Mercedes-Benz C300 ignition key not turning issue due to steering wheel lock contact, common problem on Mercedes-Benz C300

Some Mercedes-Benz C300 owners report experiencing difficulties with their ignition key not turning, often due to a binding steering column or lock. This issue may arise when the steering wheel lock prevents the key from turning in the ignition, which can be linked to a faulty steering lock module (ESL). To resolve this problem, owners should diagnose and potentially replace the defective steering lock module. Additionally, checking the steering wheel lock for any malfunctions and ensuring it operates correctly can aid in addressing the ignition key turning issue.
