Hi all, have broken down 11 miles from home today. CHECK HYBRID SYSTEM, TRACTION CONTROL LIGHT, CHECK VSC, CHECK ECB. Called AA he came and run diagnostic code appear to be 0340. Took camshaft out and it is chipped! Car starts but but shuts after 3-4sec and doesn't sound smooth. Can this be chain tensioner? Any other ideas or can someone share contacts with a decent mechanic who would. Should I first try buyng new sensor? I'm based in Eastbourne East Sussex, but willing to get recovery for the right garage. Please help, thank you
