Do your tyres make a humming noise at high speed?

Hi well the normal road noise definatley.....when you say humming noise...is this loud and how fast are we talking ???????

rizzy

100+ gets faster as the car goes faster.

ThrustSSC

It's probably a faulty MAF sensor...









Or it could be a wheel bearing. Have you worked out which corner it is and tried jacking it up and spinning the wheel?

Only if they don't know the words..

rizzy

its not the bearings they are fine.

MAF sensor?

Gutmann pug

you sure your not talking about the noise which comes from the windows seals at that speed? Alot of them seem to do it

Mass Air Flow sensor. Cause of a large number of Scoobies grenading their engines by running lean - if I remember right a model year around MY99 was particularly prone to it. Also a standing joke cause of any problem...

Its probably just your tyres. I'd suggest trying another MY05 STi in similar circumstances. If it does it, too, you've nothing to worry about

ive been using an 03 plate Sti version 8 for a few days.

this one seems to do the same thing starting from around 8o onwards. i'm a motor mechanic by trade and also a bit of a whizz with these car.

To my understanding, i think you'll find that its because its an sti and its got all the active diffs on it. try setting off from a standstill and see if you get the same kind of noise coming from around the rear diff.

I think you'll find its just the computers in the car dispursing the right amount of drive to each wheel.

Dont worry about it kid !

rizzy

Hope it aint MAF does this fault still exsist on current scoobs?

I do get alot of noise from the rear diff but that happend in the wr1. It happens more often in the sti especially on full lock.

Cropsta youe discription match's my problom:so its nothing to worry about?but the my03 dint have dccd.

Thanks for the info guys

I get a drone type noise (doesn't sound like wind) at 80mph but then it goes away as speed increases.I then get a high pitched noise(def wind vibrating something) at 100+.
My dealer doesn't know what the 80mph noise is,although he has suggested its tyre noise.

cropsta

correct mate, it does have dccd, but i dont think it make any difference with one that has and thats not.

rizzy

thanks for your input lads.

05 sti do they have the same brake set up as other models or have they changed the pad design and disc size...........
just wondering if anyone knows as a mate has the 05 and thinks the stanard stuff is awesome but my 03 standard setup was s**t

I think they're the same, though obviously the design of the discs will have to be slightly different to accommodate the wider stud pattern. I certainly have no complaints about mine, which are standard apart from having a set of braided hoses.
