Can anyone recommend a not too expensive fault code reader that will work on a 2006 Panda diesel? I've always serviced our cars, and have worked a lot on classics, and have rebuilt several classic engines. However, an old f*** like me grappling with modern automotive electronics would be like a chimpanzee trying to do brain surgery. On the 60's and 70's vehicles I was brought up on, the most complex electronic component was an SU fuel pump. But the need for fuel economy and the fact that all the old cars are worn out has forced us to buy a modern one.

I realise that the cheaper a OBD reader is, the less it can do, but can I get something that will identify why an engine fault light has come on so I can at least have an idea of which sensor is sending the ecu an unexpected reading? I don't like the idea of having to take it to a garage every time anything whatsoever goes wrong with it, and paying out an hour's labour charge just for them to diagnose the fault, let alone fix it. Will any generic OBD reader do, or will some not work with certain makes? Can I get somethig that will do this for <30 quid?

Thank you for any advice.
