Thanks - so much to consider!!. Yes there would certainly be advantages in having a tool that would give me more specific info (not much point otherwise I guess). BTW I inquired about the Foxwell NT510-530 online. Seem to be some available o/seas (eg. Original Foxwell NT510 Elite Multi-System Scanner) but still looking on Oz . Checking out the Launch stuff now (Scan Tool Archives - Launch Tech Australia). Will update this thread to let people know how I get on.I'll let you in on a wee secret. Workshop service managers don't know a helluva lot about cars. They shuffle paper for a living.
One other thing to be aware of is that OBD2 is a system for dealing with engine emission faults. An generic OBD scan tool will only be able to communicate with the engine ECU. It won't help you with faults on the ABS, SRS (Airbag), or any of the other systems on the car. A Hyundai specific tool should be able to communicate with all systems.
