Very interesting. More interesting to note the incomplete drain hole. That would seem to be a problem... Thanks for sharing!

Explore around a little. If you go into each one, it will tell you when it occurred, how frequently it occurred, and how many normal cycles since it occurred. If it hasn't been read and cleared in a while, these may be old. (Perhaps when the battery went flat 2 years ago, or whatever happened to you...

If you are in a position to remove one of the wheels, you can often read the part number from the current rotor. Sometimes it's obscured by rust, depending upon where you live and drive. That can also take a bit of detective work if it's not a Volvo rotor, as you have to figure out who the manufactu...

Also, when the fan is not running, if I turn the manual knob, I see the green light for the A/C turn amber when the fan knob is at zero, then green when the fan is supposed to be turning. I have not been successful in inducing airflow by driving with the windows cracked open, so I don't even get any...

What do you mean by ignored controller ? By that I mean I can set the manual fan control somewhere (middle, max, off, anywhere in between) and the LED's around the knob light up in the corresponding position (middle, max, off, in-between), but the fan does not change at all. When the fan chooses to...

I'm having trouble with the climate fan in my 2002 V70. It's intermittent. Sometimes it blows in pulses. wooh, wooh, wooh, maybe about 1-2 Hz. When the car is really hot, when it's been parked outside and baked in the sun, (interior well over 100F,) then it doesn't blow at all. (Most inconvenient, t...

I agree with SuperHerman - you need to figure out what's really going on first. It's pretty common for people to be sloppy filling oil, and/or a hard oil fill gasket, allowing oil to leak out, and it finds it's way into the spark plug holes. Is the oil more centered on the middle cylinders? I'd clea...

I agree. 0 fuel pressure measured at the rail points to a fuel pump issue, and the question is: is the pump not running, or is there an obstruction that prevents the fuel from flowing. ViDA will indicate what the CEM *thinks* the PEM is doing. See if you can find the fuel pump. If the pump is runnin...

Does anyone know if it is possible for a mechanic to inspect to see if the drain hole is there without having to disassemble the entire engine to look at it? If it is plugged up, maybe clean it out somehow? I'm so nervous this thing is going to fail. Maybe. Yes if the manifold is coming off for ano...

Man, I wish I had seen this prior to purchasing my v8 2005 with 59k miles in July 2019. I do love the XC90 and hope engine 7001 doesn’t suffer this defect. Here’s to hoping. Great write up, at least I know if I hear an engine noise, get it towed immediately Cducasse, Don't regret it. It sounds like...
