Book a Workshop Slot →Close Enough to Drive In — Specialist Enough to Fix What Others Can't
Stevenage sits about 25 miles from our Enfield workshop — close enough to make a drive-in booking a practical option for most customers. You arrive, one of our specialists takes the car, diagnoses the ECU fault fully, carries out the repair start to finish and returns the vehicle to you the same day.
Prefer the postal route? That works too — remove the ECU, post it tracked and we'll have it back in 3–5 working days. Either way, you're dealing with specialists who fix ECU faults at component level, not workshops that simply swap units.
Persistent Engine Warning Light
Codes that keep returning after being cleared often indicate ECU damage rather than a sensor fault. We check the ECU itself as part of every diagnosis.
Car Won't Start — No ECU Communication
A dead ECU that doesn't respond to diagnostics usually has an internal power supply failure. Repairable in most cases without needing a replacement unit.
Intermittent Cutting Out
Random stalling or cut-outs with inconsistent fault codes are a classic sign of dry solder joint or track damage on the ECU board.
Post-Flood or Water Damage
Moisture on an ECU board causes corrosion and short circuits. We clean, repair and restore water-damaged units where others won't attempt it.

Arrive at the agreed time, hand the vehicle over to your assigned specialist and we'll keep you updated throughout the repair. The vast majority of ECU faults are diagnosed and fixed in a single visit — you leave with a working car and a written repair report.
We cover all makes and models — petrol, diesel, hybrid — including cars, vans and light commercials.

Quick Questions
Do I need to book in advance for a drive-in appointment?
Yes — we work by appointment to ensure your specialist is dedicated to your car from arrival. Call or message to book and we'll confirm the address.
Will the ECU need recoding after repair?
In most cases no — we repair your original unit so it stays matched to your immobiliser. We'll tell you if your repair is an exception.
