When one of the wheel bearings on my 2002 S80, with 160K miles was starting to fail 2 years ago, I decided to replace all 4, and also all 4 on my 2001 C70, as that had also passed 160K miles. As it turns out (pun intended), all 4 appeared to be in great shape still. But I felt good about having don...

As our P80 cars are around 30 years old now, what preventive maintenance are you doing to ensure they keep going? Apart from the regular fluid changes (coolant, oil etc), what are you keeping your eyes on? In the past year, I've replaced all my coolant hoses, turbo pressure hoses, lower and upper en...

Just wanted to close this thread off by saying thank you to everyone who contributed on it and for the great advice/troubleshooting tips. Unfortunately the day I dreaded my transmission would some day go has arrived. I guess at almost 230k miles and being 28 years old, it's done well. I'm having the...

m Having seen all the work you did on the PnP switch, if you are still getting slips or rough changes in gears it may unfortunately be a bad transmission. Do you have AWD or FWD in your car? The V70R only came in AWD in North America as far as I know, but I believe it had a FWD version in Europe. I...

When you say drained and filled, do you mean you just pulled the drain plug and refilled with 3.5 liters each time or you did a flush? Did you use the correct ATF? When you show that dipstick picture above, was that with the engine and trans oil hot? Neil. Hi Neil, I drained and refilled with 3.5 l...

Did a quick skim of the info in this post, but did not pick up anywhere if the trans fluid level was checked or if/when the trans oil was last changed? Apologies if I missed it and it is there. Neil. Hi Neil, the ATF fluid was changed twice back in Sept 2025 with Dexron III. I checked the fluid tod...

Hi aeg or anyone else. Following on from my last post and after realigning the PNP switch where I get reverse lights ok, it's starting in Park and Neutral fine and no up arrow and check engine light on, I went for a test drive. I was still losing gears when I stopped or slowed down. Managed to get t...

Hi aeg, I opened up the PNP switch again and did the rebuild by stretching the three springs a lot more this time. I put it all back together and the up arrow and check engine light has gone out!!! I cleared the DTC codes and no longer have any transmissiin errors. When I re-opened the switch, I not...

Yes, that's right. If you look at the chart in the lower-left corner of the wiring diagram, "A" is A3, "B" is A4, "C" is A5, "PA" is A6. Where there is an X in the chart, you want to see less than 10 ohms. If there is no X, then you want to see high resistanc...

Just to make sure I have this right, I'm looking down into the ECU and TCU housing and I hook up my multimeter like so and test continuity on pins A3 (jn P, R,N, D, 3, L), A4 (jn P, R,N, D, 3, L), A5 (jn P, R,N, D, 3, L) and A6 (jn P, R,N, D, 3, L)? Yes, that's right. If you look at the chart in th...
