Hello, I'm Brandon - BMW tech.
If you have the code I could help you pin point the problem.
Do you have a Laser Temp-Gun to pinpoint the converter?

Customer reply replied 3 years ago
No my son has the car. The guy erased it and the light temporarily went off after about 40 miles it came back on
Customer reply replied 3 years ago
I can get a temp gun. What should I look for when I shoot the temp on the converter?
BMW Mechanic: internal88, BMW Mechanic replied 3 years ago
I need you to aim the gun at the pipe before and after converter. Record the temperature.
If the temperature is the same then you have converter problem.
If you can get the code , it will very helpful.

Make sure you warm up the car first before checking the temperature.
