MAF (P0101) and EGR (P0401) Faults – Looking for Advice

Hi all,

I'm looking for a bit of advice on my 2013 Skoda Octavia Mk3 vRS 2.0 CUPA engine.

I'm getting fault codes P0101 (MAF sensor range/performance) and P0401 (EGR insufficient flow).

Has anyone experienced these two fault codes together? Could one fault be causing the other, and what would you recommend checking first?

I'm thinking maybe an Egr that is sticking open, so maybe trying to remove and clean it might help, are there any good guides for my particular engine?

Any advice or common causes would be greatly appreciated.

Thanks!
