Is there a code erase limit?
A young man looking at my Mini at a recent British car show told me that BMW had set a limit on the number of times you can erase codes in the main module, which he called the footwell module because of its location there, and that if code erasures exceed the set limit they can no longer be erased and the only solution then is to buy a new module from Mini for big $$$. He said he'd run into this in his work as a mechanic on BMWs and Minis and to be careful and not erase codes that are not causing a problem so you don't run up against the limit..
Has anyone else experienced this or heard of a limit on code erasures? My 2004 Mini Cooper S JCW has a dozen codes on various lights set even though all the lights seem to be working as they should. It also has two window fuse codes, A1 & A2, although the fuses 1 and 19 check good (might possibly be relevant since both windows no longer dip or go down). There are no OBDII engine codes set, just the mini specific codes scanned with a Schwaben scanner.
I hesitate to erase these light codes until I can find out if there is in fact a limit on code erasures or if such a limit is year or model specific. Anyone heard about this?

I assumed any engine faults would be stored in the ECU, but I don't know where these others are stored.
