Having electrical problems, communication faults, convenience-system issues, or a failed Porsche Body Control Module (BCM)?

With this service, you simply mail us your original BCM. Lacorte Automotive supplies a compatible remanufactured replacement BCM, transfers the applicable vehicle-specific data 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 BCM required.

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

Common BCM Failure Symptoms

The BCM is involved with numerous body electrical and convenience functions. A defective BCM can cause several seemingly unrelated problems, including:

• Central locking problems
• Doors intermittently failing to lock or unlock
• Key or immobilizer-related faults
• Interior lighting malfunctions
• Exterior lighting problems
• Power window or mirror issues
• Alarm system problems
• Convenience features becoming unavailable
• Multiple electrical systems malfunctioning simultaneously
• CAN/network communication faults
• Diagnostic equipment unable to communicate with the BCM
• BCM intermittently dropping offline
• Battery drain
• Modules failing to properly enter sleep mode
• Intermittent starting problems
• Water or moisture damage
• Internal processor or memory failure

Proper diagnosis is recommended before ordering. Battery voltage, wiring, grounds, connectors, CAN network problems, water intrusion, or another defective control module can produce similar symptoms.

Supported Porsche BCM Variants

This service currently supports:

• BCM – 1L15Y
• BCM – 1N35H
• BCM – 2M25J
• BCM – 5M48H

Depending on the module version, our service can include transfer of applicable:

• EEPROM/module data
• PFLASH data
• Convenience module data
• Convenience PFLASH data
• Original vehicle configuration

Porsche Applications

These BCM variants may be used across different Porsche platforms and model years.

Because Porsche used different hardware and software configurations, compatibility must be determined by the original BCM part number, processor, hardware/software version, and vehicle configuration rather than vehicle model alone.

Not sure whether yours is supported? Send us:

• Vehicle year
• Porsche model
• VIN
• Clear picture of your original BCM label

We'll help verify compatibility before you order.

Proof of Ownership Required

Because BCMs may contain vehicle-specific security, immobilizer, key, and configuration information, proof of vehicle ownership is required before service is performed.

Please provide:

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

Documentation must correspond with the vehicle being serviced.

Important — Please Read Before Ordering

This is a mail-in remanufactured BCM replacement service.

Compatibility depends on the exact part number, processor, hardware version, software version, and vehicle configuration.

If your original BCM has suffered severe physical, electrical, or memory damage and the required data cannot be recovered, the standard service may not be possible. We will contact you if additional work is required.

Not Sure If Your BCM Is Compatible?

Send us a clear photo of your original BCM label, vehicle year/model, and VIN before ordering.
