.
PS: a list with diferent bmw models and ECUs who memorise real mileage will be the great.

The instrument cluster for sure. And I think probably the CAS, and/or the Footwell module which is what replaced the lamp module.
