Citroen C4 Grand Picasso Part 32 - Diagnosing a knocking sound - FAIL
HTML-код
- Опубликовано: 14 окт 2024
- I started to hear a knocking sound coming from the front so I decided to take a look.. I got it up on the wheel ramps so I could get underneath. Unfortunately, I didn't find the source of the knocking. I also removed the air cleaner with no success. With the MoT due I decided to leave it and see if the knocking problem would be picked up during the test.
EDIT: When it went through the MoT, it failed on loose nearside damper bolts so that was probably the cause of the knocking sound. I'll know once I've replaced the front coil springs (the offside one was broken so I've got to replace both).
PLEASE NOTE: I’m just a DIY mechanic. I try to do things the correct way but sometimes I have to manage with what I have. Please treat this video as a “how-I-did-it” rather than a “how-to”.

Did u check the 2 strut bolts that bolt to the hub? Did it not mention that they were loose on the mot fail sheet?
Yeah, that's what it is. It will be coming apart when I replace the front coil springs.
Hi did you find out what the knocking noise was I now have it was it the driveshaft? Thanks paul
It was the strut top mounts. I've since parted company with the C4GP and it has been replaced with a Volvo XC90.
Could it be a top mount bearing or broken spring? I've had that on my wife's astra make the same sort of noise.
The MoT picked up a broken offside coil spring but that wasn't the cause of the knocking sound.
Possibly slack in the drive shaft or bushes of some sort. I'll wait for you're second part to find out what it was.
Ian, it was the bolts where the damper is attached to the upright. They were loose. They've got to come off because I need to replace both front coil springs. They'll be getting some thread lock on the when I put it back together.
I had the same issue I think and found the orange seal around the turbo air pipe was broken and car was jaddering and making a noise at take off. Once replaced for £4 on ebay car is running extremly smooth and all noise and jadders are gone
It was the front strut tops as I found out in a subsequent video.
Having a similar problem with my regular C4 1.6 HDI 2008.
Rattling noise appeared out of nowhere - on the drivers side somewhere under the hood closer to windshield when driving over bumps and smaller holes. Interesting thing is that it stops when I press the brake. Mechanic checked everything that could be suspicious, plastics, bolts, nuts, tightened everything... brakes, stabilizers and steering column is good.
Any hint or help?
Could be a strut top mount. That's what the problem was on mine.
@@Parknest Thanks, I will look into it and get back the results. Noise is driving me crazy :)
So, the problem was with stabilizers. Cheap repair but hard to diagnose. No rattle anymore!
I've kind of similar noise in my car. Where you are based in UK
The knocking sound has come back to haunt me. It now needs new strut tops. My accent should've been a big clue. I'm in West Yorkshire.
@@Parknest i have a similar sound diagnosed as a steering rack advised to leave it alone untie to get worse
what you think
@@SalemAbuOmar It was the strut top mounts which were replaced with genuine Citroen parts from the dealer.
@@Parknest maybe different with mine
Its come with moving in start car move
As mechanic describes
Thanx
no idea tho ali maight have rihgt he is much better with car than me tho once one of my friend comes with nois at accelerating and source of weird noise come out from alu sheelding on top of exhaust doesnt looks damaged tho at some rpm gets the right vibration and 2 of 6 holding screws wasn´t hold it anymore tho it was invisible looks ok tho as you pull it then you can see it is loose 👍😀👍
My MoT man found out what the problem was and it was one of the MoT failure points.
