As it's a bit gloomy out now and I haven't managed to find it yet!

Is there a cubby hole under the headlight switch? If so, pull that right down - In case it copies the fabia

If its in the Ibiza area, it will be under the steering wheel behind a panel which clips out - I think this also is how you accesss the fuses.

Cheers for that. Should do my homework really but thought I'd ask while I'm sat waiting for the scan to finish on mine first.

I think it's under the ash tray (in front of gear knob)

Ah! It is down toward the accelerator pedal, and not even covered by anything!

I must get my eyes tested...

Thanks again

As part of the OBD standard, the diagnostic port should be in arms reach of the driver and should require no tools to access.
