I recently installed EGR deletes on my 2015 WRX and got the expected check engine dash light. What I didn't expect was the ABS, hill assist, and vehicle dynamics lights also. And my auto-down driver's window is no longer auto down. Only trouble codes are P1492, P1494, and P1498. All EGR codes. Car drives fine without any new noises, hiccups, stalling, etc. Anyone else have something similar happen?
