600rpm for 6grams? peece off!

Apparently this here is the best you can use, even Ferrari uses it (again 'apparently').

I had used dielectric grease on my old T4, but the Interwebz doesn't recommend that stuff anymore, instead a 'synthetic grease protection' should be used?!

[Buller_Scott]

wao! that stuff's pretty pricey!

why doesnt the web recommend dialectric silicone grease any more, now favouring "synthetic grease protection"?

or is it just marketing playing around with semantics?

[gecko2k]

I forgot to bookmark the pages, I'll post the link when I have found them again!

But I found this on wikipedia:

Dielectric grease is a nonconductive grease. As such, it does not enhance the flow of electrical current. Thus electrical conductors should not be coated with dielectric grease prior to being mated. Dielectric grease is, however, often applied to electrical connectors, particularly those containing rubber gaskets, as a means of lubricating and sealing rubber portions of the connector.

edit:

Found some again:

I've been now to 2 Supercheaps, 2 Repcos, several car and computer shops and nobody can really help me with the grease. I am tempted to order stabilant22 or some cheap stuff from maplin in the uk, if I won't find anything soon! That's so frustrating!!!!!

Thanks for the tips, tried this however no discernable difference. My car remapped and always has revved to 4500 prior and still does after, but no further increase.

Permatex Dielectric Tune Up Grease is the small tube I found at the local auto pro, if you ask for dielectric people go blank, but "tune up grease" meaning grease for the old style distributors and the like, they then find the right stuff.

I've monitored this at length, and it throws no errors at all on Vag Com, and whilst I still believe it "changed" the turbo response curve for me initially, I can't seem to make it "last". It's as though the grease prevents a contact or two, and the car defaults to some sort of different map, but then the ECU pulls it back into line. I'd have to agree with Stormy that it doesn't seem to have much effect on the MKV - seems it's a 1.9 thing!

Well it could be the dielectric grease you are using Greg. After the the first big wave of cage modders, people started to post that dielectric grease is not the best for the job (as mentioned with a few links in my earlier post) and a few different greases are now the ones 'to be used'

[gldgti]

OK, not a very positive comment but this all sounds like baloney to me. Greg's got it right in that if you do something to cause a failure of the signal from the MAF to the ECU then you will cause the ECU to use a map that does not rely on a MAF reading, which could potentially provide the change in engine behavior that people are reporting.

Greg's big reporting post after he did the mod sounds a lot like the car has defaulted to a maf-less map (for a time at least).

Beyond that, its possible that the dirty contacts you create by smearing grease that is less conductive than the electrical wiring in the vehicle modifies the signal from the MAF enough to give the ECU false information - kind of like the "resistor type" tuning boxes that everyone bags out.

Last time I looked at the connector of my MAF sensor, it looks brand new like it came from the factory... I say leave it that way. If you happen to drive on salted roads and have some issue with large amounts of dust or mud in the engine bay, ok clean it out and put some nice rubber grease on the o-ring in the connector - otherwise your wasting you time.

[Buller_Scott]

i did it on my 1.9 purely based on the things i read on the two tdiclub cage mod threads... otherwise i wouldnt have wasted the money (im not exactly loaded).

i will have to respectfully maintain that it did make a difference for me. at the very least, it's keeping crap out of the connector, but in my case it delivered low-down and upper end driveability that i had not known before.

[gldgti]

but it still does or has it gone back to "normal".

True enough if your connectors were dirty then you may have improved things.

[Greg Roles]

It made a difference to me at first, and it seems Scotty has found it continued, so I'd have to say for the 1.9 it seems to be a great idea, for the MkV etc, not so much. Don't start arguning like the petrol boys now....
