Data Link Connector for 1999 E55 AMG




My '99 is a Canadian spec so yours should have the same connector. If your car is a Japanese spec, all bets are off and you will need to locate the Star Diagnosis Assistance System. Much more expensive.
I'm using an Autel MD802 with 38-pin adapter, works great on my car.
