After brake replacement, is ABS permanently disabled on one wheel?

Hello community,

I recently replaced the brake discs and pads on my Golf 6 2.0 TDI.
Everything was fine and it's stuck.

Since then, I've experienced a clicking sound with every, even the slightest, braking, as if the ABS is activating on one of the wheels.
However, no warning light illuminates (if it does illuminate at all, when ABS is activated).

How can I best check ABS rings or sensors to determine if they are responsible for braking behavior? The rings are, in my opinion, located within the powertrain, so they are not easily accessible from the outside. Okay.
Are error codes generated that can be read out (the on-board computer shows nothing)?

I hope you can help me, because the rattling noise every time I brake is so annoying...

Thank you & best regards!

What does the fault memory say?

For example, with VCDS, you can compare the wheel speeds for each wheel in the ABS/ESP measurement blocks.
Wheel bearings must also be in good condition and should not have any play. Also, no metal or rust particles should be present on the rims/sensors.

Were the brake discs and pads on both the front and rear axles replaced?
At what speed do the sounds occur?
Which wheel is making the noise?
You describe it as a clicking sound, do you mean the typical valve noises during ABS operation, or is it a metallic clicking?

By the way: The ABS warning light illuminates if there is a fault in the system.

Were the brake discs and pads on both the front and rear axles replaced?
--> Only the front axle was replaced. Rear axle: only tires and saddle were removed, the brakes were still sufficient.

At what speed do the sounds occur?
--> Always when braking, the louder it gets with more force. Barely noticeable vibration at speeds above 120 kmh, sounds like slight imbalance...

Which wheel is making the noise?
--> not precisely locatable...

You describe it as a clicking sound, do you mean the typical valve noises during ABS operation, or is it a metallic clicking?
--> No real ABS "whining" sound, as it's not perceptible through the brake pedal.
--> The rattling changes proportionally with speed, the drive shaft, and the transmission, which I can rule out because the behavior occurs regardless of the gear being engaged or the vehicle being in neutral.

Incidentally: The ABS warning light illuminates when there is a fault in the system.
--> No error message or warning light

I have now replaced the discs again, but the noises persist.
Could it possibly be the handbrake? The rear wheel and brake caliper have been removed, but the pads and discs were still in good condition. Is there perhaps a small mistake?

Thank you for your help!

Hello community,

I don't know what the cause / the error is for the aforementioned. The noise was present, but the clicking/clacking sound is no longer occurring.

Maybe it has something to do with the tires.
Over time, the summer tires have improved, and after switching to winter tires, the problem is no longer noticeable at all.

Nevertheless, thank you to everyone in the forum who tried to help me solve the problem!

Thank you for the feedback, it's possible that the differences in rolling circumference between individual tires were too large.
