Having just gotten my hands on an OBD-II Scanner :) I'm finding the Ka's diagnostics port extremely stiff... Presumably this is quite normal? There doesn't seem to be a catch, I merely have to give it a big tug...

Cool, where did you get it? Is it a laptop/PDA version or is it hardware? Does it have a dashboard on it? Etc.

The OBDII gives you the potential to record, in real time, all sorts of engine and powertrain sensor values and positions and graph things to see what the effects are when changing things.
E.g. before and after pictures while cleaning the MAF to compare the readings from the device. It's pretty obvious the MAF was reading 0.06 - 0.7 pounds per minute high before cleaning on tickover / normal revs, also pretty obvious the MAF reads higher at higher revs, following the graphs, pointing out that the MAF is working but overreading due to gunk until cleaned:

Fair enough, you could not know whether it was reading high or indeed varying with actual airflow. You could just spend 100 notes on a new one and see if things changed. You can also drive the car with various things being logged until you recreate the problem you are trying to diagnose. Then, you can see which sensors are reading what at that moment, which probably tells you what's going wrong.
Not an expensive tool. ISTR paying about 90 bucks, hardware and software.

Heh, thought about that one, but you need a bit of hardware too :o(
Is that standard diagnostic stuff for all cars? Or do diffent makes use different connections/software? I was thinking of getting the relevant cables and software for my Polo (Sept 01), just out of curiosity really.
I get the impression that they don't all use the same interface, though. Ford use pulse width modulated, PWM, while Vauxhall use sommat else, for instance. It may well be the socket is the same shape / pins.
