I've got a bit of a concern with the i30. Just marked 32k and for the last couple of weeks the car, when idling, almost feels like it's shivering. Nothing major but I can notice it when stopped at lights etc... also seems to be worse when the AC is on. Turning the AC off instantly cuts the shiver in half.
Moved from Wagga to Sydney for study so the cars now being exposed to long idles waiting at lights and stuck in traffic. Could it be the car "adjusting" to city life?
I've been reading few similar topics and people suggest a fuel additive to help clean the engine. The cars never had anything but 98 Premium in it whixh I understand already has cleaners in it so will a 3rd party additive help much?
Thanks guys!!

I'll take notice of the rpm when it happens next. I drove to work today but it only takes about 5 minutes to get there so the engine might have been warm enough for the issue to fully show. Usally tho the car idles at around 500rpm, turning he ac on and off makes it go to maybe 510rpm when on?? The needle only moves a tiny bit.
The car did have its 30k service about 3 months ago but everything seemed fine after that.

I too get a shudder especially felt through my gear lever when the AC is on. Could your idling be too low? It feels to me like there is a 'sweet spot' where there are no vibrations at all, but anything lower or higher by a handful of rpm causes it to shudder a bit

Yep, that was my thinking too... :cool:

My OBD reader (a cheap one) doesn't tell me if the rev counter is correct but the gauge seems to indicate that my 1.4 petrol is about 1100 when cold and drops to 740 or so when warmed up. The tick-over speed doesn't seem excessive to me, similar to all my previous cars.

I don't get no judders. :)

Over the obd2 I can see my Idling speed always sits at 780 +-10(max)
Exactly what the needle says.

Never drove a petrol with rpm-meter..

If you increase the revs to 900-1000 rpm does it disappear or just reduce a bit?
If it disappears it probably is just excessively low idle speed.

I'll take note of that next time Gof and report back, thanks!! :goodjob:

Chased the same issue with another if my cars until the plug eventually fell off and then the issue was clear.
While the car ran, the injector pulse was weak as it was jumping a gap.
If it has been an issue since service ring the dealership that did it and tell them you want it sorted.
