So yesterday I took my cruze out to dinner and again I got this B2AAA engine code that I scanned last year, vanished for a couple of months and yesterday it came back.... searched it up some people say its a fake code, others say it a catalyst issue so I was just wondering.... for those with the zzp downpipe ( or BNR ) what code popped on your cruze? My code came on soon as I installed the downpipe but car has always felt strong. note that I plan on tuning the car this year and I know the code will soon be gone
just wanted to hear some input on this.... thanks for your time!
