A faulty ECU can cause all sorts of problems - from a persistent engine management light to a car that won't start at all. A main dealer will almost always recommend a brand new replacement unit, which can cost anywhere from £500 to over £2,000 before fitting and coding. In many cases, the existing unit can be repaired for a fraction of that cost.
At Doyen Auto Services in Rutherglen, we have the diagnostic equipment and expertise to identify exactly what's gone wrong with your ECU. Common faults include blown capacitors, damaged driver circuits, water ingress corrosion, and corrupted software. We can repair the physical damage and reprogram the unit so it works like new.
ECU repair is especially valuable for older or specialist vehicles where replacement units are expensive or hard to source. We've repaired units for everything from everyday commuter cars to performance vehicles and classic cars across the Glasgow area.
Case-by-case pricing. The figures below are starting “from” prices - your final quote depends on your vehicle's make, model, and condition.
