Intermittent idle issue

Hi there,

I am having an issue on my car that I would like some help/pointers with.

When idling for a minute or so the throttle sometimes closes very shortly and causes a drop in RPM (almost stalling). I am using a Bosch type DBW and I already did the auto setup again to no avail.

The DBW Out. DC parameter behavior during idle seems abnormal to me but I cant figure out what causes it.

Thanks for your time,

Definitely a weird one… I’ve had a look through the idle settings and the log and there doesn’t appear to be anything obviously wrong (but that doesn’t mean I haven’t overlooked something).

I do find it odd that the idle RPM error constantly shows 0 - That may be causing a strategy issue somewhere in the software.
