rough week for the s4...

[cali kid]

So this week my brake switch, abs module and vehicle speed sensor all went down. I haven't gotten under the car yet but I'm hoping that the speed sensor just got knocked loose.. anyone know where the vehicle speed sensor is andhas anyone else faced these problems? I was told there are two ddifferent types of abs modules for our cars and depending on which it is I can either have it rebuilt or have to buy a new one.. any insight would be great.

Going through the same thing tc abs light on with flashing brake light. Comes on when I start driving. Hurting acceleration and braking is weird feeling. If I turn tc off as soon as I start the car-the lights don't pop up but still making car sluggish during acceleration. Brake fluid is not low. And pads and rotors are good to my knowledge. I'm not sure what the culprit is I'm hoping it's not the abs module

Has you check engine light come on yet? The codes I pulled saylid that it was the vehicle speed sensor

I have the little cheap advance auto scanner not was only getting a p0305 and p0307 code I'm wondering if I need to replace a half moon seal. But before all that I remember a friend of mine plugging the vag-com and mentioned something about the brakes and had a hard time pin pointing my issue and had to have the software scan through all the computers or something of that nature.

I hit a few nasty potholes on Highway and I'm curious if the issue is a bad wheel bearing. I just started getting a tiny thumping noise from passenger front wheel. Tires are not flat or bent to my knowledge
