Hello all, long time.

I know 2003-2005 XC90's had the GM 4T65E transmission like I rebuilt in my S80, but when did that change? Does any one have a list of tranny / engine combos to share from 2003 - 2015?

Yes, I could probably go spend an hour looking this all up but thought I'd ask.

Idont recall the size, but be very careful, these bolts seem to strip out fairly easily, and at hard enough to get to I the first place. I used a slim 1/4 inch drive with the shortest length Torx bit combo I could find.(253) 582-2408

I would definitely test the coils one at a time, and replace the ones with weak (yellow) or no spark. I'd fix the misfires first, the put in BONE STOCK plugs. None of those $9 iridium super plugs that Kids use in their Hondas with a wing on it. Volvo calls for a specific platinum plug in an S80, and...

If it starts and idles from cold, but won't rev much beyond idle I'd check three things: Unplug the MAF sensor, does it run better? Any shot you have a vacuum leak downstream in / around the intake? Hose it down ( carefully please ) with carb cleaner and see if the engine idle increases when you hit...

Misfires under heavy load are difficult to diagnose unless your engine idles and warms up without error. From dead cold (open loop, before ECU starts reading O2 sensors) how does it run? It the idle degrades once the car warms up, I would do what Matt suggests, check all of your O2 sensors for funct...

Done and done. Ordered a set just now. One for the toolbox, one for the S80, one for the V70, one for the Ford...

Thanks Matt, cool stuff!

Conceptually would the AC run I a dark carport or under shade continuously, or does the sun sensor really detect sunlight and issue a command? I would think there's a way to deactivate hhis behavior in VIDA / DICE.

Can you confirm voltage at the fuse? I didn't know the sunroof was keyed to the BCM, but I guess I'm not surprised. Do you need the VIDA procedure just to check your work?

Interesting idea to use a breathable membrane, do you have a link to a vendor?

I would agree, but only add, you might as well replace the water pump while you are there so you don't have to do the job all over again later.
