Terrible experience at BMMPower! Brought in my BMW X1 2010 for timing chain diagnostics, but received no report despite being billed for the service. Their phone diagnosis was not only wrong but way off from the actual issue. Instead of addressing the timing chain problem as I suspected, they insisted it was a rod knock. Another mechanic later confirmed their incompetence as the issue wasn't rod knock at all! Still waiting for the report, but it's clear BMMPower's mechanics are clueless with BMWs. Don't risk your vehicle here—choose competence over chaos!
