Default Ecm 644a code on vida

Hi all

Just rescaned the volvo tonight... v70xc 2.4t 2001 with vida and had a ecm 644a code... amongst others.

The HG was replaced over xmas at a garage along with a new rad.
The pcv system and tb cleaned by myself a few months later along with new silicone vac lines

I've read the codes since once complete and did not have the ecm 644a.
While the car drives fine could this be linked to poor/stumbling idle?
What could be the cause?

I'm about to embark on a 500+miles journey tomorrow for a long weekend away... best pack the laptop and vida

Just look up the code in Vida.
It will tell you the possible causes and fixes.
