What Are Peugeot 508 ECU/PCM?
The ECU or PCM is the engine's brain — managing injection, timing, turbo boost and emissions on your Peugeot. 206 and 207 1.6 petrol ECUs sit under the bonnet where rainwater ingress kills them. 208 models use a stouter box but throw signature P0003/P0245 codes when fuel-pressure circuits fail.

Common Questions About Peugeot 508 ECU/PCM
How much does a Peugeot ECU cost in South Africa?
Real SA pricing: Peugeot 207 1.6 VTi ECU around R4,500 and 1.6 THP 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 Peugeot ECU?
No-start, erratic running, multiple scattered warning lights after wet weather, and comms errors on diagnostic scan. On 208s the P0003 and P0245 fuel-pressure codes point to ECU. Water damage in 206/207 ECUs leaves visible green corrosion in the plug.
Can a Peugeot ECU be repaired or must it be replaced?
Many can be repaired — SA specialists rebuild 207 VTi, 207 THP and 208 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 Peugeot ECU need to be programmed?
Yes — new and used ECUs must be VIN-matched and often coded to your BSI, immobiliser and key. SA Peugeot specialists handle this in-house. We match used ECUs by exact part number to minimise coding headaches.
What causes Peugeot ECU water damage?
The 206 and 207 1.6 VTi 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, Peugeot-saving service.
