Hi I had the same problem for months. This was cause by a previous owner installing a 3rd party clutch. Swapping it for a genuine Hyundai clutch solved the problem
Was anything else changed?,  could you check or post itemised invoice if you still have it please.

No reply Mick  :( :( as usual 2 posts.  little detail , seems he may have petrol or diesel 1.6,.

This is like hearing an endless tape that you get to hate .  :crazy1:

Millions of after market replacement clutches are fitted, but they seem to only affect the i30 and only the DIESEL. Comeon!!  :crazy1:
They are also fitted after the original HY clutch has been blamed for vibration, Comeon!!  :crazy1:

They do not seem to affect the petrol - manual box i30.  :Juggler:

@mickd @tw2005
Trying to think laterally , what is common to the problem?  :workitout:
All diesel, not auto, only FD model, so far. Not every FD crdi.

Gerard (tw) and I worked on a problem where front oil seals were being pushed out.
This happens to some i30 manual cars (only petrol reported) because of clutch operating pressure .

It causes wear to the crank thrust bearings and therefore lateral play in the crankshaft and obviously, the flywheel.

Luckily the OP had an old timer mechanic who could methodically work through the evidence.
Between us we solved a rare, but well published GLOBAL problem. :drinks:

:link: High oil pressure blowing crank seal :link:

@Jones95 , mate read the above then get your mechanic to check for the crank free play.

Ok so i noticed something new yesterday, my partner was driving and I noticed as we were going up a big hill, in 5th gear at around 100km/h, the vibration started just below 2000rpm as normal, but I was watching the speedo and it was jumping up and down by 10-20km/h, just like a tacho would if the clutch was slipping.

I did a quick search and found that in most cars the speed is measured off the drive shaft? is this the same for the 2011 i30 crdi? It could point to a problem there....

Interesting!  :goodjob2:
Almost there,  :evil:  the speed sensor will be at the back of an old gearbox or more likely on the diff. The VSS on the i30 is on the transmission/gearbox given that it also functions as a differential. (top, far Left from memory)

No direct relationship to the vibration comes to mind. I would be looking for a poor a electrical connection that is being physically shaken by the vibes.

 The connector may have been left loose when the 'A team' were doing the usual clutch change.

Thank you for getting back to me with that!

Iím sure I (and others) have your head melted with all of this and I just wish it was something simple. Iíll admit I have no technical knowledge regarding what youíve said but Iíll show my mechanic and hopefully get this resolved once and for all.

Thanks to everybody trying to help!

Devils Advocate, Left field comment;

Has anyone checked out the driveshafts on this in particular the inner joints. Most susceptible the longest shaft. There may be evidence of grease leaving the boot under the clamp.

These wear out and the tripod goes off centre then due to the excess clearance causing vibration. Depending on how bad it is they can be quite bad and will transmit through the chassis, generally only at certain combinations of RPM , gears , load and speed. I found it more on the taller gears. maybe 3 up

No oops mate. :disapp:
You are ignoring your research principle.
Clutch and flywheel were changed. Which one was at fault?

Well, an update!

I see the noise has been fixed for a member, Iím happy for you!

The reason I havenít made an update is simply I havenít had anything new until this point. Got the car back a couple weeks ago, itís still making the noise but; I went to the garage, got the invoice and this is what has been fixed:

New Clutch Kit
New Gearbox
Wheel Bearing (FRHS)
Turbo checked
Tyre rotation
Discs/ Brakes replaced.
A/C Pipes were fixed (didnít know there was an issue there!)
Full Service
Flywheel checked
Exhaust checked for vibration

So, all in all, I practically have a new car. The noise is still there. I am not happy about that, but I will live with it. The garage (remember it was a used car dealer) bought me a nationwide warranty which covers parts/ labor for 12 months, should something go wrong. They also gave me a full tank of diesel so 👍.

If something goes wrong, I shall definitely update. But aside from the noise, the car is driving better than ever and I am thoroughly enjoying ownership. Thank you all for the help.

Thanks for the update. They have certainly gone above and beyond. Still frustrating though.  :crazy1:
