    Default Cdti rough running on cold start up

    Hi, recently purchased a 1.9 cdti 120, with 110k miles on the clock full service history with last service done 2 weeks ago. I have noticed that on cold start up the car will start first time but the oil pressure light will stay on for approx 5 secs whilst the engine is running. Whilst the light is on there is blue smoke from the exhaust and the engine sounds rough. Once the light has gone off smoke stops and engine sounds normal.

    No fault lights car drives fine and will idle at the correct revs even when oil light is on.

    This only happens on cold start up and at any other time oil light goes off as soon as car starts.

    No smoke when being driven

    Any ideas?
