I bought an Autel, Eu702, cost £169, it is a bit cheap and plastic, however it does turn out airbag lights and covers a lot of cars, gives out live data and looks at emissions. I have used it a couple of times on the Z, the wife's mini & my neighbours Skoda & Fiat and it seemed to work well. You can pay a lot more and I am sure there are better ones on the market, but it does what I need it to do so I am pleased with it.
