Gidday,

I have a 2000 V70R, 130000KM, it runs well, pretty fast for a comfy safe looking wagon, but its been bugging me a lot this engine light. It was like that when I purchased it, the dealer who I took the car to said ignore it, he knew it was not serious and said ignore it.

But I still would like it fixed, and got a fright when I was quoted 2 new sensors @ $1500NZ !!!!! and if it was not that then they said $3000 for the CAT. I'm not too sure if their diags are great, they rely on computer codes, but to get through 2 x 02 sensors and still not be sure then I'm worried. Can you test the sensors or somehow proove it?

Their report states o2 sensor faults, but being a computer engineer I only trust computers so far, the old story bullshit in = bullshit out. So the computer believes everything its told right!

I see a lot of suggestions about vacuum hoses, so will go hunting for that, any other ideas/help appreciated folks.

cheers
