ECU identification

Good morning I have a diesel ECU DDE NNN 500340 will any of the other numbers on it tell me if it is OBD compliant,and how much horsepower it is rated at ? thankyou

Generally speaking if your car is a CDT then it is 115hp and if it's a CDTi then it will be 130. However either can be mapped to 160 by several of the T4 operators on here.
It does seem to be more of a lottery which will talk to other devices through the OBD port as my reader works just fine on my 2000 CDT but won't connect to my friends 2003 CDTi ??

I'm sure someone with more knowledge will be along shortly though

As I recall, the NNN100692 was OBD compatibel and the NNN500340 isn't.

Is it luck of the draw which you have or is it later ones are compatible ?

Later ones are generally compliant as they all use the NNN500340, If the check engine light comes on and goes out once the engine is started then it has 500340.
