Hi My vehicle does not start sometimes and i have taken it in to some centres who ran a test and came up with camshaft positioning sensor error as the engine light was on.They were however not sure and advised i book it in for more checks but given i took it in twice and same result came i suspect it has something to do with the campshaft positioning sensor.I however need someone to redo the diagnostics and look at the faultly part needing replacement as it now fails to start even though the lights can go on the stereo and fan working still.
