Is your odometer and speedometer still working?

As long as your master cylinder has sufficient fluid and the brakes work, then its safe to drive.

What you describe sounds like a bad ABS wheel speed sensor. Its a common problem and your 2006 has one sensor at each wheel.
The hard part is figuring out which one is bad.

I recommend taking to a shop that can scan the ABS system and identify the bad sensor.
Wouldnt hurt to have all your brake pads checked too.

Under the hood, drivers side. Up against the firewall. Has a yellow cap.
Check owners manual if you cant find it.

ABS is antilock braking system.
The wheel sensors tell the ABS computer if one of the brakes is locking up.

So, if one of the sensors is not working, then it wont tell the ABS computer that the brake on that wheel is locked or not but that doesn't mean the wheel will get locked, right? And by the way, why is that a brake might get locked?

A bad wheel speed sensor will cause the ABS system to stop functioning.
You will still have normal braking ability.

Have you ever been on slick roads, slammed on the brakes and had the wheels lock up?
ABS prevents that from happening.

On an 06 the ABS is also used to apply brakes to a wheel that is free-spinning. 05s used limited slip diffs. 06 applies brakes to wheels with no traction to transfer torque to wheels with traction.

How much it's used would depend more on how you drive. It's simply the 2006 model can use the ABS system in a different additional way.

I suspect one or more of the communication lines from the hub sensors has been damaged. On my 06 the front hub lines had come loose and were actually contacting the tires. Perhaps something has happened to yours to cause an intermittent open / short / ground in the communication wire.

So, for what I understand ABS is for, is for actually when it rains and you start planning on water. So if it is not raining I can drive safely without ABS on a road trip, right? And as long as I dont need sudden stopping, I am ok?

What he said.

Sorry, I misunderstood. Your signature says 2006 CRD.

Anyways, No, I didn't disclude the sensors in the hubs.

The light problem could be caused by any intermittent problem from the hubs, hall effect sensors, and anything and everything from there, up to and including the ABS computer module, including all wires, insulation, system grounds, etc.

But it doesn't it wouldn't put your life at risk to drive, unless you drive in a way that would do that anyway.

If you can't afford to get it checked out by someone who understands the system and how it works right now;
If you can mentally deal with a light that comes and goes;
If you can drive sanely and safely;

Then drive it. And enjoy it.

However, X2 on Flash's Advice, as soon as you can afford it.

Happy New Year

A bad wheel speed sensor can also be and indication of a bad bearing.

Oh, well, if I have to change all bearings, I would better sell the car...
