Quick back story. About a week ago my S40 just cut off while driving. I put the vehicle in park, but could not pull the key. At this point I figured it was a power issue. I opened the hood and lifted the battery cover. Somehow this moved something and the headlights lit up. After that nothing else f...

Just an update for future viewers. I found a 150amp fuse at NAPA Auto Parts. I attached it to the cable #13 on the image above with a nut and bolt. The other end of the fuse mounted right up to the terminal #2 on the image above. It actually does not look to bad. Any way everything works fine. I wen...

I wouldn't take another look. I believe it's fine. I see that slight movement a lot.

That said you need to check your work - start with the timing as this is always a tricky part. See here: https://www.matthewsvolvosite.com/forums/viewtopic.php?f=10&t=87735 Then look at ...

P0011 = ECM-5F Camshaft reset valve. Diagnostic trouble code (DTC) information Condition The engine control module (ECM) calculates the camshaft position in relation to the crankshaft using the camshaft position (CMP) sensor and engine speed (RPM) sensor signals. The control module adjusts the camsh...

The temps are a fictional value calculated from ambient and increased for time brakes are on and reduced for time off brakes. No temp sensors are used. Ignore this, as it is a symptom of the network issue keeping ABS module from knowing ambient temp. There is likely a network wire issue. If you move...

Preamble, mileage on car 239748 I thought I detected rough running for the last two week at startup and cold idle, but after 60 seconds idle was smooth, so I took no action. I did check #3 plug and found it at 0.032 with some tip wear, and meant to compare it to new, plugs have 24k on them, Volvo OE...
