2003 Passat 1.8T Shaking and Pulling to Left

[RangerGuy25]

Hey Guys,
Over the weekend I replaced the front brakes on my girlfriends 2003 1.8T Passat. Everything was fine for a couple of days until she called me this morning and said there was shaking in her steering wheel, a slight pull to the left and a "loud" noise. She said the shaking and pulling seemed to stop when she accelerated or stepped on the brake... I'm not sure about the noise. My first thought is that I may have forgotten to fully tighten the lugs on one wheel ( stupid me..). I was just wondering what other thoughts you guys might have since I won't be able to see the car until I can drive to her work later this evening. Any info is appreciated. Thanks.
