Dealer quotes for luxury vehicle module repair are not luxury prices — they are monopoly prices. The dealer’s only real advantage is the programming tool. We have the same capability.

What Factory-Level Equipment Means for You
BMW ISN Reading
We read ISN codes directly from BMW DME/DDE memory using BIMTOOL Pro — without removing or soldering the MCU chip. Non-destructive and identical to what BMW dealer technicians do.
Mercedes EIS/EZS Coding
We recode Mercedes EIS and EZS ignition switch modules using XENTRY-compatible programming sequences — the same process authorized dealers use at a fraction of the cost.
JLR KVM Programming
JLR Key and Vehicle Module programming via Autel IM608 Pro II and JLR-specific adapter sequences — including all-keys-lost recovery for Range Rover and Defender platforms.
EEPROM Read/Write
We read and write EEPROM and flash memory on ECU boards — restoring corrupted data, extracting pin codes, and repairing failed modules at the component level across all luxury platforms.
Repair vs Dealer Replacement — Why It Matters More on Luxury Vehicles
On a domestic vehicle, a new ECU might cost a few hundred dollars. On a BMW, Mercedes, or Porsche, a new module often runs thousands — and that’s before dealer programming labor. The dealer’s programming cost alone can exceed what the entire repair costs us to perform.
We repair the existing module at the component level. Your VIN data stays intact. In most cases, no dealer reprogramming is needed after installation. Contact us with your vehicle and module details for a free quote.
- ✓Save significantly vs new OEM module + dealer programming
- ✓VIN, key, and calibration data preserved — plug-and-play in most cases
- ✓48–72 hour turnaround — faster than waiting for OEM parts
- ✓12-month warranty — same guarantee we give on every repair

Luxury ECU Repair FAQ
Can you really repair a BMW CAS module without going to the dealer?
Yes. We read and write the ISN security code and key data directly from the CAS module’s memory using BIMTOOL Pro — the same operation dealers charge premium rates to perform. The repaired module is plug-and-play on your vehicle.
What’s the difference between ECU repair and ECU replacement?
Replacement means buying a new or used module and reprogramming it to your VIN — often requiring dealer-level tools. Repair means we fix the existing module: replacing failed capacitors, relays, or memory chips, then reprogramming. Repair is always preferable when possible because your existing VIN data is preserved and no dealer visit is needed after installation.
How do I ship my module safely?
Wrap the module in two layers of bubble wrap or foam, place in a rigid box with padding on all sides, and seal with tape. Avoid plastic bags alone — static can damage EEPROM chips. Ship with insurance and tracking via UPS, FedEx, or USPS Priority Mail. Email us the tracking number after shipping.
Do you guarantee the repair will work?
Yes. If we cannot repair your module, we ship it back at no charge and you owe nothing. If the repair fails within 12 months, we repair it again at no cost. Our money-back guarantee is unconditional.
Can you handle Porsche DME repair by mail?
Yes. Porsche DME (Digital Motor Electronics) units for Cayenne, Panamera, Macan, and 911 models are all compatible with our repair process. We handle Bosch ME7, ME9.6, and other common Porsche ECU variants. Turnaround is standard 48–72 hours.
What Range Rover modules can you repair?
We repair the KVM (Key and Vehicle Module), ECU/ECM, and BCM for L322, L405, and L460 Range Rover platforms, as well as Range Rover Sport and Discovery. All-keys-lost recovery is available for most JLR platforms.
