Bentley Diagnostics, ECU Programming & VAG-Based Services 

Bentley isn’t just British luxury—it’s German engineering precision underneath. Modern Bentley models like the Continental GT, Flying Spur, and Bentayga run on VAG platforms, packed with shared Audi and VW-derived control systems. These vehicles use the same ECUs, TCUs, BCMs, and CAN architecture found in high-end Audi models, but with a Bentley touch. 

At VAG Programming, we bring expert-level knowledge of the shared systems that keep your Bentley running. Whether it’s key programming, ECU replacement, feature coding, or component protection removal, we’ve got the VAG-level tools—and the experience—to handle it with care and precision. 

Tailored VAG Services for Bentley Vehicles

Your Bentley may come from Crewe, but it speaks fluent Volkswagen Group. We use ODIS, VAS, VCDS, and GEKO platforms to service, adapt, and code the control units that keep everything from your air suspension to your infotainment running smoothly. 

🔍 Advanced Diagnostics & Troubleshooting

Bentleys can include over 100 control modules, particularly in newer Bentayga and Continental GT models. These modules often throw VAG-specific fault codes that generic scanners miss. We address: 

We isolate real faults using VAG-native tools, no generic error-clearing. 

💾 ECU Cloning & Data Transfer

Bentley ECUs, especially MED17/MG1CS003 used in W12 or twin-turbo V8 engines, carry critical immobilizer and VIN data. We perform ECU cloning when: 

We clone full EEPROM and flash content while maintaining Component Security (CS) integrity. 

🧠 Used ECU/TCU Programming & Adaptation

Bentleys often share DL501 or AL952 gearboxes with Audi RS models. Replacing these ECUs/TCUs without coding leads to no communication or limp mode. We provide: 

All programmed with correct parameter sets to avoid software mismatch. 

🔓 Component Protection Removal & GEKO Access

Bentley uses the same Component Protection (CP) system as Audi. That means any module replacement used or new requires GEKO authorization. We remove CP for: 

Especially critical when performing retrofits or repairs with parts from donor vehicles. 

🔐 Key Programming & Immobilizer Coding

Bentley key programming must be done through VAG-compliant tools. We support: 

We make sure your luxury doesn’t get stuck over a key issue. 

🧩 Bentley Feature Coding & Module Retrofits

Many factory options on Bentleys are software-disabled until coded. We enable and code: 

All changes follow VAG’s factory coding format—ensuring functionality and avoiding module conflicts. 

⚙️ Performance ECU / TCU Tuning for Bentley

Despite their weight, Bentleys hide impressive performance potential. We safely enhance this with VAG-platform tuning: 

Each map is tailored to Bentley’s refined powertrain behavior not just dropped in from an Audi. 

Bentley Models We Support

We work with modern Bentley models built on VAG platforms: 

Bentley Continental GT (2012–Present)

Bentley Flying Spur

Bentley Bentayga

Bentley Mulsanne (partial)

Drive a Bentley.
Program it Like a Pro.

Whether it’s diagnostics, a retrofit, or a fresh ECU—VAG Programming knows the Bentley’s internal language.
