well lads, engine management light came on yesterday in my 2006 blob eye sti- irish car- no effect on car, running flawlessly as usual,
done diagnostic today- code p0420 showed up reading "Catalyst system low efficiency"- the fault also read as "historical"- code erased and light has stayed off.
ok, i presume its referring to sportscat in down pipe-?
last november i had stage 1 power upgrade done- second hand prodrive sports cat downpipe fitted- de cat mid section and hks cat back system- it was then re mapped.
my question is:
1.do i need to do anything else if light stays off as i presume its old fault code reappearing as a result of exhaust system fitted last year.?
2.if light comes back on does it mean new cat?
any idea's welcomed and appreciated, thanks
