you're absolutely right, I remembered that bit incorrectly, apologies!

IIRC I had the same issue with level but it burped itself over time and a few days later the level was right (obviously bearing in mind is affected by temperature)

Thanks GeorgeandKira, Watched on uTube to put heater on max (check heat coming through) and blower on minimum, warm it up. I ran 5 mins warm up, drove 3 miles. May drive further tomorrow after I try the heater thing. I'll take expansion cap off and back on first.

Seems my o2 sensors are ok. I recently required a cat for the MOT, as some kind previous owner had relieved me of the complete innards of mine and welded a patch back on the top. The Volvo specialist garage who repaired it said the sensors were fine. Have a wild guess if I was amused?
