This small box (about half the size of a cigarette packet) enables a clever piece of software to connect to your car and detect any malfunctions. Engie connects to your car via the OBD (on-board diagnostics) port, meaning it won’t be applicable to your classics from the 1950s-1980s – but many cars from the Nineties do have these ports. Check online to see if your car has one and, more importantly, where it is.
On our test cars (a 2004 Renault Clio 182 and 1996 Mazda MX-5) connection took less than five minutes and the reading time was virtually instant. It will show you malfunctions in any engine parts connected to the car’s brain, show you your battery charge and enables clever things like fuel tracking.
Some of the software seems a bit overkill, but if your dashboard displays a warning light and you want to figure out what’s wrong without taking it to a mechanic, this is a very quick and cheap way of doing it.
