Obd Reader/scanner Advice Sought

[Socks]

Hi, am thinking of getting one of those handheld code reader/scanners you see advertised everywhere, for my 2001 2.0 litre petrol C5.

 

Any advice on which one to get? Which protocol (ISO, PWM) etc.? Anything at all, really.

 

Thanks

Update:

 

Bought a U380 hand-held reader from this site - which worked a treat, once I figured out that the erase button doubles as a scroll button depending on what menu level you're on.

 

The device itself detects the protocol (ISO-9141) and displays the fault codes, the definitions of which are listed in the supplied instruction manual. Erasing the codes will clear the MIL (the "Check Engine" light) on next switch-on.

 

Have to say I was pretty impressed the thing actually worked given all the horror stories that surround buying these things off the net.

 

All I have to do now is cure the misfire... :D
