Where to start
 

Hi all,
quite an issue with the wife’s 08 cooper.
the symptoms are:
Loss of power, clicking under bonnet, smoke out the exhaust, misfiring. It’s intermittent but seems to be getting worse now. It all started when we put super unleaded in the car at last fuel up. Started the car (at the fuel pump) engine light pinged up straight away. The car did drive fine home, but since then has started all the symptoms listed.
I’ve plugged it into my cheap obd reader and got the following codes:
po365… camshaft sensor
po1105, p111b,
would bad fuel cause this and I’m guessing it’s done some damage to a sensor? I’m at a loss as what to do next.
cheers
Jay.
