My 2008 XC70 just hit 99,000 miles and I’m now getting the exclamation point light and a “make time for service” message. What is needing service and how do I reset the indicator/message to where it doesn’t come up?

I am getting an accumulation of rainwater in the rear hatch taillights. I have not removed them or disturbed them in any other way. If anyone has any experience with this, any information would be much appreciated.

I had made a mistake, it was only those two codes.

What I meant is it runs smooth, no ticking. Your responses have be immensely helpful and I thank you!

Not to my knowledge. I bought it used at 85,000; it now has 97,500.

It runs like a sewing machine. Any suggestions on where to start? I also have seen an aftermarket spacer for the rear O2 sensor mount on the catalytic converter. It’s supposed to create some distance between the sensor and the exhaust, tricking the ECM. Any validity in this?

P0420 & P0430
Catalyst system efficiency below threshold; bank1 & bank2

I was told there are 3 catalytic converters. 1 in the manifold and the 2 in the exhaust. Is there anyway to figure out which one(s) it is?

When you say air leaks; you mean from the intake? Exhaust leaks?

My engine light has come on and is presenting 4 codes; all for the catalytic converter. Can I remove the converter, patch the exhaust and be able to reset the warning light?
