Just got a brand new 2010 Wrx last month. It has 1,700 miles on it now. After driving for 5 minutes tonight, I parked my car for half minute and planed to leave. When I shifted into 1st gear and release the clutch slowly, I heard a big noise came out from the car and it's like grinding. The noise disappeared after ran for about 15 seconds. This happened several times. It seems this will only happen at low speed(also backward) and won't last for more than half minute. Does any have the same problem with me? or does anyone know what causes that problem?
To me it sounds like the hill assist may not be disengaging properly.
Im assuming your mentioning the hill holder system...Is there a way to just turn it off....I didnt think this was possible....Unless you go into the Selectmonitor or something???...Personally I work for Subaru and have never seen a way to disable the hill holder system short of disconnecting the cable on the older models...
The hill assist is controlled by the VDC. I do not think disabling the traction control will completely disable it.
There is a ball...
"The Hill-Holder System operates within the braking system of the vehicle. As you travel on a flat road or a downhill grade, a ball remains at the front of the system’s Pressure Hold Valve, and the valve remains open. When you stop on an uphill grade and depress both the clutch and brake pedals, the ball rolls to the rear of the Pressure Hold Valve, sealing the opening. The closed valve maintains hydraulic braking pressure even after the brake pedal is released."
There are 3 settings to the VDC though. Press once the light should turn yellow, and disable traction and stability control. Press and hold for 2 seconds and it should turn green which is the performance setting, torque reduction is turned off and stability control is lessened.
did you put the ebrake down lol?
Correction - The STI had the performance mode VDC, the rex only has on/off.
Plus just tested it on the drive home, hill holder still works without VDC enabled. Looks like it is mechanical after all.
