About Bence AEC
At Bence AEC Ltd, we specialise in the work most garages can’t do — or won’t attempt. Vehicle electronics, complex diagnostics, module coding, and software-level faults are our core expertise, not a sideline.
Founded by a master technician with over 15 years’ experience at BMW, Audi, and Mercedes main dealers — plus specialist vehicle builds for the emergency services — we bring genuine dealer-level knowledge and manufacturer-grade diagnostic tools to every job.
From persistent warning lights and parasitic battery drains to ECU coding and feature activation, we trace the actual fault and fix it properly the first time.
No guesswork.
No parts-swapping.
No passing you between departments.
Just a trained specialist who finds the fault, explains it clearly, and repairs it right.
Our Services
Electrical faults are the number one reason vehicles get misdiagnosed — costing owners hundreds in unnecessary parts. With manufacturer-grade scan tools and over 15 years’ main-dealer experience, we trace faults to the component level. We diagnose and repair:
- Warning lights and fault codes
- Battery drain and charging issues
- Alternator and starter motor problems
- Wiring and electrical component faults
Vehicle software is becoming as important as the engine itself. We carry out coding and programming work that most independent garages simply cannot offer — using the same tools and processes as franchised dealers:
- Online coding and module programming via manufacturer portals (BMW, VAG, Mercedes, and more)
- ECU and control module software
- Hidden feature activation — unlocking factory-fitted options such as digital speedo, needle sweep, mirror dip, and comfort settings (vehicle-dependent)
- Module replacement, virgin coding, SCN coding, and post-repair adaptation resets
Transform your in-car experience with a professionally fitted Apple CarPlay retrofit. We use OEM-grade modules that integrate seamlessly with your vehicle’s existing head unit — no bodged wiring, no aftermarket head units, no voided warranties.
- Factory-style integration that looks and feels like it came with the car — using your existing screen and controls
- Clean, hidden wiring with no visible modifications to your dashboard or trim
- Wide compatibility including BMW, Mercedes, Audi, VW, Land Rover, Porsche, and more — call us to check your vehicle
Alongside our electrical specialism, we provide thorough mechanical work carried out to main-dealer standards — with the personal service of an independent:
- Full interim and major servicing using OE-quality parts — maintaining your manufacturer warranty
- Comprehensive battery health testing with professional conductance analysers, plus supply and fitment of quality replacements
- Alternator output and ripple testing — identifying failing diodes and voltage regulators before they leave you stranded
- Pre-MOT inspections and MOT failure repairs — brakes, suspension, lighting, emissions, and more
- Specialist in modern vehicle electronics
- Advanced diagnostic equipment
- Honest pricing and clear explanations
- Quality workmanship you can rely on
- Friendly, professional service
Your vehicle receives the same level of care and attention it would get at a franchised dealer — with none of the markup.
