Hyundai i20 ECU/PCM
ECU/PCM for the Hyundai i20 — new, used and aftermarket stock, quoted once we know which i20 you are running. Find quality Hyundai i20 salvage yard at our facility.
What Are Hyundai i20 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
What a parts desk needs to know about your i20
What changes across the range
On the i20, PB, then GB, then the current BC3 are all in circulation locally, and they do not share one parts list.
The PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it.
Worth knowing: the i20shares its Kappa and Gamma engine families with the Kia Rio.
What we check on ecu/pcm
- •The generation code, because i20 parts lists split on it
- •The engine family — this i20 was sold with Kappa 1.2, Gamma 1.4 and Kappa 1.0 T-GDi (N Line)
- •The VIN, and the fault code if the car has been scanned
- •Whether the car is pre- or post-facelift within its generation
In South Africa the i20 is mostly a high-mileage commuter hatch that spends its life in stop-start city traffic, which is why wear items move faster on an i20 than on almost anything else Hyundai sells here. That is the wear pattern we stock and source against.
Hyundai i20 ECU/PCM FAQs
Will ecu/pcm from another i20 fit mine?
Not automatically. The i20 sold in South Africa as PB, then GB, then the current BC3, and the PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
What should I send you when asking about i20 ecu/pcm?
The VIN is the single most useful thing — a photo of the plate is fine. Failing that, the generation code and the engine code off the block. The i20 ran as PB, then GB, then the current BC3, so the generation is what narrows the search.
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.
