2011 i30, 1.6 CRDi, Clutch/ Harsh Vibration Issue
« January 27, 2019, 07:34:53 »
Hi all,

New to this forum so hoping Iím in the right place! Iíve read many posts regarding the clutch but still would like to post my own as thereís a couple of additional issues that Iím unsure if are clutch related

Issues

- Must push clutch hard down to the floor to change gears. Lift a few mm and it bites.

- Crunching going into reverse 9/10 times. 1st is as hard to get into. The rest of the gears seem to engage/ disengage fine other times but when coming down the gears there can be difficulty, regardless of the gear/ speed

- a slight rattle when accelerating (doesnít matter of speed. Can be on take off or when accelerating through the gears). This rattle type sound is coming from around the left passenger side of the car.

- from 3rd gear on, if I hard accelerate at about 1800rpm thereís a loud shudder/growl/ vibration throughout the car. This stops at about 2000rpm. The previous rattle seems to lead up to this.

Iím not sure if the last two points, or all are linked. I asked my mechanic and he reckons itís all to do with the clutch. He thinks the rattle could be the springs and the growl could be the pressure plates or something but heís never worked on a Hyundai so canít be sure!

The car - 2011, 1.6 CRDI, 90k miles on the clock. I just bought the car last week and stupidly didnít notice these issues. Dealer purchase though.

Apologies for the long post! Iíve tried to be as clear as I can be and Iím not massively mechanically minded so Iím hoping someone could help! Iím bringing the car back up during the week but the clutch isnít covered so hoping it could be replaced under good-will as Iíve done about 100miles since ownership.

Thank you.

If you just got it from the dealer(Hyundai ?) and it has warranty the low bite point is highly likely due to a faulty clutch damper valve.

Seems to be a very common issue. It has been highlighted in the forum and a few of us have deleted the damper valve with a blanking plug.

Immediately fixed all my issues which just so happens to match your symptoms. Mine got to the point the clutch was permanently dragging and had to slam it into reverse  as the teeth were rotating.

You'd have to confirm the part number

41690-2H900

The damper does soften th erelease so deleted you may have to re-calibrate the left leg  :goodjob2:

Hi, thank you so much!

It wasnít a Hyundai dealer, but a reputable used car dealer. Theyíre registered and so on.

I was reading something about the damper valve yesterday but again without being mechanically minded I was at a loss! Iím planning on bringing it up to them today if possible. Otherwise, Iíll visit my mechanic and explain what you have said/ linked!

Regarding the rattle/ harsh vibrations around 1800rpm, was it the damper causing these issues for you also? As so far Iíve read engine mounts, Slave/ Master cylinders, clutch/ transmission fluid (which Iíve checked and is fine. No leaks at the cylinder either) and Iíve read a few other points too.

Iíll go up today and hopefully the dealers mechanic will be spot on and itíll be hassle free regarding them doing the work!

Thanks so much again, much appreciated!

Sorry, I should clarify. Only the clutch issue. Can't comment on the rattle. Diesel is not always the most refined but , may have a failed mount, seized clutch pulley on the alternator can cause horrendous noise, worn engine cover mountings if that is loose can resonate but impossible to know in a forum what you're hearing.

Did you find a solution regarding the the rattle / noise at 1800 rpm. I got an 2009 1.6 crdi, with the exact same problem?

Hi,

Apologies for only replying now! I still havenít got to the bottom of the issue! (Check my most recent post) but really, you are?!! Iíve been searching and searching and youíre the only person that seems to be having the issue as I am.

It was at 1800-2000rpm, the garage changed the pressure plate and it now starts at 2000-2200rpm! Itís infuriating.. the garage has stripped the car, checked the turbo, engine, entire exhaust system, removed the dpf to check its condition, ran diagnostics, and still.. nothing.

Have you had any luck?!

Did they check flywheel? It maybe not completely flat and the runaway is off the specs.

Apparently ďi30ís donít have flywheelsĒ.

I donít know as Iíve seen multiple threads debating this topic in particular on different sites.. from reading previously I thought it may have been a flywheel issue. I will ring their mechanic directly tomorrow.

Thank you.

All i30's have flywheels. The discussions you are referring to are regarding whether or not they have regular flywheels or dual mass flywheels. Generally they have regular flywheels although apparently Dual clutch models may have dual mass versions.

Edit: Phew, I beat Gary to the draw.. I think his answer might have been a bit more curt and sarcastic..  :rofl:

   :utterrubbish:

Mate you have been given well considered advice and directions to this club's threads on the subject  , but here we are discussing your vibration after you re-posted your problem.

I have personally put in a lot of time for you, hoping that you would avoid the expense and frustration when your mechanic tries to reinvent the wheel...and I didn't mean the flywheel. :crazy1:

Now you introduce this utter shit that has come from some unqualified dropkick.

It just muddies the water for the next reader.  :head_knock:

Of course the bloody car has a flywheel! What do you think the clutch is bolted to?  :wacko:
 And why is the clutch mentioned in all OUR posts that you DID NO BOTHER to read?

Only just Wyatt.  ;)

Ive read some doozies before, but this one takes the cake.

Edit: Clearly, we are talking about the manual gearbox i30s with vibration.  The Auto transmission i30 is not part of the discussion.
 All makes of automatic cars have a flexi-plate that secures the torque converter. If it has starter ring gear attached, it is often called a flywheel.
