Question about 1998 Audi A4
Was the brake line removed ? There is no reason a brake line needs to be replaced unless the line was broken or damaged.
One way to check if your car has sensors, is to look for a harness that runs and is secured on the strut. Also check the hub, there is usually a slot in the back where the sensor is mounted.
Some vehicles come without brake sensors, best thing to do is call local dealer, supply them with your VIN and ask them if it comes with sensors.
What were the repairs done to your brakes ? What is the problem after the repair was done ? You may only need to bleed the complete system if calipers were replaced.

Ok you have either one of two main problems with it.
1. does it go in one direction only then jams the other way?
Ans. the plastic clips that hold the window to the lifting rail can break.
these can be replaced by removing the door trim & replacing though you will need torx type tools.
2. As with vw golfs & passets the motors pack up or even the wire can break on some of them.
Ans. replace the motor unit in the door or the cable & rail.
3. It is heardly heard tell of but the only other problem is that one of the wires in the hinge area to the door has broken.
4. we have had this one a few times but this would also include the interior lights & central locking not working as well as the windows.
The central convenience unit under the passenger foot well can go wonky & needs to be replaced, usually caused by water coming in through the heaters air filter when the water is trapped in the front of the car ( caused by rotten leaves stuck in the drain points & also happens to the A6 models )

It is common that ABS system do this from too much air gap to a wheel speed sensor. I would check the left front, since that is the side you had apart. Make sure the air gap is o.k and the reluctor wheel is the same size as the old one.

jack the car up saftely then take the wheels off .. then you will see the brake calipier turn the wheel towards you so the calipier is facing you . at the bottom of the calp you will see a small bolt at bottom undo this and lift prize the calp up then remove 1 pad the inside on where the piston is then put calp back down and put the bolt back in just to hold it in place then when you have done this put a large stronge screw driver in via hole in front to push the piston all the way back but make sure you do the evenly and piston goes in straight or it will get stuck same with all types of brakes. once you have done this reopen calp and take the other pad out clean all area with a wire brush and replace the new pads in place,, and retighten bolt etc , before you start the other side please make sure you pump brake peddle until it goes hard again. then do same to over side ,
hope this is a great help matdav69
