what year for OBD2

[wolfsbaneracing]

Could someone please answer a 'date' question -
from what model year of R129 is OBD2 relevant ?
I have a '95 SL500 and have been offered an OBD2 code reader / data logger, but I'm not sure if the two are compatable !
Any help or advice would be most useful. Thanks.

I would really hate to steer you wrong, but I thought it was '96.

Why don't you borrow and try it?

The feds imposed it in 1996 but I do believe mercedes started using the obd2 connector under the dash sooner in certain model cars in U.S. only. I have a 96 SL500 and it is the first year of federal mandated obd2 compliance it has both the obd2 connector under the dash ,and the 38 pin connector under the hood on the passenger side in the electronics box.
