Hyundai i30 ECU/PCM
Whether your i30 is an early or late build, we match the ecu/pcm to your derivative rather than to the badge
What Are Hyundai i30 ECU/PCM?
The ECU or PCM is the engine's brain — managing injection, timing, turbo boost and emissions on your Hyundai. Getz and i20 1.6 petrol ECUs sit under the bonnet where rainwater ingress kills them. I20 models use a stouter box but throw signature P0003/P0245 codes when fuel-pressure circuits fail.
Signs You Need New ECU/PCM
Getting the right ecu/pcm for your i30 first time
Does one ecu/pcm listing cover every i30?
No. Sold here across FD, GD and PD, the i30 is not one car for parts purposes — it is several.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.
Which engine is in my i30?
SA-market cars were sold with Beta II 2.0 (FD), Nu 1.8 (GD), 1.4 T-GDi (PD N Line) and U-line 1.6 CRDi on selected derivatives. The code stamped on the block settles it — the badge on the boot does not.
What do you need from me to quote ecu/pcm?
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 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.
Before You Order i30 ECU/PCM
Will ecu/pcm 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.
How do you check ecu/pcm actually fits a i30?
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 i30 specifically, 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.
How much does a Hyundai ECU cost in South Africa?
Real SA pricing: Hyundai i20 1.6 MPi ECU around R4,500 and 1.6 T-GDi around R5,500 (used, VIN-specific). Repair estimates sit near R3,167. Our supplier network stocks used units across most models.
What are the symptoms of a faulty Hyundai ECU?
No-start, erratic running, multiple scattered warning lights after wet weather and comms errors on diagnostic scan. On i20s the P0003 and P0245 fuel-pressure codes point to ECU. Water damage in Getz/i20 ECUs leaves visible green corrosion in the plug.
Can a Hyundai ECU be repaired or must it be replaced?
Many can be repaired — SA specialists rebuild i20 MPi, Accent and Tucson T-GDi ECUs for around R3,167, keeping your original coding. Severe water damage with corroded circuit tracks usually means replacement plus VIN coding.
Does a replacement Hyundai ECU need to be programmed?
Yes — new and used ECUs must be VIN-matched and often coded to your BCM (body control module), immobiliser and key. SA Hyundai specialists handle this in-house. We match used ECUs by exact part number to minimise coding headaches.
What causes Hyundai ECU water damage?
The Getz and i20 1.6 MPi ECU sits in a tray behind the air-box where scuttle drains can block and flood it. Blocked pollen-filter drains and leaking windscreen seals are the usual culprits. Clean scuttle drains yearly — it's a free, Hyundai-saving service.

Let us confirm the ecu/pcm before you buy
Photos of the old part and your VIN are usually all we need. We confirm the ecu/pcm against your i30 before quoting, not after.
