Question about 2002 Volkswagen Passat

2 Answers

ABS fuses (#7, 16, 41) missing from 2001 Passat.

Checked to see if our ABS fuses were blown as the ABS and brake warning lights go on when started along with the three loud beeps. Had read that it could be malfunctioning due to blown fuses not getting power to the module but when we looked in dash fuse box could not find the three ABS indicated fuses (#7, 16, 41). Could they be under different fuse numbers? And if not, where should we insert the new fuses as no ABS fuse location is specified?
Any help would be great as it's failed three smog checks and we're almost resigned to buying a new module at $800.
Thank you!

    Thanks for your response regarding our 2001 Passat ABS prob.
    The abs/brake lights went on in the summer (we were told $1,000 to fix it so just had put off the repair) . We'd never checked the fuses before so don't know if they were missing before then. A mechanic told me not all cars need them. (Our manual doesn't mention them but the fuse card in the box does list those three but perhaps it's a generic VW card ?)
    In any event, we've always passed the emissions test (last was 2 yrs ago) but then the abs/brake lights weren't on then either.

    Thanks for your very helpful comments, Steve and Mike! Appreciate the instructions on how to check the sensors as had no idea how to do so. Still plan to look at them (and hope that wasn't the prob) though we did go ahead with the new abs module (another bosch from VW) since the registration was already overdue. Good news is the car passed the smog test finally (after not connecting at 3 stations)...a relief. It wasn't cheap but the independent VW shop I found was better that the two dealers in the area, and included a re-scan and clear coding. It will be such a relief not to hear those three loud beeps and see those lights.

    Thanks again...this is a great resource.

    I have the same problem the only different is that my car is a 2000 Passat turbo.

    couple quik questions.... have the abs and brake light always been on or did they just come on recently? also if just came on recently were these fuses missing before the lights came on? next you said you failed emmisions inspection.... was it because of the abs light or do you have an emmisions problem as well?

Most likely Steve is correct about the sensors, they are the most common problem, if you tinker with cars yourself you can try them at home first. jack up one corner at a time ...the sensors just push in to a copper shim in the hub. move back and forth a few times with pliers and they will come right out. look over the wires to be sure there is no damage < chunks of ice and froxen snow are know to cause broken wires> if wires look ok spray clean the reluctor wheel on c/v joint and the sensor itself. if you see metal fuzz looking stuff on the sensor ,that is junk from your brakes and needs cleaned off. the metal dust causes the trigger in sensor to malfunction. do all 4 corners one at a time then drive the car if abs light and flashing brake light go out your fixed but still should have codes cleared to make sure there is no there problems. if this doesn't fix it best bet is to have a dealer you trust to look it over , brakes are important. once abs light is out see if you pass your inspection, if not ask why then post on here what they tell you and we'll address that . good luck.

Have te sensors on the hubs looked at. Basically they work like Electro magnets the module sends power down the wire to the sesors on the wheel and it creates a magnetic field btween the tip of the sensor and te drive saft end or the rear hub. If any part is dirty or corroded the ABS system goes wonkie. More than likely the front CONSTANT VELOSITY JOINTS that are faulty. Not cheap but Alot cheaper than the ABS module by a few hundred dollars.... Steve in the uk

ABS light on, STOP warning on, Handbrake light on, bleeping sound


Get a second opinion as you are dealing with brakes here.
Things to get check/get checked
Brake fluid does it need topped up.
Fuses covering these systems are there any blown.
Brake pads are they worn or are the sensors damaged.
ABS sensors are they damaged.
Handbrake cable to front wheels worn or stretched.
Handbrake sensor faulty.
Again if it's brakes get these things checked out sounds like a faulty abs sensor but best get the rest checked to be on the safe side.
Hope this helps

Abs light has come on saab93


THE ABS WARNING LIGHT HAS COME UP

It means there is an issue with the anti lock braking system (ABS). If the warning light has come up it is likely that the ABS is no longer functioning. It is still safe to drive the car and it will brake as normal but the anti lock safety feature will not operate.

You need to have it checked out for faults. The most likely cause is a failed ABS wheel speed sensor which needs to be replaced. There could alternatively be a problem with the ABS pump which is causing the warning.

There is one item you can check yourself. There is a dedicated fuse for the ABS pump/motor. Check the owner's manual and locate the fuse for the ABS motor and check that the fuse has not blown. If it has blown replace it with a fuse of the correct amperage and road test the car. (So if it is a 40 amp fuse for example, make sure a 40 amp fuse is used to replace it.)

Abs warning light on after trailer with bad electrics was attached


Check your brake lights and see if they are working. there may be a blown fuse. Also make sure that your trailer hook-up on your car is not causing the barke lights to stay on all the time.

If this does not find the problem, your ABS light being on may not have anything to do with the trailer being hooked up. You will have to scan your ABS module to find out why it has turned the light on.

Abs light stays on, but brakes still seem to work ok


The ABS warning light means there is a malfunction in the anti lock system on the brakes. This will not affect the conventional braking system on the car which will continue to operate normally.

The car is safe to drive as long as you recognize that it will now be possible to lock up your wheels under hard braking or when braking in slippery conditions where the tires have poor grip.

The problem with the ABS malfunction is that you no longer have an anti -lock assistance on the brake system so in certain conditions, such as on a wet road, you will be able to lock up the wheels on the car when you brake hard. The anti-lock system identifies and retards lock up (by releasing brake pressure on a wheel or wheels) and allows the wheels to keep turning slowly even when you have full pressure being applied on the brake pedal.

The ABS system relies on sensors and if one or more fails you will get an ABS warning. It could be a faulty or dead sensor but it is impossible to say without testing and inspecting the vehicle.

The ABS has it's own fuse so you can check the fuse box in the car to ensure the fuse has not blown. The fuse location is shown in the car's owner's manual. A blown fuse would trigger a warning.

You should take the car to a competent brake specialist to have it checked and the problem rectified.

It's much safer to have the ABS in operation.

Abs light on and brake light blinks


This is indicating a fualt with the abs and braking system. Volkswagon is very proprietary and a trip to the dealer may be nesssary. If you look in your owners manual it will tell you what all of the warning lights on your dashboard mean. I would also check your battery, if your battery is not putting out optimal voltage for this car then it will play all sorts of havoc with your warning system by throwing false warning and such. My 07 passat did the same thing, I would get in the car and every warning light on the dash would light up like a christmas tree and then go off a little while later. I replaced the battery and I never had a problem again.

2001 Volkswagen Passet brake lights don't work


It should be printd into the fuse cover. If you can't see a fuse blown, then thats not your problem. Check the clearing at the top of the brake pedle to the brake acuator and if there is an overlarge gap it will not work the electrical circut.
