Today i got the first check engine light on my car and using bimmerlink app i found error 180001 saying Catalytic converter efficiency is below limit value.
I haven't driven my car hard for quite some time, usually city driving up to 3.5k rpm and i was wondering would a hard driving like getting up to rev limiter help catalytic converter to clean? Or should i just buy a new one or is it a God's sign for catless downpipe
