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
