OK. A quick flick around the forum suggests this is £90 + VAT main dealer. Some suggest that anybody other than a main dealer won't be able to get all the codes off. Others suggest buying a machine.
Would this £20 one do the trick? http://www.carparts-sale.com/u480-can-bus-obdii-obd2-eobd-trouble-code-reader-scanne-p-75.html?zenid=5v2385aoaia5o9cm33khbspuu1
(And others suggest using an Android phone and b/t but I haven't got an Android phone - though I do have a laptop - any other similar programmes?)
And once I've got this info is it going to be much use to me?
Thanks
