My mystery clonk

Featured Replies

So, literally sitting in the seat made it clunk? Mines certainly not that bad! Mine is definitely when going over bumps and with steering input going on.

There are no clunks on mine whilst steering lock to lock whilst at a stand still, how about yours??

Have you tried pushing down on the wings to see if the suspension makes any knocking noises when you bounce it? (springs are a bit hard for this, i know) I don't get anything when i've tried........... I'm about as mechanicly minded as you, so thats the best i could come up with! :o

I hope you get it sorted mate, i thought mine was annoying/worrying but yours sounds alot worse!

Clonking when sitting down is VERY occasional, no clonks on full lock moving or standing and I have bounced on each front after its been sitting overnight and not a peep still.

I also tried at work before going over the speed bumps... must of looked like a right loony to people walking through the car park :rofl: Then it still clonked over the third or forth one

Maybe its just telling me it wants to be lowered? ;) Or maybe i should of just bought another car

Quick update...

Took the car down to unit 18 yesterday for a service and Ali had a look over the car for me :). Nothing seems to be knackered, and he seems fairly convinced its the arb bushes sticking/releasing against the arb and his opinion is good enough for me.

Had some lube applied, but as long as I know that its nothing worth worrying about I'm going to do exactly that

That's how I deal with 95% of the noises I hear from my car. :rofl: [turns up radio :speaker: ]

Good to hear...... I've managed to switch my brain off to my noises now, i'm no longer hearing them.... there still there, i'm just tuned out of that frequency now..... I'll get it checked out when i have it serviced next.

Has anyone arrived at a definitive answer to the elusive clonk?

I've got it coming from the n/s front mainly at low speed on uneven surfaces. The car has been into the dealer twice over this but it remains and is very irritating. Gearbox and dogbone mounts checked and greased so far but I need to guide them as to what to do next it seems.

nope :(

I asked 3 places to provide me with quotes on getting the top mounts changed, none of which have got back to me even after a prompt for each. The one mount seems to rattle when i press on the strut tower so i think its on the way out regardless of whether its the cause of my clonks

Probably just going to wait until its so bad I can show someone and they can hear it, although it annoys the buggery out of me

Again have had this replaced:

arb & bushes

drop links

front and rear wishbone (console) bushes

Its not the engine mounts, they were changed start of the year and they made a completely different noise.

This is either a metallic clonk, or a squelchy metallic wobbly noise under cornering. Hard to explain

Sorry to hear you still haven't tracked it down. I would describe my clonk/clunk/bonk sound slightly differently. It reminds me of the sound a tuppaware box makes when you kick it, if that makes sense. Does this remind you of anything you have already experienced and tracked down as you seem to have some experience of the various noises the car can make. It does seem to be suspension related.

not had too much experience.

only one that was bad other than this is the engine mounts. Does yours just do it over bumps? My engine mounts knocked over bumps, or dabbing on/off the accelerator in 1st and second... basically anything that made the engine wobble.

I had them lubed, made little to no difference. Had the dogbone and engine side mount replaced, and it was silent... for 2-3 months anyway until this knocking started lol

Just had my brakes replaced on the front and i have a high pitched squeaking when turning right after 20-30 mins of driving lol

I give in. if someone offered me a half decent trade i'd find it hard to resist

Did anyone get to the bottom of this problem? I've got an annoying clonk from the nearside front. The car is standard vRS and the garage have had two goes but can't find anything wrong. It does it when driving slowly i.e. sub 30mph and when the nearside suspension is perhaps slightly unwwighted and I am travelling over moderately rough road surfaces but not over speed bumps. Interestlingly the sound disappeared after being driven in heavy rain but returned a couple of days later when presumably whatever is causing the problem dried out.

Any help on tracking this down would be great.

Afraid not mate, mine still clonks randomly when it feels like it. I try my best to ignore it, but its depressingly persistent

My 06 Elegance Combi 1.9TDI does this too. Random, occasional clunk. 47k, so possibly topmounts. Easy to self-fix??? Any ideas?

Not convinced it is mate, which is why I haven't bothered with mine. Surely if it was the mounts, it'd be more frequent going over speed bumps etc.

It seems to do it quite randomly and much less frequently when warm. i get the feeling its something rubber slipping. Sounds mostly like a denting a tin can, then squeezing the sides to pop it out.

Sure i've heard it coming from the back too

arghhh

I had a knocking noise from underneath whilst setting off at junctions, the bolt from the dogbone mount to the gearbox had fallen out. Leaving the gearbox to slap against it whilst setting off.

Its probably not whats at fault, but its just another thought.

:) pretty sure its not that mate, if it was something i could consistently reproduce i'd hopefully be able to find it... its just completely random... although more prominent when cold/wet

I have finally fixed the clonk/clunk/bonk sound that has plagued my low mileage 07 vRS for many, many months.

Some history, the Stealer's service department greased the nearside gearbox/engine top mount a couple of times as per the TBS and yes the sound disappeared for a a few weeks but then gradually returned. That was all they could offer whilst the car was under warranty - SHAME ON THEM!

After wrapping a towel around my head and meditating on the matter and also reading about so many others seemingly being unable to find a solution to this not uncommon problem, I bit the bullet and had the mount changed (revised part number 6Q0199555BA for the BLT engine) at an all in cost of £130 fitted and finally I have tranquillity. So there is ho need to spend fortunes changing consol bushes, dog bones, strut mount, ARB bushes, drop links etc. just try renewing that humble engine mount.

I hope this helps others who are plagued by this design fault - really Skoda you should know how to build an engine mount by now.
