Fully agree that any pure cleaner will do the job on the filaments and the thermistor but you have to consider the effect on the plastic housing. Do the active ingredients melt plastic? Not sure that all brake cleaners are cleared for use on plastic housings but, you pays your money and you takes your choice.

Update. Did a long run this weekend. No coughs, no misfires and got 42 mpg. Thanks to all.

I just got 38MPG out of my 2.0 HDI. Mixture of around town driving and some longish 100 mile motorway runs. Slightly skewed by idling for 20 minutes or so 2 or 3 times when I was out camping in her and it was bloody freezing!
I may try a MAF clean to see if I can get a few more mpg, I was hoping for mid-40s.

For what its worth (is that fwiw in internet speak?) the 2.0 90 BHP does not have intercooler.
BTW (yes I know this one). I normally get 600 miles to a tank of diesel. But that is little traffic idling.

Cleaning the MAF will not improve your MPG, it's either working or it's not. You'll know if it's not working as the car will not rev out or pull cleanly. I had no success cleaning mine and had to replace it at a cost of about £35 I think it was. Well worth it to have the performance back but it worked well just disconnecting it as a stop gap.
So where does this bit go then ?

Beg to differ on the working or not. Cleaning improved my fuel consumption and cured the hesitation, misfire/cutout. On the other hand, if the MAF has failed, either by broken heating wires or a falied thermistor, no amount of cleaning will save it. Contamination on the wires will insulate them, reducing the heating effect, contamination on the thermistor will reduce its sensitivity. No way of telling which will work, cleaning or replacement unless tried. Agree on the diconnect the MAF disconnect first though, confirms where the problem is. You pays your money and you takes your choice.
