I got mine repaired at the sho
I got mine repaired at the shop as I am not much of a mechanic except for basic tune-ups and oil changes, but the replacement looks pretty simple. If you are somewhat of a mechanic, I think you can do it yourself, but you may need to reset the computer. If you lift up the engine cover, you will see 2 red actuators on each side of the engine. (They actually look like red round circular covers on top of where the shock absorbers would be.) I paid around US$2300 (parts and labour) for the repair in Hong Kong. The parts are quite expensive here, but much cheaper in the US. (Try Parts Source.) I haven't had a problem since then. Good luck.
