Sinspeed, automotive electronics remanufacturing in Epsom

Sinspeed is a UK remanufacturer of car electronic modules that works on a mail-in basis. Customers post the failed unit to the workshop in Epsom, Surrey; the company diagnoses it, repairs it at circuit level, tests it under simulated driving conditions and returns the same unit, still coded to the vehicle. The vehicle itself stays with its owner throughout the process.

The company was founded in 2007 and describes itself as one of the fastest growing automotive parts remanufacturers, with a team of electronic and hydraulic engineers. Its stated aim is to offer an affordable alternative to buying new replacement parts.

Modules handled

The catalogue covers a broad range of electronic and hydraulic components, organised by category and by vehicle brand. Among the units listed are:

• ABS pumps
• Air conditioning compressors
• Airbag ECUs
• Body control modules
• Climate control modules
• Clutch actuators
• Comfort modules
• Diesel pumps
• Differential ECUs
• Electric power steering
• Gear actuators and gear selectors
• Instrument clusters and MFD units
• Throttle bodies
• Transmission control modules
• Turbo actuators and turbochargers

Beyond repairs, the site lists ECU remapping, DPF installations and removals, EGR removals, immobiliser repair, lighting and sat-nav work, and headlight control modules.

Brand coverage

The repair catalogue is indexed by manufacturer, with dedicated pages for ABS and instrument cluster work across a long list of marques. These include Alfa Romeo, Audi, Bentley, BMW, Cadillac, Chevrolet, Chrysler, Citroen, Dacia, Daihatsu, Dodge, Ducati, Ferrari, Fiat, Ford, Honda, Hyundai, Iveco, Jaguar, Jeep, Kia, Lancia, Land Rover, LDV, Lexus, Lincoln, Lotus, Maserati, Mazda, Mercedes-Benz, MG, Mini, Mitsubishi, Nissan, Peugeot, Porsche, Renault, Rover, Saab, Seat, Skoda, Smart, Ssangyong, Subaru, Suzuki, Toyota, Vauxhall/Opel, Volkswagen, Volvo and Wiesmann. A vehicle search tool lets users filter by brand, model and year, with model years ranging from 1976 to 2026.

Gearbox and transmission work

A significant part of the catalogue is devoted to transmission components. The company rebuilds valve bodies, mechatronic units and TCMs on the bench, and covers the Ford PowerShift family in both its dry DPS6 and wet 6DCT450/6DCT450 MPS6 forms. It also rebuilds the conductor plate of the Mercedes 722.9 7G-Tronic VGS, keeping the programming intact, and repairs the PowerShift DPS6 clutch actuator motors, which are bench-tested under load before being returned.

Diagnostics and documented faults

The site publishes technical write-ups on specific faults, such as the Audi C10AD29 electric power steering code, Ford Transit Mk8 BCM faults, Vauxhall IntelliLink screen and sat-nav failures, Audi MMI navigation, screen and sound problems, DRL and adaptive AFS headlight faults, and the differences between Ford's wet and dry PowerShift gearboxes. These articles describe symptoms, causes and which module fails, and sit alongside the corresponding repair service.

Warranty and process

The company states that almost all of its repairs carry a lifetime warranty, and that turbocharger rebuilds come with a two-year warranty and instrument cluster repairs with a lifetime warranty. The workflow is consistent across the catalogue: the customer posts the faulty unit, the workshop diagnoses and repairs it at component level, tests it under simulated driving conditions and returns it still coded to the vehicle.
