it had no check engine on
and no obd2 errors via bluetooth cheap dongle
that is the problem
so, ECU was modified right?
tech inspection prior owner did in 30 September 2020
CO2 emission idle CO2 % 0.0 of max allowed <0.3
CO2 emission throttle 2000 rpm 0.0 of max allowed <0.2
so just a few months ago it was perfect
bought this lexus through shady resellers 06 Feb 2021
tested same day after 2 hours
CO2 emission idle CO2 % 0.5 of max allowed <0.3
CO2 emission throttle 2000 rpm 0.4 of max allowed <0.2
complete absence of cats therefore
inspector said there are no cats, but no cut outs are visible
shady reseller blames me that I cut out cats on Saturday, at minus 20 C, within 2 hours
what is the cheapest way to pass emissions?
