... my dad just called because the ASR and ABS lights came on in his S320, which I had just done all four rotors on. I think it's safe to assume I screwed something up in the process of removing/replacing the calipers, or bleeding (which I did because the pedal was spongy when he bought it), but he wanted the car back before I had a chance to drive it around much (I took it out to bed in the brakes and no lights came on during that drive). Is it OK for him to drive it to my house (20 miles) so I can look at it? I was thinking I probably damaged a sensor but don't want him to drive it if it's something more problematic. Of course, I'm stuck at work, can't look at it, don't have the manual, etc.
