Recently cleaned my DISA, ICV and replaced lower boot. Completed Vanos seals, spark plugs, and gaskets.
About 100 miles later SES light comes on. Checked it and these codes popped up:
P2240, p0171, p0174
I know the p2240 is an o2 sensor related, but not sure if that caused the other two codes to pop up too? Going to recheck the intake boot and make sure its on tight.
