Over the last year or so, my brake light will occasionally flash during a drive cycle and beep incessantly. I know the main cause of this is brake fluid level, but it has always been completely full when I check it.
The last two days, it's come one and beeped the every drive cycle and for much longer than before, yet the brake fluid is still full. What else can cause this light to come on and beep? I have read stuff on the forums about the ABS module going out, but doesn't that cause the ABS light to come on as well?
'00 Beetle, 1.8t T3S60, Brute Rods, Supertech Valve train (stock cam shafts for now), port and polished small port head, custom FMIC (pain in the a** on a Bug!), Bosch 440cc injectors, 3.5FPR, Catch Can, 2.0 Coils with Iridiums, Wilwood BBK, too much other stuff to list, too much $$ spent.
It is a 2000 S4. I checked the fuses and everything seems fine. Even got to the point of removing the filter from the inlet of the reservoir and fingered the float to make sure that it wasn't stuck. The constant beeping tailed off by the end of the weekend though.
Car is in the shop this morning to get a wheel bearing replaced (was humming), so hopefully VAG-COM will have the answer. Will update this if they find the problem so if anyone else runs into this, they know...
The shop was unable to find anything wrong with the car a few weeks ago, though it wasn't beeping/flashing for them when it was in, go figure. Car had stopped beeping/flashing until this weekend, took it in today while it was still doing it. There were no codes in the car related to this. There is fluid in the reservoir, and they even tried jumping the connector for the level sensor to rule out a bad sensor.
So this is either wiring between the connector and the cluster, or a cluster. The only other thing that I think this could be is that my brake wear indicator has been on for a very long time (the wire got caught on something and broke over a year ago, there is plenty of pad still) and does anyone know if there is some sort of backstop timer that will cause the car to flash/beep, thinking that I've ignored the wear indicator for too long?!?!?
please post what u find out is wrong
Check your front pad thickness.
In addition, fix your wheel speed sensor as your ABS will not function without it; should the occasion arise for ABS to engage. Flipping or unplugging the sensor will not get rid of the light, as if just responds with a simple flag state to show the ECU if the reservoir has fluid in it, no matter the orientation.
Fixing a problem with the braking system by unhooking random sensors until the dash lights go away is a terrible idea and will likely end up with you getting yourself hurt or even worse, someone else. VW put the lights in the dash for a reason.
I haven't checked any of the ABS wiring, but I'm fairly certain that's not the issue since the ABS light is not coming on, just the red parking brake light. I'm going to check the pads (and the wiring for the wear sensors) next, need to find time to get the car up and get under it.
But in the meantime, the buzzer coming on every minute or less is getting very annoying. Does anyone know if it's easy to unplug the buzzer in the cluster?
You made it sound like the ABS light in your previous posts. IIRC the handbrake just pulls a cable to engage your rear brakes, unless you have the motorized version. There should be a sensor under the handbrake lever where it pivots, pull the plastic and check the angle sensor. When I get home tonight I'll see if I can post a diagram.
Hey guys please check your the three fuses on top of your battery! The 10 amp ones. Mine was doing the same thing and all the fuses were good but were not making contact! move them around and see if it goes away! Let me know if it fixes your problem. Thanks!
