2013 A180 (W176) Mass Air Flow (MAF) Sensor Issue

[divettri]

Hi, after some advice / help....

Replaced Air Filter approx.6-months ago & almost instantly had Mass Air Flow (MAF) sensor warnings & Engine Mgmt Light on. Cleared them with diagnostic tool but they come back on after short time.

Yesterday, replaced the MAF itself, reset all the diagnostics but only drive the car for 7-miles before warnings came up again.......

Am I missing something here or can someone help print me in right direction as to a fix? Fault codes are attached in images.

Does your version of the car need the air filters reset via Star when they are changed?

Hi sorry but I have no clue. Never had this issue with any other vehicle I've owned, merc or other.

Whilst the vehicle was in the garage having the steering lock replaced, the technician advised that he could hear air rushing within the engine somewhere. Unfortunately, he didn't have time to look into this issue at the time & we also needed the vehicle back.

He suggested that maybe we can get a smoke machine / can to check for any air leaks. Can someone advise where I can get a smoke can or where (other than the obvious) to look for an air leak?
