downpipe question

john boxter · 01-14-2010, 01:52 AM

hey ive been doing a lot of research but i was wondering did anybody instal downpipes with the bms o2 sensors and still throw a code?

john boxter · 01-18-2010, 06:43 PM

sorry didnt specify catless downpipes?

I installed the 02 sim after my catless dp install and still threw a code. I eventually bought an obdII scanner and cleared the codes but I think your best bet is to install both at the same time if I recall correctly.

i have catless and BMS 02 simms. I, and everyone else was good until the BMW software update. This is why there is a V3 that just came out today. yes, i bought it, yes, i am selling my BMS V2 02 simm

YOu sure, with procede you able to pass inspection because it gives the ECU a readiness code, and as long as there is no check engine light you should be fine...
