My Ride: 2004 325XI
Peake codes 19 E3 E4

I got codes 19 E3 E4 for 2004 325xi from my Peake Research R5/FCX-3.

Table 19
E3 is O2 sensor adaptation limit Cyl # 1-3
E4 is O2 sensor adaptation limit Cyl # 4-6

and was going to replace O2 sensors, but saw threads concerning DISA. I used the two youtube videos below to find the DISA and confirm its bad.

This place is awesome!
