Hi guys, had my car for almost 4 years now, but still sort of a NOOB when it comes to some things. Hope you can help!
I did a full brake job with new pads and rotors and a bleed at a small local TDI club meet last month. The pedal felt kinda soft after leaving, but the brakes grabbed pretty well so I wasn't concerned.
About 50-75 miles and two days later the ABS light comes on while driving around town. Now it comes on within a minute of moving the car every single time I drive it. However, if I just sit there it will take much longer to come on.
I brought it back to the guy's house where we did the brake job and we scanned it and VAG-COM said, "ABS Hydraulic Pump, Implausible Signal - Intermittent." We were recommended to bleed the ABS pump, following the Ross Tech procedure. However, the procedure on Ross-Tech's site doesn't say what to do after you push "Go!" and the on-screen instructions were not very helpful, so after a while it would just say "N/A" all the way across...
After searching, it seems like I may not have been holding the pedal down long enough??? I saw another thread that said you have to hold it down for a while until the pump comes on.
Do you think that bleeding the ABS pump should take care of this issue?? Is there some way to check the signal other than Vag-COM???
Also, since my car is a 2002 model year and some of them had a recall on ABS pumps, I asked the dealer about the date of manufacture and they told me it was 10/2001, which puts me just outside of the recall period. But couldn't they still have been using the same part numbers for another month??
