What did you do to your P2 Volvo today?

25-40 liters of trans oil for a flush!! Wow. Normally 10-12 liters has been enough for any of my Volvo transmissions.

About June 5 I had a no start condition that final started after giving some throttle. This was on my 2001 V70 T5 with 218,700 miles. I got it home about 4 miles in what must have been limp mode. Poor throttle response. Surging idle. RPM limited to 2000 RPM. I shifted manually to get up to 45 MPH.
I checked codes and had many, including CEM-1A5D Communication with ETM. However, restarts were sometimes good and idle smooth. I checked live data and spark timing, MAF and TPS % all looked OK.
Next day, I restarted and got rough, surging idle that smoothed out after a couple minutes. I restarted and got new codes including ECM-902A Communication module ETM and ECM-903F ETM internal fault. I cleared all codes.
Next day and I started and had rough idle. I checked live data and found TPS (Throttle Position Sensor) was at 0% while RPM was surging around 1000. New Codes were CEM-1A5D Communication with ETM, ECM-904A communication with throttle unit, ECM-903F ETM
internal fault, and misfire codes.
I decided this was consistently pointing to ETM failure although the ETM was replaced in 2019 at 197,000 miles. I ordered the XeModex remanufactured ETM with upgrades. I hoped this was correct because ETM was $643 after core refund of $100.
I installed the reman ETM this week and all is well again. The ETM swap took me about 4 hours. First restart was good with no loose hoses or connections.
I have no complaints about replacing the ETM after about 20,000 miles. I do mostly in town diving so it gets lots of throttle position changes.

Today I got the CEM reboot bug again, car lost all electrical power for a moment and I heard the relays click.

Unfortunately this event somehow decalibrated the DIM, the RPM needle's resting position shifted to 1100rpm even with engine off. How is this possible?

Timing belt, water pump, coolant bottle, accessory belt and tensioner, and a PCV service. I remember doing the timing belt on my '99 V70 in like 1.5 hrs (12 years ago) but this job was much harder. I skinned a lot of knuckles!

I tried to do the PCV without removing the thermostat housing but that was dumb; removing that makes the whole thing easier and I put a replacement on since I had no info on when it was last replaced. I replaced the killer banjo bolt; the replacement from FCP was stamped 2023 which I thought was interesting. The hard plastic line from the banjo bolt to the elbow coming off the oil separator box was so brittle that it immediately snapped. I used some silicon hose I had as a replacement; I figure it should hold up okay. The passages to and from the oil separator were completely clogged with oily carbon debris, so I'm glad I jumped on that.

Put a little over 6,000 miles on my 2006 S60 since I purchased it in early February so I did my second oil change yesterday and am going to do a drain and fill on the transmission fluid since I have no record the last time or if it was done. I am guessing that it was at some point before the records I have, but it cannot hurt. My only issue is that I need some containers for the spent fluid so I know how much is being taken out and need to put back in. The only empty container I have is a 750ml bottom that my Redemption wheated Bourbon came in. I don't drink milk or 2-liter bottles. I will have to figure that out before I start draining.

I thought that the ETM repair by Xemodex had a lifetime repair if you were the original purchaser of the unit? Is this no longer the case?

My car is fitted with a Xemodex unit, and I started having the occasional issue with it. It was then I found as I did not purchase it all bets were off. Not impressed.

I drain into a cheap, plastic, rectangular dish wash tub that has graduations marked on the side. Purchased from the dollar store. Not great accuracy, but OK and large enough to catch the fluid drained.

After 2.5 years or 80,000km my rear brakes were due. I think I got my money's worth out of the brake pads

Usually I don't run them THAT far down but I simply forgot that I wanted to replace them when I put the winter wheels on, so it was a bit of a surprise in the spring(ish)
