Tool of choice

For this Qashqai, the Snap-on SOLUS Edge diagnostic tool is versatile and comprehensive. It can also be used with many other vehicle makes and models. It is worth noting that these models are known to be easy to use in terms of faultfinding, and that a basic code reader can take you some way through diagnostic checks, including resetting warning lamps, etc. Having said that, many programming operations have to be carried out by specialists with dealer-level equipment.
