2.0 T S 16v series 1 in 916s Spider
To sort out this UK 1995/6 engine, I need to read the OBD 3 pin. I have cabled up to an ELM437 but nowhere can I find software, hardware or the protocol to give readings successfully. The engine has failed MOT on very irregular high emissions, has a lumpy idle when cold with timing issues thrown in, all after some 5 years standing idle.
Know of a suitable OBD reader or have you had the same troubles? Can anyone assist, please?
