another thing wd40 will it work???

i think the way it sorted my issues is by taking up space in the connector where air usually sits. so to work it has to be gooey.

its nasty stuff full of cancer causing chems that you dont want on your skin, and its not in the shops so to speak. its a different product to normal grease so i doubt anything else will work in the same way.

some may say lala land....
@traumapat, just applied mine and having bought two tubes of the stuff have a feeling this will last for years, or did i not apply enough, so:

How much of that stuff from a tube should i be using in an application?

[edit]
have applied this to the MAF and feel it has made a difference;
seems smoother when starting and pulling of the drive in morning
seems more response when in gear and accelerate
think less smoke, but rear windscreen is filthy so hard to tell

just need to locate, be told, where & what else i can apply it to....

I did mine and any other connector i could get off, isopropyl alcohol first then applied the grease, packed the end of the female connector and put on, done this a few times and then plugged in.

I'm using "high density polysynthetic silver thermal compund" instead of "silicon grease". It is far more stable and conducts eletricity itself. Silicon grease doesn't.

3.5 grams costs about 8 euros.

It is expensive but worth it. Some silicon greases crumble into dust in time, some dissolves in heat etc.

I am now using that stuff, a sparky recommended to me. It seems to work even better than silicone grease.
I have some silicone grease going spare if anyone wants it just PM me.

Are you sure you want a better conductor of electricity? I thought the purpose was to isolate the connections from spurious electronic signals.

No... :cartman:

The Silver Stuff must be carefully inserted so that it won't make a shortcut. And so it stabilizes the signals under extreme conditions :lol:

The whole "silicon grease method" is full of bull and just won't make a difference - just a little mess. Forget it. :funk:

Very funny thread although, lets stop teasing ppl ok because some are believing it and actually sticking some silicone grease in the connectors - as if VW wouldn't have done it in the factory if it was any good. :banned:

I never noticed any difference with dielectric grease -- no improvement and no degradation. However, I started with a new MAF sensor at around 33k miles, tried the dielectric grease somewhere around 60k or 70k miles, and finally replaced that MAF sensor one week ago at around 280k miles.

No one has ever heard of a MAF lasting so long, at least one that was regularly checked with VAG-COM and shown to be working properly. In fact I did not throw it away, I will keep it as a spare.

Did the dielectric grease contribute to a long life for the MAF sensor? There isn't any way to tell.

Gonna give this a go on my 2.0 TDi which has been hesitant on idle and thought some of the gears.

Got a tube from maplin & after being a bit sceptical I can say that it seems to have reduced the amount of smoke on startup (or is that me just letting the glowplugs heat for a second or two longer).
Not sure about smoothness, will let you know in a week.

I added some silicone dielectric compound (purchased from eBay) 3 months ago and not noticed any immediate difference or short term difference. However i had no issues to begin with. Will wait to the colder mornings to see if the car blows some soot out on start up...

The glowplugs won't even be working in the summer months - the temperature needs to go below a specific level before the plugs are activated

Well, bought some off ebay about £3 posted next day :D
Put it on last night along with my new wheel spacers and ive got to say it has made a difference! Feels alot smoother from cold and at low revs, and also feels like it pulls a bit harder :cartman:
Also massive reduction in smoke out the back (I have no cat or mufflers) maybe 70% less smoke :D :D :D
Good cheap mod!
