Independent BMW specialist
Independent BMW Specialist in Sunbury-on-Thames
The Factory services and repairs all makes, but BMW is a major area of specialist experience.
Many BMW owners want main-dealer technical capability without the main-dealer experience. That’s exactly where The Factory sits: a Master Technician with BMW training leads the workshop, and we use BMW ISTA — BMW’s own diagnostic system — alongside Bosch, Autel and Snap-on equipment.
From Condition Based Servicing with digital service history updates to timing chains, ZF gearbox servicing, air suspension and electrical diagnosis, we handle the work BMWs typically need — petrol, diesel, hybrid and electric.
You’ll be shown what we find, with photos or video where useful, and nothing additional is done without your authorisation.
