Independent BMW Specialist in Harrow — Expert Servicing, Diagnostics & Repairs
A Small one man Workshop with Main Dealer Knowledge
Welcome to EFG Automotive – Independent BMW Specialists
Your local independent BMW specialist in Harrow. Run by a single experienced BMW technician with dealer-level tools and genuine expertise, I offer a personal, high-quality service covering everything from routine maintenance to complex electrical and mechanical repairs.
As a one-man specialist workshop, all work is carried out personally — ensuring dealer-level standards, attention to detail, and honest advice every time.
I combine factory-level BMW knowledge with a personal, appointment-only service. My small Harrow workshop is equipped with official BMW diagnostic software, programming tools, and precision equipment — allowing me to perform everything from approved servicing and software updates to advanced diagnostics and full engine rebuilds.
Because I work alone and take on each car personally, I operate strictly by appointment only. Please call before visiting, as the workshop is often fully booked and space is limited.
Servicing starts from £150 + VAT
Diagnostic investigation from £120 + VAT

BMW OEM RETROFITS & FEATURE UPGRADES
Full Screen Apple Carplay
We offer lifetime Apple CarPlay activation with full-screen functionality, giving you seamless integration for navigation, music, and hands-free communication. Unlike BMW’s official solution, which was originally offered on a subscription basis and often restricted to a split-screen display, our activation unlocks the complete CarPlay experience permanently. With genuine BMW software activation, you enjoy the exact same functionality as factory-installed CarPlay – but without ongoing costs or limitations.

We provide full BMW servicing using only genuine OEM or upgraded parts and approved oils, ensuring your car is maintained to the highest standards. We update your BMW’s online and digital service history, keeping records exactly as the main dealer would. Every service also includes a detailed video health check, giving you complete transparency and peace of mind about the condition of your vehicle.
Heated Steering Wheel Retrofit
We offer professional BMW heated steering wheel retrofits for models including the BMW G30 5 Series, carried out using genuine BMW parts and specialist coding. Our retrofit service integrates seamlessly with your car’s original systems, ensuring full factory functionality and an OEM+ finish. Adding a heated steering wheel not only enhances your BMW’s specification but also keeps your vehicle aligned with factory upgrade standards.
