i found two resistors behind my battery on my 2.3 190e.

Both were tapped up and had the following numbers on them. are either of them the r16?

5381

2681

I have a 190E 2.3, but european (1992). Mine has a dial similar to the "S"/"N" near the ignition ECU, but marked with numbers from 1 to 7. Must be the same. But I don't know what the other is. Have you measured its value?

Best regards.
