Generic or universal diagnostic tools will work on most cars so long as they meet the OBD2 criteria. OBD2 cars in the UK are petrol from 2001 onwards, and diesel from 2004 onwards. Generally the universal diagnostic tools will communicate with the engine system only, unless otherwise stated. If you want to diagnose the engine fault only we recommend the iCarsoft i800, and if you want to diagnose other systems like ABS or airbags we recommend the iCarsoft CR Plus.
