Silicon Dielectric Grease - Smoother running, more responsive & less smokey TDI!!
- Thread starter EdButler
- Start date
Clean/deoxidise the connector terminals for an improvement in maf function. Apply silicone grease to prevent further corrosion.
I used KENT S100 silicone grease on the MAF,MAP and N75 connectors and it did make a noticeable difference,the engine is definitely running smoother
.I would recommend it for any diesel engine,anything that makes a diesel vibrate less is welcome

If I ask very nicely, is there anyone here who's local to me, or willing to post me a dab of this dielectric grease? PLEEEAAASE
Sorry to reserect an old Thread but do you guys still carry out the use of Dielectric Grease on the MAF connector ? What about newer vehicles is this still a good procedure ? (they seem to have a more secure connector than on the older TDI's I used to have)

I applied this today, and initially thought it seemed a little more responsive at low revs, however having done 20-30 mile drive I am suffering with a lot of turbo lag to the point it drops off boost on bends etc. My maf was spotless anyway without this but can the grease really cause that problem?
Also my car has been sat for over an hour after my drive which was leisurely but progressive and the engine is still at 90 degrees, its so hot I burnt my hand on the tandem pump. Any ideas??
By the way my turbo is only about 3 weeks old and has been fine until today.
For info I have also unplugged my injector harness and battery today due to non starting issues recently but its all back on fine noww

Seems to be this stuff is intended to keep water and oxygen out of electrical connections but not to actually enhance the connection itself, as the grease is electrically insulating - there's an article about halfway down this page:

I've just bought some Dow Corning DC4 but I'm thinking actually using it on my MAF/MAP connectors might be a bad idea, if the signals are low-voltage...

It surprised me that it had a bad effect when there are so many people that have seen an improvement. My mpg even dropped from 41ish to 38.
Today I've tried to clean it back out with a tooth pick, and ended up spraying some specialist quick drying contact cleaner (made by wd40) in the male side of the connector. Also took the MAF off and cleaned it with the same. Wow what a difference, the restored performance had me smiling and mpg went back up to 43, even saw an average of 44 at one point and I've not seen that ever. Have the MAF off first and clean it you might feel the grease isn't necessary

So let me get this right, yiu have a TDi and it had a hesitation when not hot?. Mine has but is fine when proper hot, quite a noticable hesitation. I will give this a try. cheers
