Topic: MK4 (me7.1.1) Clear DTCs when there are no error codes

I'm late to the Fis-control Mk4 party, but I received mine last week and it's everything I was hoping and more.  I'm curious if it would be possible to add a program to be able to Clear DTCs even if no error codes exist (I think the current UX is proper for most people)?

There are some side-effects of clearing DTCs that are helpful when tuning me7 vehicles.  In particular LTFTs are reset to 0.

Hi,

I added a new user mod "EMPTY DTC". You can enable it at
SETTINGS -> USER MODS
then do
SETTINGS -> SAVE SETTINGS

The new mod will become active the next time you restart the ignition.

You should now be able to also erase empty DTCs.

Here are the new firmware versions:

Please report, if this does work as expected.
