Ok, so you are standing in front of a 1998 P38 2.5 DSE looking at the engine bay. Look to the back left and there is what looks a green hand grenade on top of something.
What is it, What does it do and should it buzz and whirr for about 30 seconds when turning the ignition to on?
Recently, when turning the ignition to on I get all sorts of fault warnings coming up. Air bag fault, traction control fault alternator fault and ABS fault along with the corresponding coloured lights. If I turn the key back, remove it from the ignition then put it back in it sometimes goes away. The other day I started the engine anyway, and noticed that when the buzzing and whirring form the afore mention part stopped then the fault light went out.
Im sure it is something to do with the brakes as once I lost all braking and the brake pedal went to the floor!! Luckily I hadn't even moved so locked her up again came back the next day, started it up and the fault had gone. Had it checked anyway and there were no faults recorded (surprised surprise) and the brakes were fine.
Another time, when the part was initially whirring and buzzing and the faults were bleeping and flashing I slowly drove off. Sure enough after about 30 seconds the faults warning and lights disappeared one by one much the same as the yellow and red brake lights go out after about 20 yards!
So can anyone tell me what this part is, what is does, why it whirrs and buzzes and could it be throwing up these other "faults"
Many thanks in advance.
