OBD I vs OBD II
Sorry if this has been discussed before, but I'm very curious about the differences between OBD I and OBD II cars. Which Mercedes model years started using OBD II? Is there a difference from a tuning perspective between the two standards?
Thanks. |

I'm going to keep this as short as I can.
OBD II was mandated & implemented by 1996. Some mfg.'s started a little sooner. The purpose of OBD II was, to establish somewhat of a standard for all vehicle mfg.'s. Also, OBD II is much more sophisticated than OBD I, the idea is to minimize exhaust emissions even more than before. From a tuning perspective, it is very difficult to " fool " OBD II. Even some minor changes/faults can trigger the Check Engine Light ( loose gasoline filler cap, etc. ). Hope this is what you are looking for.
