My wifes' 04 V-70 with 68k miles had the check engine light come on this past Friday, at the start of the holiday weekend. I finally get to use my new Actron code reader cp 9180 model. It spits out a pending code of PO420 (catalyst below threshold bank 1). I read it again and it is now a stored code on Sunday. I check with my guy Jim at Vovo Clinic and he says its a cat going bad bring it to the dealer, it is under the 8 yr 80k warranty. Tuesday I call the dealer and get an appt for Wed and upon driving down the cel goes off!!!! The service writer says "oh it is probably just a loose gas cap, but here is a loaner and we'll check it out" Turns out they replace the cat and perform a host of software updates at no charge!!! I haven't heard of a catalytic converter crapping out after 68k miles!!!!But I'm glad it was covered under 8/80 warranty!!! JHW
