Peugeot 207 & 206 engine ECU with common water damage

Peugeot 206 & 207 engine ECU water ingress

This water damaged ECU is a very common failure for Peugeot 206 & 207 vehicles built between 2005 and 2011, the common issue is coolant contamination into the wiring harness that travels via ‘capillary action’ up to the plug of the ECU, once the water from the coolant system reaches the ECU it causes the ECU terminals to corrode causing open circuits for various sensors and actuators, this results in host of running problems for the engine.

The most common issues seen are engine misfires, engine not revving properly due to throttle position faults, engine won’t start or cuts out, normally the Anti-pollution light will also be illuminated on the instrument cluster.

When diagnosing, the fault using a diagnostic scanner there will usually be fault codes stored for the throttle position sensors, injector circuits, coolant/air temperature sensor faults or O2 sensor faults. Often the fault is initially misdiagnosed since the fault codes are blaming other sensors on the car, which can lead to replacing these sensors unnecessarily before identifying that the ECU is the cause of the fault. We are able fully rebuild your water damaged ECU and supply an unlimited mileage lifetime warranty*

Test and rebuild:

Our bespoke HIL test rigs (Hardware In-the-Loop) allow us to run the ECU as though it where on a vehicle. Testing under real-world driving conditions and load, before and after the rebuild, ensures that the ECU will outlast the vehicle it is fitted back onto. Using only the highest rated components we will rebuild your ECU within 2-3 working days.

 

Programming:

There is no need for any programming once you receive your rebuilt ECU back, just plug in and away you go.
