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

Lacorte Automotive offers professional mail-in Porsche BCM cloning for supported modules using the 1L15Y, 1N35H, 2M25J, and 5M48H variants.

Simply send us your original BCM and a compatible replacement/donor BCM. We transfer the applicable vehicle-specific data from your original module to the replacement, bench test and verify the completed unit, and ship both modules back to you.

Common BCM Failure Symptoms

The BCM controls or communicates with numerous electrical systems throughout the vehicle. A defective module can therefore cause multiple seemingly unrelated electrical problems.

Common symptoms may include:

• Vehicle will not start or has intermittent starting problems
• Key or immobilizer-related faults
• Central locking problems
• Doors will not lock or unlock correctly
• Interior or exterior lighting malfunctions
• Power window problems
• Alarm system malfunctions
• Convenience feature problems
• Multiple warning messages
• Multiple electrical systems failing simultaneously
• CAN/network communication faults
• Diagnostic equipment unable to communicate with the BCM
• BCM intermittently dropping offline
• Battery drain or modules failing to enter sleep mode
• Water or moisture-damaged BCM
• Internal processor or memory failure
• Replacement BCM requires original vehicle data transferred

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

Supported Porsche BCM Variants

Our current service supports:

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

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

• EEPROM/module data
• PFLASH data
• Convenience module data
• Convenience PFLASH data
• Vehicle-specific configuration

The exact data transferred depends on the original BCM and replacement module.

Applicable Porsche Vehicles

These BCM families may be found across various Porsche platforms and model years. Exact compatibility must be determined by the BCM part number, processor, hardware/software version, and vehicle configuration, rather than vehicle model alone.

If you're unsure whether your Porsche is supported, send us:

• Vehicle year
• Vehicle model
• VIN
• Clear picture of the original BCM label
• Clear picture of the replacement BCM label

We'll help verify compatibility before you ship the modules.

How It Works

1. Purchase the Service

Place your order through our website.

2. Mail Us Both BCMs

Send us:

• Original Porsche BCM
• Compatible replacement/donor BCM

3. We Clone Your Original Data

We transfer the applicable data from your original BCM to the compatible replacement module.

Depending on the BCM, this may include EEPROM, PFLASH, Convenience and other applicable vehicle-specific information.

4. Tested & Verified

The completed replacement BCM is bench checked and verified before return.

5. We Ship Everything Back

Your original BCM and completed replacement module are securely packaged and shipped back to you.

Fast 1–2 Business Day Turnaround

We know a failed BCM can cause widespread electrical problems or leave your Porsche completely unusable.

That's why Lacorte Automotive pushes for a typical 1–2 business day turnaround after receiving your modules.

Our goal is to complete the service and get your modules back on their way as quickly as possible.

What You Need to Send

You Send:

• Original Porsche BCM
• Compatible replacement/donor BCM
• Vehicle VIN
• Required ownership documentation

We Perform:

• Applicable original data transfer
• BCM cloning
• Bench testing and verification

You Receive:

Your original BCM and completed cloned replacement BCM returned to you.

Replacement/donor BCM is NOT included with this listing.

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 listing is for a mail-in Porsche BCM cloning service only.

The customer supplies both the original and replacement BCM.

Compatibility depends on the exact part number, processor, hardware version, software version, and vehicle configuration. A replacement BCM that physically looks identical is not necessarily compatible.

If the original BCM is severely physically or electronically damaged and the required data cannot be recovered, cloning may not be possible. We will contact you if the standard service cannot be completed.

Not Sure If Your BCM Is Compatible?

Send us pictures of the original and replacement module labels along with your VIN before ordering and we'll help verify compatibility.
