2019XC90 O2 BANK 1 SENSOR 1 ERROR Help
Hi All,
my 2019XC90 D5 had the O2 BANK 1 SENSOR 1 ERROR 5 months ago. Dealer said it was a faulty upstream sensor and replaced it with a brand new one
I only drove a few K in the 5 months and now the same error came back, it shows o2 slow response Rich to Lean. I also noted acceleration would feel randomly jumpy and laggy, when i push the gas a bit hard say close to 2000 RPM , i can hear hissing sound coming from the left side. Explained all that to the dealer but they didn't do any smoke test and still said it was the o2 sensor.
Does anyone experience similar Issue and can offer some help please
Many thanks
