Book an ECU repair

The Engine Control Unit (ECU) is the brain of your vehicle and works to keep it running smoothly. If it's acting up, it can mean poor performance, increased fuel consumption, or trouble starting your car.

Any work done will meet the high standards set by the RAC.
We’re friendly, straightforward and jargon-free

Book a diagnostic

A mechanic will check your car for faults and talk you through any repairs you might need. There are various ways to check for faults, which could include a physical examination or plugging in to check your car’s onboard engine management system.

We’ll look for any mechanical or electrical problems. If we need to, we’ll also check your car’s onboard engine management system. Depending on your car and issue, this will usually include: – Engine – Power steering – Brakes – Transmission – Exhaust system – Fuel injection system – Cooling system and air flow – Sensors
