hi, anyone know any of those 30 quid-ish fault code readers on ebay will actualy work on my 04 td5 defender- all I want to do is try and reset the three amigos (well, only 2 of them now- ones disappeared now!). they seem to come up in wet weather.I've read some threads about the subject and it appears some might work but which ones?what obd thingy do I need it to be compatable with?
