I’ve a 2015 M235i. Dinan stage 2 tune, VRSF excessive stream catted downpipe, VRSF cost pipes, VRSF upgraded intercooler, 1 diploma colder NGK spark plugs, and upgraded coils. I’ve a CEL on as a result of downpipe. Are there any choices to get the CEL off to cross emissions, in need of placing the inventory downpipe again on? Thanks prematurely.
One possibility you possibly can strive is to place a 90 diploma O2 sensor spacer in. I did that on my VRSF catless downpipe, on the sensor furthest away from the turbo and it prevented the CEL for probably the most half.
