Hi everyone, I've been looking through eBay for the last half an hour or so, and done a few searches on here, but couldn't find anything and don't really know what I need. I want a reader to scan my car with, but the prices vary so much. Is a £5 one any good? Or are they best avoided? I've seen this one: VW AUDI SEAT SKODA VAG Fault Code Tool Reader Scanner OBD1 OBD2 CAN COM | eBay And this one: VW Volkswagen Golf polo Passat Fault Code Reader Scanner diagnostic scan tool | eBay But like I've said, I haven't a clue what I'm looking for. If someone could suggest one with a link, I'd be forever grateful. Cheers, Callum.
