Check engine light after installation of air intake
Hi all
I have a facelifted W205 C63S, and lately have installed a Blackboost air intake for the M177 engine(https://www.blackboostusa.com/produc...-intake-system).
However, post installation, the car is throwing a check engine light with the following trouble codes(scanned from OBD2 reader):
P237528
P237700
P012B28
Upon seeing the CEL, I removed and reinstalled the intake completely, making sure that the coupling boot with the turbos were sealed and MAP sensors properly inserted, however, the car continued to display the CEL.
Blackboost also provided a pair of alternate extension cables for the MAP sensors that have the middle pin removed, which they say can remove the CEL if they are used in combination with plugs that seal the holes for the MAP sensors on the intake pipes, and instead plugging the MAP sensors into the airboxes instead. The red circles below indicate the holes which the MAP sensors should be inserted into, in this case they are plugged.
Trying this threw a new code, P012D00.
The manufacturer also mentioned that the CEL may also be caused by factory ECU settings on cars sold in certain markets that have emissions restrictions. I live in Japan, so not sure if this affects it.
Any suggestions for what I maybe able to try to fix the above? Also would it be safe to drive the car in either state(it did not seem to enter limp mode during the initial test drive)?
