Assuming you have the same model, the first thing to check is the EGR valve for sticking . That is code 5 and they have up-graded the egr valve due to sticking. [ Benz TSB]
At the same time , check for air flow through the egr to intake
pipe... another common code 5 tripper..
From there , I would clear codes and run it to see if 10 pops
again before condemning the MAF sensor [ 10 ].
