Citreon Berlingo 2007 ?

We are working on a Citreon Berlingo 2007 and our diagnostic informs us that the problem is the crankshaft position sensor is at fault but we cannot find the location. We did phone main dealer for advice and they said it was in the engine (great help) Could you possibly email a picutre. Many thanks Lyn Russell on behalf of Bracknell Service Centre
