Clicking sound while driving

[Blackhammer]

Evening all.

Sometimes when I driving there is a loud clicking sound coming from the front of the car. It's not the vents, it happens when driving there is no noise when stationary.

The quicker I drive the more louder and more frequent the sound is, as I slow down the so does the clicking sound. When I'm not accelerating or going downhill the sound is less frequent. I don't notice the noise on a short drive. Sods law will dictate I will take the car to a garage and it will be silent!

The car drives the same, no warning lights. Car is a CLK 320 209. The noise is annoying, only use the car on weekends but the noise is driving me mad.

No issues with car when it had B service 2 months ago, and it an MOT last week with no issues, help !

Thanks in advance

Difficult to confirm without hearing/seeing it but my initial guess would be a dust shield at the back of the brake disc.

Possibly something trapped in it, like a stone or, more likely, it's got bent and is rubbing on the disc.

Check the parking brake cable is securely attached along the prop tunnel

Wheel bearing(s).

Duff brake pad spring(s).

I would check the inside of the tyres to ensure no damage or bulging in the tyre wall.

Thank you I will mention this to the garage tomorrow when I book it in

I had have wheel bearing issues before on cars and the wheel shakes and vibrates at speed, this is just a clicking sound

Might sound stupid, but worth ruling out as simple as it sounds - check to make sure none of your tyres have a stone or something stuck in the tread.
I had a similar annoying ticking on a car years ago, and was very relieved when i finally found the little stone in the front tyre.
Fingers crossed it's something trivial like that!

A stone in the tyre can cause all that noise! Crickey! I will ask the garage to check for stones in the tyres as well. I can't see anything obvious but need the car on the ramp to check this properly

Yup! I've definitely had it also. Very annoying.

So much so I had to locate it.

Turned out to be one of those flinty driveway / beachy type stones (technical terminology!).

Could be parking brake not releasing fully. Mine does this now and again. Put the parking brake on full with a firm shove on the foot operated button. Release. Repeat a few times. Then drive it. If it’s sticking a bit that’s usually enough to release mine fully! I’ve also had a chirping dust shield behind the discs which was sorted by me bending it slightly by hand (they are made of thin metal).

+1 on that. This is why i regularly check my tyres.

Let me guess a sort of "shik, shik shik" noise as the shoe is not quite clear of the drum? - I know that sound well, and it does go away after a little while. That doesn't stop your passenger asking what the noise is.

 

[Blackhammer]

The noise is intermitant don't notice on a short drive, but once it starts it doesn't go away. The car is booked in for Saturday so will see what garage says

On my old CLK I had a similar noise. The clip holding the parking brake cable had come loose allowing the cable to rub intermittently on the turning prop shaft. £50 to sort it out!

 

[Blackhammer]

A little update, it was in fact the parking cable clip that had broken. The mechanic said it was a very common fault, £30 all sorted, thanks for all the suggestions.

I once bought a 2001 Alpina B10 V8 and I noticed it clicking at the front.

Was wheel bearings but that was the only symptom.

I'm used to a drone when they are gone from previous cars although I imagine if left long enough you would eventually get shakes and vibrations.
