Yeah sounds like the ABS or brake booster building up vacuum or whatever :-) My MX6 used to do it every time I started the car.

Peter I don't believe I have. The wheels spin freely in the wet if I'm not careful with the accelerator. There isn't a button to turn it off.

ABS works a treat. I did however decide to take a peek under the bonnet for this

and found that I am actually missing the green plug (or otherwise labelled as the TRAC MTR) and obviously the otherside is blank (like most) eg:

So I don't think I have it.

Thank you Hanre.

You inadvertantly helped me out, i had a slight fluid leak that i just noticed and just the other day i noticed a slight noise associated with the steering, Turns out the fluid is low because of the leak and the leak is simply an easy to get to fitting.

Much relief.

I have been reading this thread and trying to isolate why my 95 GT-L does this.

I am convinced it is brake related. When I start it whirrs, but if I touch the brake [in 'P'] it stops.

This thread is also related:

Will check the fuse. What's the consensus on this?

Earl if it's stopped and you pump the brakes a few times does it start again?

I check it and see. Seems to also possibly be related to whether I had the foot on the brake at the time of shut down... will look into that more.

Btw At first I thought it was one of two things:
1] TEMS
2] An internal or hidden auto FM radio antenna [which can;t be so however I have yet to find out where exactly the FM Antenna is - anyone know? Couldn't find that on search]

FM antennae connections are under the back seat i think. Someone more sure will be able to tell you.

IF it sounds like a pump running then it's most likely the ABS pump. I think that my accumulator is low on nitrogen causing the pump to have to run more often. Pumping the brake seems to make it turn on.

Radio antennae is in the rear glass.

Scott, sounds like you are talking about the pump associated with TRC equipped systems.

Non-TRC systems have the ABS mounted near the relay box as you can see in the 2nd pic above and they have a standard vacuum powered master brake cylinder setup.

TRC systems have the electric pump you mentioned with the nitrogen cannister and it is all incorporated with the ABS on to the master cylinder on the drivers side.

This pump will come on whenever the pressure is low in the cannister, eg when first turning ignition on, or when and after braking.

Suggest have a mate in the car to operate the pedal with the car parked and bonnet up, and try to hear where the noise is actually coming from.

The whirring sound is coming from the INSIDE, under the dash I think
