Got a faulty thermostat causing a CEL. Also causing my heater to work intermittently. I found a janky video for a G80, it may be the same but I’d rather ask if there’s any service techs on here that can share the official steps for replacement. I’ve got the thermostat in hand. Thanks in advance!

Had electronic thermostat (P/N 25500-3L100). replaced under warranty twice in my 2017 G90, the second time was last July at 28K. Drove it for a few weeks each time after check engine light went on, sometimes intermittently, and it took several weeks to get part and service appointment scheduled. Never noticed any difference. Dealer said it was a half day job complicated job.
