To be honest I don't know if the MAF needs to be coded when renewed. Having said that like yourself I have heard of many MAF units being replaced without the need for programing.
On the other hand the MAF may be perfectly OK and the fault is elsewhere but by making the ECU go into default mode it by-passes the problem.

It may be prudent to seek advice form a diesel specialist rather than go to Renault
