Hey everyone I've been getting the code p1498 and and an on and off eml light for the past month on my r53. From what I've seen this code is usually resolved with a IC boot upgrade or SC inlet tube replacement (I have done both). This started happening after I installed a 17% supercharger pulley. Ive put the car into "front service mode" and I can't find anything wrong (while doing this I managed to accidentally crack my MAP sensor hose, but that has been replaced). I also have noticed this code pops up for people that live in colder areas but i live in Hawaii and the weather is definitely warm here. Any help would be appreciated, thanks.
