It was just the battery (I think) :lol: tested it with a multimeter to find it indeed had low charge of just 4.8v. Charged it fully which made the warning lights go away and it was able to start. I left it over night and it had a hard start in the morning and it again tested low voltage. Alternator ...

Thanks for this post, it sounds eerily familiar to what I am experiencing today. XC90 v8 was running beautifully yesterday (Sunday) after an oil change and adding some transmission fluid on Saturday. Maybe related, my wife cleaned the car out in the evening yesterday, including shifting the seats ...

Oh just saw Roger's post too. I guess its settled. Makes sense bc the car has been running relatively fine. Thanks lads.

Thanks for the pic. So if I'm seeing that correctly, yours is floating in space, not connected to anything too?

There is what appears to be a spring loaded valve on the end, and it comes from down near the transmission area so that lends to the idea its a trans breather hose.

Investigating an occasional gas smell in the cabin and minor sluggishness. Noticed a hose that's not connected to anything :shock:

I see another similar hose beneath the starter but can't tell where its coming or going to without disassembly.

What hose is this and where is it supposed to connect ...

Completed this job, and feel pretty good about the results. Overall took only about 6 hours of actual work (most of it fumbling around on dis/reassembly in the tight/awkward workspace of the belt area), completed in shorter stints as I waited for parts - got the pro parts sweden pulleys and belt ...

2006 XC90 V8 with a meager 120k miles. My idler pulley seized too.

Hoped I could get away with just a new pulley(s) and belt. I attempted to disassemble, but the bolt wouldn't come out after unthreaded. Moved the pulley aside to see the boss was shredded and ...

for anyone that happens to see this thread circa 2022:

That worked! Hero! Thanks.

Oddly, I'm still not able to manually tune to every station, but always to a frequency within 0.1 which is good enough to pick up the desired station (i.e. I wanted 107.0, it wouldn't land on 107.0 exactly, but 107.1 was sufficient).

This seems ridiculous, but I can't figure out how to tune the radio to a particular station. The left and right arrow buttons seek/scan to only stations with strong signals. For example, say I want to go to 107.0, but by pressing arrows it goes from 106.7 to 107.5 with nothing in between. If I want ...
