Clear Permanent Code? or No?

[Plexis]

I had to replace a MAF sensor after it generated a permanent error code for my F10. Previously when I had a permanent code for my E60 I would take it to my friends shop and he could clear all errors without issue. I went to a local small euro shop yesterday that could not clear the code. He told me that it has to be driven a number of cycles before it resolves.

Is this true?

Does most advanced code readers (dealer) still have the ability to clear all codes immediatly?

Thanks

You can erase errors using ISTA.
Also, the Bimerlink application is on the phone and you need a Bluetooth adapter such as ELM, XHP, Bootmod.
You can also programmatically completely remove MAF and then you will not return to this problem. Air will be counted according to MAP

If its permanent, then i dont think just by clearing it will fix it. My m5 f10 also has a permanent code on the mafs after a valvecover gasket replacement. Tried just resetting itu with a scanner, still there since its permanent.

The workshop then do a relearn procedure and reset all adaptations, and etc. And the permanent maf fault went away. Hope this helps.

ISTA can clear any and every error in every single ECU. That’s the only way to clear permanent errors. Just did this on my mother’s 528i a few days ago.

ISTA is the Mack Daddy of all scanners, handhelds, etc. Nothing beats it.
