Hyundai i30 Relays
Relays to suit the Hyundai i30, cross-referenced against OEM specification and dispatched countrywide
What Are Hyundai i30 Relays?
A relay lets a small signal from the ECU or ignition switch a much larger current — fuel pump, cooling fan, starter, headlamps. The Hyundai-specific catch is that the relay list is not the same across a model: the CRDi diesels carry a glow-plug relay that no Kappa or Gamma petrol car has, and air-conditioned derivatives add relays that the base cars simply do not fit. That is why a relay layout for a 1.4 petrol i20 tells you very little about a 1.6 CRDi. Work off the diagram on the underside of your own fuse-box lid, and send us the engine code with the enquiry.
Signs You Need New Relays
Before you order relays for a i30
Ordering relays for a i30 starts with the generation: FD, GD and PD.N Line and standard derivatives differ in brakes, suspension and bumper mouldings — the badge on the boot changes the parts list, not just the trim.
Engine families fitted to the SA-market i30:
Coded and paired components — immobiliser-linked and body-control items in particular — will not simply plug in on a Hyundai. Some need matching to the car before they will function.
Send us the VIN, and the fault code if the car has been scanned with your enquiry and we will confirm the correct relays against your car before anything is dispatched.
In South Africa the i30 is mostly bought by drivers who wanted a more solid-feeling hatch, and now aging into the independent aftermarket where the Kia cross-reference becomes genuinely useful. That is the wear pattern we stock and source against.
Hyundai i30 Relays — Questions We Get Asked
Will relays from another i30 fit mine?
Not automatically. The i30 sold in South Africa as FD, GD and PD, and N Line and standard derivatives differ in brakes, suspension and bumper mouldings — the badge on the boot changes the parts list, not just the trim. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
Which engines did the South African i30 come with?
SA-market cars ran Beta II 2.0 (FD), Nu 1.8 (GD), 1.4 T-GDi (PD N Line), U-line 1.6 CRDi on selected derivatives. The code stamped on the block is what we work from — the badge on the boot is not reliable on its own.
Does my Hyundai have a glow plug relay?
Only if it is a CRDi diesel. That is the single biggest difference between the relay layout on a diesel and a petrol Hyundai — the Kappa and Gamma petrol cars have no glow plugs and therefore no glow plug relay at all. If a diesel is hard to start cold, that relay is the first place to look.
What does a failing relay do on a Hyundai?
The pattern we see most is a no-start with the fuel pump silent, a loud click from the fuse box, cooling fans stuck permanently on or off, or an electrical fault that comes and goes with no obvious trigger. Intermittent is the word that most often means relay.
What does a Hyundai relay cost to replace?

The starter relay clicks but the car will not crank. Is the relay dead?
Not necessarily, and this is worth checking before you buy anything. A click without crank means the relay is energising but not passing enough current to the starter solenoid — and a tired battery mimics that exactly. We check battery voltage under load and the earth straps before condemning the relay.
How do I find and test a relay on my Hyundai?
Work off the diagram on the underside of your own fuse-box lid rather than a diagram from the internet, because air-conditioned and non-air-conditioned derivatives fit different relays and facelift cars occasionally moved a slot. To test, swap it with an identical relay of the same rating from a non-critical circuit such as the horn and see whether the fault follows.
