What you are looking at

No photograph available

We do not hold a verified photograph of the Clutch yet. We would rather show none than show a picture of a different part.

What goes wrong

PD-generation Hyundai i30 models with the 7-speed dry dual-clutch transmission share the documented judder and hesitation pattern found across Hyundai and Kia's 7DCT range. The dry clutch design is susceptible to micro-slip vibration at very low engagement speeds, felt as shudder during gentle take-offs. Hyundai issued TCU calibration updates for the i30 PD in several markets but clutch pack wear on high-mileage urban vehicles requires mechanical repair regardless of software state. This is one of the most frequently raised concerns by NZ and AU i30 PD owners.

What you would notice

Vibration or shudder through the car body when pulling away gently from a stop
Hesitation before first gear engagement from rest
Clunking or jerkiness at low speed in stop-start traffic
Difficulty holding position smoothly on slight inclines

How to check it

Where to look. 7DCT gearbox and dry clutch assembly, front of drivetrain

Dedicated low-speed test in traffic: approach a stop then gently pull away multiple times. Test on a gentle incline. Repeatable shudder felt through the seat and floor is characteristic of clutch wear. Check with Hyundai dealer for any TCU update applied to this VIN.

Parts involved: Clutch.

What it costs to put right

$300 to $4,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the transmission software ever been updated at a Hyundai dealer?”
“Does the car shudder when pulling away from traffic lights?”
“Has any transmission or clutch work been performed?”
