Yeah the signal needs to be constant, the chunk missing is sending a signal the ECU can't read so flags the fault.
Looks like you need a new wheel hub as I'm not 100% sure if the signal ring is just pressed on or not.
Think you're right Lee. I know you can get removeable ones for the rear, but on the front the abs ring is actually part of the hub
Oh great. I can't really afford it atm!
Well at least I've found out something which wasn't answered. Today I plugged the abs sensor back in just to test it out, and guess what, the power came back! I knew it wasn't my imagination or me getting used to the power, the difference was night and day. I could hear the Forge 007p even with the standard airbox back on!
So to anyone who may read this, without the abs working the car DOES run in some sort of protective mode.
