2000 Volvo V40 Question: Check engine light--code indicates, catalyst system right bank underperformance?
The check engine light comes on and off about every 5 to 7 days. During the week I only drive 14 mi a day. When I drive on weekend @ interstate speeds, check engine light will go off. When I run the code--it says--catalyst system, right bank, underperformance. What is this? and a estimate of repair would be helpful? car has 185000 miles on it. it gets regular maitenence. - 00volvo40
WITH THIS MILEAGE I WOULD SUSPECT THE CATALYTIC CONVERTER IS DONE. CALL AROUND TO LOCAL MUFFLER SHOPS FOR EST AND AVAILIBILTY. YOU MAY HAVE TO PURCHASE FROM THE DEALER. BIG $ - globalhelper
