ok here's a wierd gremlin

[s2driveruk]

Thought i'd take the car out last night as the carpet was out along with the interior to see what difference it made to the car (quite significant actually ) and what i thought was a cluth wearing/noisy thrust bearing seems to actually be a wierd electrical noise coming from under the drivers side dash.

Under load it seems to make a loud crackly kind of hum and then off throttle is sounds like a sort of electrical version of a scraping/clutch wear noise. I'm 99% certain its not clutch but absolutely no idea what lives under the dash (maybe on the relay plate/secondary fuse board) which would be sentitive to throttle position and could make this noise. when on low throttle the sounds goes away but floor it and its really noisy!

Any likely candidates? i'm baffled

I did have a quick check that nothing was hanging out the fuse plate - i wonder if there is a poor connection or short somewhere.

Cheers

maybe one of the vaccum hoses leaking? it does become apparent if you take the carpet/ noise dampenings out.

i have my ECU hanging out now and you can hear clicking from time to time

Wierd. As per A80, check thine vacuum lines and also groundeth thine ECU well my son.

i'll get my head under the dash and see if its anything obvious but its definately a strange noise for sure

not while flooring it I hope... could be a rather comprimising position if you get someone to help out as well... "officer, she had her head in my lap while i was pumping on and off the throttle so she could hear my relay"...

Sound as sensible as hawking the boost gauge on a 3rd gear run...

Thats not going to happen...Davids married with children all that nasty dirty business finishes after child number one didnt you know that Ross

[s2driveruk]

oh how true....

Now, whats causing this bloody problem under my dash

[s2driveruk]

bump.....

any ideas?

[s2driveruk]

ok, this is really starting to get me down about the car, had half the centre console out and a) i can still here it and b) no closer to solving it.

Anyone else have any other potential pointers on what could cause noises in that area?

[Rusty]

I'm starting to remove the sound deadening to either replace or remove completely. Wonder what I'll start to hear

[s2driveruk]

i am sans deadening felt and you can hear everything Some of it i'm sure is normal, this particular issue i have is not i'm pretty sure

[Acidburn]
