Finished up diagnosing and hopefully finally fixing the abs/tracs issue. The reluctance ring was ok as were all of the sensors. Took the abs module out reflowed the joints again, but with a more powerful soldering iron. Put everything back together and so far no lights even after a nice long drive with plenty of braking. I noted the date and am curious to see if the lights go back on again and if so when. The nice thing about being familiar with the car is the whole procedure went a lot faster than last time. Even getting to the mounting bolts seemed relatively routine. My only stumble was when I put the bolts up on the area near the windshield one fell down the driver side drainage hose and was stuck somewhere in the middle. Of course my magnet was in the other car so I had to manipulate the hose until it fell out the bottom. Took a little while to figure out where the heck it could have gone. I looked for the other things I've lost in the past but they were no where to be found. Looks like I'm not ready to graduate volvo boot camp just yet.

Au contraire - you have slain the broken Volvo dragon...

or

staying in character of boot camp.

You...are ...no longer...maggots.

Well done!! I do circuit board repair on stuff, took one look at this, and called Matty. I think most don't have a powerful enough soldering guy to heat these suckers enough, and not enough heat is not your friend on CB repair.

Thanks. Ended up using a 140 watt soldering iron and heated the pins until they just started to move. I figured I had nothing to lose and would either fix it or fry it. Hopefully it was the former. The first time I had used a 40 watt and it took forever with obviously poor results. This time it took about 5 seconds per pin with the larger ones taking a little longer. I very much appreciate all the input. My wife pretends to care, but we both know the truth.

Thats great info

140 Watt Iron
5-10 seconds per pin.

That might save a lot of trouble for others.
