I lowered the car and that was all fine , eventually got round to havin the camber and trackin sorted , since the car has been tracked and sorted there is a weird knockin noise when the wheel is turned , does any one have any ideas , also the engine light has come on and i no that it is not related to the knockin noise , but the fault code comes up as over boost , wud a faulty waste gate or any other bits on the turbo cause this problem .
