Never had to flash anything in preLCI F10. If TMS is good you need only to initialize it.

RE: TMS FRM3 F10 Coding issue
Thats what I thought as well, but reading other posts this problem seem to appear due to ISTA+ expecting a new TCM when initializing - it even states when trying to initialize that you need new tcm, not used. So I am pretty certain that the TCM´s that are used get some form of info written when they are initialized the first time. If that block already is occupied ista wont initalize. On newer cars I never have come across this issue. Easy peasy with esys just inject cafd and then initialize.

I ordered two new units from BMW at 400$ a piece. Exactly same numbers on TMS. With these ones the initialization went fine directly. So car is fixed.

No problems at all. Can we agree that there is something that needs to be done with used TMS on cars with FRM as upposed to those which have the TMS in the ECU tree in Esys?

Found this thread that seems to be onto something but missing arguments to get it running. The car is fixed now but still want to find out what needs to be done wink https://www.bimmerfest.com/threads/used-...ci.962391/

I have had this issue since. Used lights on pre-lci would always have adaptive light error. Flashing and coding does not resolve even though lights work. Adaptive function obviously would not. No solution so far.

On LCI it is easy to flash the TMS so presents no big problem.

Finally, I am not the only one smile

I did have an idea of mounting the used TMS in a LCI, code default values and then back to pre lci, could work. But a bit of a hassle..

I think they might have vin in the prelci so coding alone would not help. Saw some posts about some one who claimed he could resolve but the trail went cold. Since then I just get new TMS for pre LCI lights. Easy, quick.

RE: TMS FRM3 F10 Coding issue
Ok, a little update, it is possible to virginize these quite simple - hook it up to a LCI car, code to default in ista, read fdl so that vin is removed. Then it works to use as "new" in pre LCI also. Should work with a bench setup with fem module. so SOLVED.
