    1. Determined the solutions

      After all this time I finally managed to fix my car completely and so now I'll explain what I did. I basically had two separate problems, being the occasionally weak brake boost and the pulsating...

      Been in the process of moving and I finally got a chance to bring my car in for the wheel speed sensor problem that I suspected. I went to a VW dealer and explained how the pedal was pulsing at slow...
    3. Found the fix for weak vacuum!

      Last night I tested suction presence from the bottom hose with the engine running and pedal depressed...there was never any. Afterwards I could suck air quite easily through the bottom hose while...

      Yep, there are two check valves on the vacuum line coming from the intake manifold and both are functioning properly. I just tried looking under my car for the end of that hose and it appears that...
    5. Interesting, I didn't think that the tee fitting...

      Interesting, I didn't think that the tee fitting assembly looked OEM either (no part #/doesn't say VW on it and it's not a check valve, just a plain tee). I've done no mods to it but I've found other...

      Thanks, I'll definitely get my wheel sensors checked out the right way. But if a wheel speed sensor is the cause, then it must mean that the weak brake boost is being caused by something else...

      The 1.8T is a high compression engine (9.5:1), which is why they recommend that you use at least 89 octane fuel. without the turbine boost the fuel mixture isn't leaned for the lower pressure so it's...

      I've got my own thread here with more details as I'm still looking for help......
    9. Can anybody help me?

      I have a similar problem with my 02 GTI 1.8T that could be caused by a bad ABS control module. My brake pedal pulsates at slow speeds just before coming to a stop and also in sharp turns. This has...
    10. I thought that the boost vacuum pump was inside...

      I thought that the boost vacuum pump was inside the intake manifold, but I'm not positive because my repair books aren't very good. Anyways when I first bought my car, this bottom hose was completely...
    11. What is this hose connected to my brake booster (pic included)?

      On my 02 GTI 1.8T (automatic) there is a brake vacuum leak someplace. A mechanic told me that it was the brake booster that was leaking but I replaced it and it didn't fix it (I replaced it...

      The water did something to your electrical system. Maybe as simple as a fuse in the engine compartment or maybe something harder to find... I washed my engine compartment one time and water got...
    13. Weak brake boost when engine is cold and pedal pulsating at slow speeds?

      Thanks to all for helping me out...

      I am trying to fix two brake issues in my 02 GTI 1.8T. I am not sure if they are related or not but they seem to be getting worse and I've already stumped a...
