Shockingly I passed Maryland emissions during covid with a vrsf catless downpipe on a bm3 stage 2 e30 ots. Tried that again in October but I failed. Emissions retest is free so I thought I'd try out the stock map hex code method. I put back on the stock intake as well just in case. Still failed due to P00BD: Mass or Volume Air Flow A Circuit Range/Performance - Air Flow Too high.
Tests cost $10 so I would rather try and pass before removing mods. It must be the er charge pipe or vrsf intercooler throwing the code. My plan for the 2nd retest is to add P00BD or its hex equivalent to the block list and try again. Does anyone know if adding P00BD to the block list will work to block the code or do I need to convert it to a specific hex code? |
