I tried running an aftermarket intake but kept getting lean faults. I went back to stock but I removed the extra air filter they added for the N26. The lean fault returns but it takes much longer than with the aftermarket intake installed. I also have a BMS stage 1 tune and am hoping that isn't what's causing the fault.
