Uncover Hidden Issues With Precision Diagnostics

The vehicles of today are powered by sophisticated electronics and heavily integrated systems. When something feels off, or a warning light appears, it’s crucial to have a professional assess what’s really occurring under the hood. Our specialised diagnostic services go beyond basic scan tools, identifying root causes swiftly and accurately to help you avoid costly repairs down the track.

What Our Valued Clients Have To Say

Isaac B

Fantastic, knowledgeable, informative, team at GMW. Had my 3series with them for some work and I can’t think of a single negative thing to say. Kept me in the loop at all times and made sure that the work they did is to the highest of quality and satisfaction. Any questions I had were answered with confidence and reassurance. Can only recommend for any BMW OR MINI work you need.

Jeremiah O

Great service from the mobile servicing team at GMW. Josh identified the problem and sourced all the parts to have the car running again by the end of the day. Excellent service and great communication!

William G

True enthusiasts and the coolest guys who know everything about BMW machines. After ‘shopping around’ other mech shops to try and fix my fuel delivery issue, Douglas and team at German Motor Werks identified and fixed the issue with confidence, and that was extremely reassuring. I wouldn’t take my BMW to anywhere else any longer! Cheers

Nick M

Just had the third service with GMW on our 2018 M4 Competition. These guys are the best. No birds, just great service and sensible advice, and excellent value. Highly recommended.

James M

First time taking my BMW in and I couldn’t have been happier with the work done. Douglas and the team provided an in-depth explanation, including photos of every step of the repair that was completed, and was more than happy to take the time to explain exactly why the car had the issue. Not only this but GMW is the most professional and affordable specialist that I have gone to. I will absolutely be returning to GMW for any future work that is needed and couldn’t recommend GMW more. Thank you Douglas and the rest of the team for looking after my vehicle.

Vikki S

I cannot fault the work Josh (GMW) has done on my Mini Cooper S. This is my seventh mini and I have had some disappointing experiences with various mechanics over the years. I have found Josh to be very helpful, competent and knowledgable about minis and he explains things when I have any queries. Plus, It is very convenient to have him come to my home. I would not hesitate to recommend him to anyone with a Mini or BMW and wish I had found him before.

Sally M

Douglas and the team are excellent at what they do. Their treatment of me and my car leaves no doubt. Always up front and honest, and provide great advice. Highly recommend if you love your car and want the best care for it!
