I have had recent "no start" issues with a Range Rover Sport 2014 (30,000klm). The mass air flows sensors were cleaned at RR service and the problem hasn't reappeared.

I was wanting to be proactive and periodically clean the sensors with a MAF cleaner myself. The question I am asking is what part of the sensor is cleaned since I can't see any visible thermister to clean. The unit is full encased.

Any help would be appreciated.

Follow the wire to the MAF, then remove that whole intake section. From the filter side, there should be 2 small wires mounted horizontally, just spray those down with a MAF cleaner. If they are gunky, maybe agitate it lightly with a q-tip, but be bery gentle, they are fragile. That’s all the cleaning you can do on a MAF. And of course, you have 2 of them, one after each air filter box.
