Having problems with a failed BMW F-Series SZL (Steering Column Switch Cluster)?

With this service, you only need to mail us your original SZL module. Lacorte Automotive provides a compatible remanufactured replacement SZL, transfers the applicable vehicle-specific data and configuration from your original module, bench tests the replacement, and ships the completed unit back to you.

YOU SEND YOUR ORIGINAL — WE PROVIDE THE REPLACEMENT

No donor SZL required.

Every remanufactured SZL supplied through this service includes our 3-Year Warranty.

Common SZL Failure Symptoms

Depending on the vehicle and SZL configuration, a failing Steering Column Switch Cluster can cause symptoms including:

• Turn signals not working
• Turn signals not cancelling properly
• Windshield wiper control problems
• Steering-wheel button or multifunction-control issues
• Steering angle sensor faults
• DSC / stability-control warning lights
• ABS/DSC warnings associated with steering-angle information
• Cruise-control problems on applicable vehicles
• Steering-column controls operating intermittently
• Multiple steering-column-related fault codes
• SZL communication faults
• Module intermittently dropping offline
• Diagnostic equipment unable to communicate with the SZL
• Internal electronic or memory failure
• Physical, electrical, or moisture damage

Exact symptoms vary by vehicle and configuration.

Proper diagnosis is recommended before ordering. Wiring, connectors, clock spring components, steering-angle calibration, battery voltage, other control modules, or mechanical steering components can cause similar symptoms.

Proof of Ownership Required

Because automotive control modules can contain vehicle-specific configuration information, proof of vehicle ownership is required before service is performed.

Please provide:

• Government-issued photo ID
• Vehicle title or current registration
• Vehicle VIN

Documentation must correspond with the vehicle being serviced.

Important — Compatibility

This is a mail-in remanufactured BMW SZL replacement service.

Compatibility depends on factors including:

• BMW part number
• SZL hardware version
• Software version
• Vehicle chassis
• Production date
• Installed vehicle options
• Original module configuration

If the required information cannot be recovered from your original SZL because of severe physical, electrical, or memory damage, additional programming or vehicle-side work may be required.

Not Sure If Yours Is Compatible?

Send us:

• Clear photo of your original SZL label
• Vehicle year/model
• VIN

We'll help verify compatibility before you ship your module.
