Relays for Hyundai i10

What Are Hyundai i10 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

Engine cranks but won't start (fuel pump relay)
Audible click from fuse box with no starter action
Diesel hard to start when cold (glow plug relay)
Cooling fan runs constantly or not at all
Dashboard warning lights flicker intermittently
Relay feels hot or shows burnt pins when pulled

i10 generations and relays — the short version

Does one relays listing cover every i10?

No. i10 owners are usually surprised by how much turns on the generation code — PA, then the Grand i10 BA, then AI3 all sold here.The original PA i10 and the later Grand i10 are separate platforms with separate parts catalogues — "i10" on its own is not enough to order from.

Which engine is in my i10?

SA-market cars were sold with Epsilon 1.1 (PA), Kappa 1.25 (Grand i10) and Kappa 1.2 (AI3). The code stamped on the block settles it — the badge on the boot does not.

What do you need from me to quote relays?

The VIN, and the fault code if the car has been scanned. 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.

In South Africa the i10 is mostly first cars, driving-school fleets and short-hop city work, so components see far more cold starts per thousand kilometres than the odometer suggests. That is the wear pattern we stock and source against.

Before You Order i10 Relays

Will relays from another i10 fit mine?

Not automatically. The i10 sold in South Africa as PA, then the Grand i10 BA, then AI3, and the original PA i10 and the later Grand i10 are separate platforms with separate parts catalogues — "i10" on its own is not enough to order from. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.

How do you check relays actually fits a i10?

We work backwards from the VIN: generation first, then engine family, then whether the car is pre- or post-facelift within that generation. On the i10 specifically, the original PA i10 and the later Grand i10 are separate platforms with separate parts catalogues — "i10" on its own is not enough to order from.

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.

Let us confirm the relays before you buy

Photos of the old part and your VIN are usually all we need. We confirm the relays against your i10 before quoting, not after.
