Key Features
- EEPROM/MCU data extraction from MQB48 clusters — every major NEC variant supported.
- Immobiliser block recovery, component security (CS) retrieval and key slot / key ID reading.
- VIN and sync data recovery for cluster swaps, ECU replacements and MQB48 retrofits.
- All-keys-lost solutions when OBD access is blocked or the dashboard is locked.
Service Overview
- If you own or work on VAG MQB48 vehicles you already know how complex the immobiliser system is — locked dashboards, encrypted NEC processors and blocked OBD access turn a simple key job into a nightmare. This service covers professional MQB48 EEPROM/MCU reading and immobiliser data extraction across every major NEC chip variant used on the platform.
- Covered work: EEPROM/MCU data extraction, immobiliser block recovery, component security retrieval, key slot & key ID reading, VIN and sync data recovery, cluster replacement IMMO transfer, ECU/cluster pairing and sync repair, plus full all-keys-lost MQB48 solutions.
- Ideal for lost key situations, blocked OBD access, dashboard swaps, ECU replacements, corrupted EEPROM, IMMO mismatch issues and MQB48 retrofits.
- Who it's for: VAG owners needing key or IMMO help, automotive locksmiths, ECU/cluster repair technicians, retrofitters, MQB48 coders and workshops needing reliable EEPROM extraction.
- Optional add-ons: key programming and pre-coded MQB48 keys. Postal service as standard from our Wolverhampton bench; mobile attendance across the West Midlands with a postcode-based call-out fee.
- Please note: on VAG all-keys-lost the price varies depending on whether the car is KESSY/proximity or blade key, and manual or automatic, due to component security (CS) code requirements.

Frequently Asked Questions
Why does the price vary on VAG all-keys-lost?
MQB48 pricing depends on the setup: KESSY/proximity systems cost more than blade keys, and manual vs automatic changes the work needed because of component security (CS) code requirements. Send your registration and we will confirm the exact price before you commit.
Which NEC chips do you support?
D70F3524, D70F3525, D70F3526, D70F3529, D70F3532, D70F3535, D70F3536 and D70F3537 — including the A2C-series board variants and their extended adapter compatibility.
Can you help if OBD access is blocked?
Yes. Locked or protected MQB48 dashboards are read directly on the bench, so blocked OBD security access is not a barrier.
Do you supply keys as well?
Yes — key programming and pre-coded MQB48 keys are available as optional add-ons on top of the data extraction service.
Not sure your car is compatible?
Send your VIN and we'll confirm compatibility before you order. We cover CAS1, CAS2, CAS3, CAS3+, CAS4/CAS4+, FEM/BDC and BDC2.
