Small update, got the Leon back today after nearly 2wks in the garage (it wasn't the only thing being worked on) and it was the arb bushes ,all that was needed was some copper grease. Alls good now with the creaking. Also had a full service, SALK and ferodo ds performance pads fitted plus a fast road alignment. The big cost was my helix clutch was fu(ked....again. First time a return spring became dislodged and jammed in the housing..was I unlucky??? Second time the springs in the cover plate are all uneven and wears unevenly eventually causing first, second and reverse to be unable to be engaged. Im no expert in how clutches work but helix have got a lot to answer for. Oh and I have asked them several times with regard to the first issue with the biggest fob offs ive ever had, bloody useless company...anyway the car feels great and cant wait for a bit of dry weather to give it some real beans through the twisties!
