I want to give the MAF a clean on a Mark IV Golf and was wondering what to use to do it? I think I read before about some solvent??? Is it just a matter of wiping it with a damp rag? Do I just pop it off and wipe the underside or whats the best way? Anyone done this and if so any help appreciated, Thanks.

best not to actually touch the filament, AFAIK its a hot wire and quite fragile... use Isopropyl alcohol, available in aersol form from Maplins etc...

best you can do is just spray the MAF liberally and allow it to evaporate, this can be doen by either removing the MAF from the housing or just spraying into the intake trunking, leave a least an hour before starting up to make sure all alcohol has gone...

AFAIK replacement MAF is approx 80 yoyos so worst case, replace...

I think its ok, just noticed slight shudder when slowing down, might have used slightly too much oil when I cleaned my air filter so just want to give MAF clean to be sure, thanks for help.

I just had mine replaced 98 euro better off replacing imo! could do more damage and end up worse than it was to begin with. There is a guide how to clean it on uk-mkivs using electrical contact cleaner available from halfords. And if your gonna replace it VW do an exchange, Basically they fix your old one and sell it again. They'll try and charge you an hours labour to change it, Well they tried to charge me until I said I'd do it myself.

I've a spare Merc on which will do the 90/110 engines, but I think you're a PD150 iirc ?

the actual wire is shielded by the rest of the maf housing, you need to take the sensor out of the intake pipe otherwise youre wasting the iso solution.

I spray servisol contact cleaner on mine now and again, still have original MAF and 115k on the clock and it still gave over 200bhp on awesome GTI rollers last saturday

Am...dunno what to do now, think I might just leave it, no point tempting faith! Its the 150 engine so Merc MAF won't work, thanks anyway, I'll have a look at the weekend and let you know how I get on...
