Notes
REBUILDING A CHEAP BMW M5 COMPETITION | PT 1 takes viewers through the early, high-stakes phase of buying and attempting to rebuild a crashed 2019 BMW M5 Competition. The host outlines two possible outcomes from the outset: either the car proves to be a great deal or a money pit, and he dives into diagnosing why the previous mechanic stopped the repair. Early on, the video covers initial electrical issues, including a faulty pyro fuse, and demonstrates a provisional fix by bridging electrical connections and swapping in a battery while awaiting a proper fuse. The narrator then details the plan to extract the engine to inspect for hidden damage, explaining the potential complexity of removing a V8 twin-turbo setup and the importance of verifying engine integrity before any further disassembly. Throughout, the episode blends hands-on troubleshooting with commentary on the structural challenges, such as frame rail condition and the need for careful alignment of critical components before any reassembly. This portion of the rebuild emphasizes safety, the scale of the task, and the learning curve involved in taking on a high-performance machine with extensive damage, setting up expectations for the subsequent installments. In addition, the host teases potential upgrades and improvements that could accompany the rebuild, while also spotlighting the realities of sourcing parts and the constraints around structural repairs. The video closes with a call to follow along for future updates, acknowledging the magnitude of the challenge ahead and inviting viewer engagement on the best path forward for a solid restoration.

Questions answered
- What is the main risk the video highlights when rebuilding a damaged BMW M5?
- The main risk is structural damage to the frame and chassis, which requires precise alignment and often a jig to ensure the car can be reassembled safely.
- Why is the pyro fuse important in this build and how is it being addressed?
- The pyro fuse bridges the electrical connection between body electronics and the engine start and alternator circuits. A replacement fuse is sourced separately and installed to allow the engine to start safely.
- What is the current status of the engine in this first part of the rebuild?
- The engine has been removed from the car so it can be inspected for internal damage and to assess the extent of repairs needed inside the engine compartment.
- What approach is used to assess chassis alignment during this rebuild?
- The builder uses manual measurements between fixed points on the chassis to gauge any movement or distortion, checking if rails or struts are out of alignment and planning to verify with a second-hand crash bar and jig alignment.
