Default Odd Sound

Ok, for the past few days i have noticed an odd sound comming from the front left side of the car. it sounds like a gear grinding to a halt. it only happens after the engine is turned off and then started again(it does not matter if the engine is off for 10 seconds or 10 hours it still happens) the noise occurs within the first few hundred feet of driving and occurs reguardless of wether or not the car is in gear(i.e. killing the engine while driving and then restarting it). any ideas on what the cause is???

I think that may be just your ABS going through it'* self test routine. I've heard of this. Some cars do this. I think Jr knows something about this one.

hmm... i'll have to have my foot on the brake next time i go for a drive to see if it pulses. but it just poped up in the past 3 days or so, so if it is a self test wouldn't it do it all the time??? not just the past 3 days???

Check to see if it always happens at 14 mph.

Check the PMV reservior. Is it getting fluid from the master cylinder? You should see fluid in there. It may be low (but the sensor should catch that?) and might be trying to pressurize the lines. It builds pressure up behind isolation valves for traction control purposes (not ABS), then releases the pressure in spurts to the brake cylinders to control traction.....applied braking. If all seems well here, and your traction control and ABS are working correctly, the pump itself may be going out. This will be a PMV replacent. The pump isn't serviceable by itself. You're talking about 300 bucks, and a messy dirty nasty job. I've done it twice. Don't ask. The good news is that you'll almost entirely flush your brake system by the time you're done bleeding.

Now if this all sounds like doom and gloom, can I ask if you have the Electronic Level control? When you accellerate, the back of the car settles......see where I'm going with this?
