Mr C commented recently here that he'd never found a computer based one
that was worth having.

92 Astra - Slim

93 218SD - Slimmer

01 Corsa - Fair

Basically, a standard European protocol (EOBD) was only required by the
EU on petrol cars from MY 2001, and oil-burners from 2004. Some petrol
cars before that used the earlier US protocol (OBDII); code readers are
not necessarily compatible with both.

Thanks and I think it was that or something like it that had me all
glazed over last time (too many gotchas and caveats on said older
vehicles to make any purchase a bit of a gamble etc).

Luckily mate has the Suntune jobby and so can generally read anything
that can be read should we actually need it (rather than me just being
interested).

Cheers, T i m

USB cables can be extended if you insert a USB Hub at the 5m point,
then you can use another 5m extension.

I saw a bluetooth obd2 reader on ebay the other day out of china for less than
30 quid delivered. May be a better option. Or just borrow a friends laptop
for the day.
