A vehicle controller receives images from a camera upon arrival 402 and upon departure 404. The departure image is compared to an arrival image captured closest to the same location. A residual image 410 based on a difference between the arrival and departure images is evaluated for anomalies 412. Attributes of the anomaly (for example texture 416 or colour) are identified and the controller determines if an anomaly indicates a fluid leak 420 (e.g. engine oil). Image stabilisation 406, 408 may be carried out on the images. A location of the vehicle may be tracked using GPS and movement information and images captured by the camera may be tagged with a location. An alert may be generated in response to the indication of a leak 422.
