Hi all in my endeavours to sort out my 09 Fiat 500 Diesel, I bought an Autel MS300 Scan Tool / Diagnostic to read and clear fault codes. It cycles through the different OBD2 protocols and then comes up with "Link Error". Does anyone know if Fiat have a specific protocol (as VW do) that requires a specific reader? The reader works perfectly on my other cars (Ford Mini Mazda) cheers
