EGR fault. Stood still too long?

[TeaVR]

My car's been sat still for a few weeks. When I eventually got round to starting it, it popped up an engine warning (amber light).

I purchased an ODB2 reader, and it shows an EGR fault code. I reset the error.

I've driven a couple of hours since and the warning hasn't returned.

So, could it have been the case that the car had just been sitting still too long or am I being too optimistic?

(Car is a 2012 Volvo S60 D3)

Many thanks,

Don't worry about it unless & until the problem comes back.
