Just to update: Our mechanic was able to replace the Volvo 3515641 transmission speed sensor in our 1997 Volvo S90 with Toyota part 89413-32010. Everything works so far. The warning light went away.

The car drove abour ~1600km now after the first drain and refill and we did the second round. After the second drain, the fluid was still rather dark: Bild_2025-06-01_220648181.png Bild_2025-06-01_220703688.png Bild_2025-06-01_220733658.png The gearbox ended up to be overfilled because I added 4L wh...

Strut bearing would be my bet. Great photo on alignment procedure. Fcp euro has a detailed video on similar job but on xc60 in case you need reference. Sorry for your time. Hope it will reward you with another 190k of noise free miles. P.S. extra respect for a nice coat of fluid film Hey , thanks f...

The most comfortable setup on these cars that I've experienced is Bilstein B4 shocks/struts and H&R 29955 lowering springs. Rides better than stock, looks great, and handles fantastically. By far the best setup for P80.

Problem was small bits of corrosion on the CEM circuit board. Cleaned, reinstalled, car started right up.

That doesn't matter....the battery shows voltage of 11.9v.That is flat battery.
Full battery must read 12.7-12.8v.
12.2v is 50% charge.

After many years away, I'm back to Volvo and just bought one of these. '18 S90 T8, Inscription, black with amber interior.
Fingers crossed the S90/V90 forums will be as helpful as the 850 and V70 sections have been in years (and cars) past.

Ok. This may be resolved. After buying replacement driver side cv axles I finally no longer have any clunk after I ordered a used axle with the anti vibration piece attached. I bought an aftermarket at first and it flunked and then I bought gkn new and it flunked but no longer getting a clunk when r...

Thanks for replies guys. Of course this started happening right after I filled a tank. Happened twice more today. I'm noticing it happens when you start the vehicle warm, like after being stopped after a drive. Had a weird throttle flare happen too. I'll be cleaning the throttle body and doing an ad...

Ok, so it's buttoned up and running. No check engine light. Had a few bulbs go out, so I replaced those. Will post pics of the bulb numbers from the parts catalog for everyone's reference. Now have to get EVAP. O2S. and CAT code to reset. Usually when I take a long drive on the highway, out to my fr...
