About once a week now I have to reset the OBD computer. I'm not sure what's causing the problem but I suspect the O2 sensor. I changed the head gasket a few weeks ago but not before plenty of coolant went through the exhaust (silicone contamination).

A local Volvo "expert" tells me that he can scan deeper into the computer and do a more thorough diagnostic and then do a more complete resetting of the computer.

I thought I had all the info through brickboard that I needed to do this myself. Can this guy possibly have access to tools and information that I don't?


>Another question: Can a bad or blocked cooling system throw a code?
