David Keller

Technical Specialist

David does all of his own BMW maintenance — brake jobs, cooling system refreshes, VANOS solenoids, valve cover gaskets, the lot. His guides are written from the garage floor, with the actual torque specs, the tools that fit in the space BMW gave you, and honest notes on which jobs are truly DIY-friendly and which ones belong at an independent specialist. If a guide says “30 minutes,” it’s because he timed it.

What David covers

DIY maintenance, troubleshooting, warning lights and error codes.
