took it to garage. they found no real faults, cleared fault codes, took it back to have another look and found no faults.
yet it still has trouble starting when engine is run left for 10 to 15 mins and then have trouble starting. the engine turns over starts to fire up and then after 30 seconds of struggling then runs ok. No problems once running. the engine light came on once engine cut out and then trouble starting but this has happened once.
