I bought the car 2months ago, and sometimes the abs+brake light went on.

Last week i took a trip about 2hrs and was on the road when i hit a bump when all three lights came on abs ,check eng ,brakes.

When i came to a stop in went into limp mode, downshifted manualy and it worked fine. Since then took to a trans shop drove it and he said it was fine, he got these codes p0722,+p1648 does anyone know what this might be?

Also check your axles for tightness. I had one that the axle was ready to fall out, everytime I hit a bad bump, all the lights came on

gotta agreee with JRL on this one, repair the ABS module FIRST. I wasted $80 on a new abs sensor (that's the code that came up). Its a bad abs module.

i just got my car back,it was the speed sensor,and a wiring problem,it took the mechanic a few days to find it.the code po722,p1618,went with the speed sensor,the lasy code never went away, so no speedometer,so he went threw the wiring and found it. the best 300dollars i ever spent. volvo wanted 150 just to put it on the machine.
