Being a Y3 s1 xm there is no common central obd connector.. Each ecu has its own two pin plug that you connect a diagnostic to .. You then read each ecus faults directly and not globally..

7. The 2.0 turbo engine is slightly twitchy when driving at constant speed and throttle. On wide open throttle it's even worse, really choppy acceleration. It also lights up the Check Engine Light for a short while after giving it some beans. I started by replacing the spark plugs and ignition leads, but they didn't help. What's next? Have also bought a new ignition coil, but have yet to fit it.

Change the fuel filter if you have not already done so. A blocked filter can cause low fuel rail pressure that gets worse as more power is demanded.

Good point, thanks. I just ordered a new fuel filter.
