BMW E90 Clutch Switch / No-Start Diagnosis

I'm troubleshooting a manual BMW E90 that won't crank, with attention on the clutch-pedal switch and starting interlock. If the dashboard wakes up but the starter won't engage, this video shows the clutch-switch side of one BMW no-start investigation rather than telling you to replace the starter immediately.

What you’ll see in this one

A no-crank and a crank-but-won't-start are different problems. The clutch switch is one input worth checking on a manual E90.

A closer look at this job

This manual-transmission BMW E90/E92/E93 no-crank video addresses the clutch pedal switch as part of the starter-enable circuit. A car that does not crank can have battery, ground, starter, wiring or interlock issues; a switch-related symptom needs checking before any part is condemned. The recording follows a clutch-switch investigation on the car. Searches for '335i won't crank with clutch pressed' and 'E90 clutch safety switch' lead to this page. Use vehicle-specific wiring diagrams for electrical measurements.
