Eurospec 97 LHD 550 cannot find ODB II port

On my 97 Eurospec LHD 550, we have searched for the ODB II port and have failed to find one. There is nothing in the steering wheel area and nothing in the fuse box area and we have found nothing under the bonnet (hood). On the assumption that we are not blind, it would appear that there is no port. We have also failed to find anything that looks like it would allow a diagnostics hook up. Does anyone know if there was ever a retrofit on this in Europe as there was in the USA? It leads to the question of how do the Ferrari dealers plug in the diagnostic equipment on these cars? Any thought or help would be appreciated.

Mandatory on US cars on 1 January 1996, but way later in Europe.

Bernard, Terry, thanks for the confirmation, but how do the dealers read the error codes. I have the dreaded bogus "Slow Down" light problem. It only occurs after a "hot soak" i.e. driving and then leaving the car stopped/parked for anythng from 15 minutes to two hours. For the moment it has not shut the engine down, but it is getting more frequent. I've convinced myself it is the two ECUs, which are litterally cooked by the underbonnet temperature. I'm about to change the thermocouples and the two ECUs but I was hoping to read the error codes before doing this, rather than doing it on blind faith (in what has been posted by the gurus on this site). I would also like to be able to read error codes for the future.

We don't even use the OBD port for anything but Motronic on the cars equipped with them.

We use the ALDL plugs for the specific systems. Even Motronic is easier/better that way. On a 550 the OBD port was a waste of electrical parts.



You won't find any useful information for your slow down light that way anyway. Also if you had error codes you would probably have a CEL.

Slow down is for exhaust overheat. Lots of better ways to diagnose.

Your point is?


Any of those are likely to be the last tools I would use to diagnose and repair a slow down light.

Brian,
Many thanks, I won't waste any more time on that particular blind alley (OBD port).
