Modern cars are more like computers on wheels and central to that is the ECU. If the engine is the heart of the car, the Electronic Control Unit or ECU is its brain. Your car may develop a fault that you think is mechanical but actually the real culprit could be the electronics, caused by a malfunctioning ECU or one of its sensors.
The ECU is now such a crucial and integral part of our cars that I think it’s worth understanding exactly what it does.
Breaking down could become a thing of the past with telematics
Technology that only a few years ago would have seemed like a dream is now coming to a car near you. The latest can predict if your car is going to break down. It’s estimated it could save British drivers 38,000 hours waiting for roadside rescue with their conked-out car.

This enables it to record changes such as the battery failing to hold its charge before the driver would ordinarily notice them. If it does see changes, Alert Me reports it to Green Flag over the mobile phone network. Green Flag then notifies the driver via a smartphone app. Continue reading →
Sensible drivers have breakdown cover and ring to be rescued

Obviously cars are very complex machines with a lot of different components working together. At Green Flag we’re proud of our ability to get members’ cars going again when we attend breakdowns. And last year we helped out nearly 200,000 people. Here are the most popular reasons for calling out our technicians in 2014. Continue reading →
