Clutch Clonking noise??

i've had the same problem..is your car lowered?

With so little information it could be anything really, brokern engine mount, sticking clutch realise bearing , knocking exhaust etc etc. Occasional problems are a real bitch to sort out.

I had the same noise on my cupra, i have seen a few posts about this. mine stopped, maybe it will just go like mine did

I am having the same problem in my cupra, mine sounds like a metallic clunking, and only does it in reverse and 1st. My car is totally standard

the bolts under the front chassis need to be retightened with a special tool.because it are spêcial bolts and the whole front drivetrain is from alu they need to be checked every service ...i've had this problem on my cupra ...

i think in english the bolts are named stretch bolts or so?? they need to be tightened on kilos or pounds but i dont know wich metric system you use in england...
i hope you guys understand me a littlee bit

Stretch bolts is the right term. Are you saying the bolts need to be retightened in the same way alloy wheel bolts need to be retightened and checked after they are put on?

yes they do..i've had same problem with my cupra and some of the bolt where really loose...after everything was tigtened the problem was gone..after a trackday you can see that the bolts are coming loose agais so i mark the bolt now with red paint..

i wonder if mine stopped doing it after its service.....not heard the noise for a long time. will double check just in case i am blanking it out

i dont think much seat dealers are aware of the problem..i work at a seat dealer in belgium and i had to find the problem myself because seat spain didnt had any info about the problem..but if you use the cupra on trackdays or so or very hard cornering you clearly can see that the aluminium drivetrain onder the car really is moving..you can see that the bolts are moved a bit

I'll print this thread out and give it the dealer on Friday, its certainly a starting point anyway and I'll report back any findings.

It's a bit concerning there are bolts on the car that appear to work there way loose anyway, what would happen if they were to fall out - dangerous?

Whats frustrating is I've not heard the noise for the last few days - I would have thought if it was due to some loose bolts the noise would be heard all the time?

the bolts are not really loose because they are stretch bolts..its not that the drive train could fall off or so but it just moves a bit when cornering very hard..in my case i could see the marks in the drivetrain where the bolts previous had been en marks in the chassis that the drivetrain had been moved...if you take a big torque key you can easily give all the bolts a turn or two...

Hi, how did you get on when you visited the dealer?

I also have started experiencing intermittently this kind of noise, although mine perhaps is more of a groan noise, as if something is sticking on pull off, which releases itself after the car is moving. Seems to happen more when the car is hot on a long journey rather than when pulling off from cold.

ditto on old cupra ! and started recently on k1 !! sounds like a common prob

Hi, I am experiencing this problem on and off in my FR TDI. The car has had the steering rack replaced previously due to this same noise I am experiencing just now, dealer blamed a bearing inside the rack for the noise (seemingly they are sealed so old rack was binned and diagnosis never confirmed). This of course could be a load of horse manure!

Anway, on cold days it can be heard, but when the temperature is above 15oC there is no noise. Today when it was 4oC, there was very noticable metallic grinding and knocking whilst turning right at low speed coming form the passenger front wheel. I have suspected that there is an expansion/contraction issue involved and this revelation involving "stretch bolts" could be the cause???

Anyone got photographs of said bolts??? Are these the bolts that attach the subframe to the body of the car??

The noise drives me more mad than the rattles

Just got mine fixed finally. It went in on thursday and they replaced the CV Joint on the drivers side. I thought that it was a long shot but the dealers were adamant so i let them get on with it as it was under warrenty (car only done 15k), I collected it yesterday and the noise has gone completely.

Noise now definitely gone after Grants replaced the dual mass flywheel. Thanks to the entire team at Grants for your professionalism and excellent service!
