Ok so I took my R53 out for a bit of a spirited drive last night and it flagged up the ABS traction and tyre pressure lights (It has a 17% pulley Ive heard too much boost can do this?). So when I came to try it this morning, it was still the same. Drove to work, turned it off. Got in it this evening, no lights are on, but going down the road every time I press the brake pedal the ABS is kicking in (at ANY speed) and I can hear what I assume is the pump clicking away, still no lights showing on the dash. Pull over, reset the ecu via the key and speedo button. Turn car back on, lights are on, no ABS locked on.
Any ideas? Ive since reset it again, there is no tyre pressure light, just the ABS and traction lights are still on.
Does this sound like a wheel speed sensor? I just figured it would tun itself out if it was flagged up by too much boost.
