Hi,Ive had Fiatecuscan for a while and ive used a k line cable on my 147. I now have a diesel. I was given a "suspect" elm cable but it wont show up engine faults on my diesel but it does appear to connect, the same "suspect" cable would not connect for proxy realignement on my 147 twinspark. Ive read that Diesels were not obd11 compliant till 04. My question is should i buy another elm cable and should it connect to an 03 156 jtd. Anyone here know the best/cheapest source for a cable cheers.
