I bought a 2023 G63 in May and after driving it for about 2 weeks, the check engine light came on with only 700 miles on the car. OBD reader showed code P0304. The car was driving fine, no issues. I took it into the dealer on June 7th and the car is still there. First they said it was an exhaust leak and they had to replace the exhaust system which did not fix the issue. Then they replaced the ignition coils and the issue still wasn't fixed. Now they are going to replace the fuel injectors. Just wanted to see if any other members have had this issue with their G's or any other amg's using this same engine?
