Bosch MDG1 ECU Unlocking — Bench Unlock

The Service

What Is ECU Unlocking?

Many of the latest ECUs are locked from the factory — the manufacturer protects them so they can't be read or written through the OBD port or with standard tools. Until the ECU is unlocked, no tuning, DTC work or software solution can be applied. On BMWs, this applies to ECUs with a build date after June 2020.

We now unlock these ECUs in-house on the bench. The unit is removed, opened, its original data safely read and backed up, and the ECU is unlocked — ready to be read, modified and written. It's the crucial groundwork that makes everything else possible on these platforms.

We're proud to be able to offer this on the Bosch MDG1 range featuring Aurix TC298 and TC299 microprocessors — and the supported list is growing all the time.

Bench, Not OBD

These ECUs cannot be unlocked through the diagnostic port. The unit is unlocked on the bench with professional equipment, with your original data read and stored first so the ECU can always be returned to its starting state.

The Process

How It Works

A clean, controlled bench process — your ECU is protected at every step.

Identify

We confirm your exact ECU part number and processor to make sure it's on the supported MDG1 (TC298 / TC299) list before any work begins.

Bench Unlock

The ECU is removed and opened on the bench. Your original data is read and safely backed up, then the ECU is unlocked with professional equipment.

Read, Tune & Refit

With the ECU unlocked we can read, apply your tuning or software solution and write it back. The ECU is refitted and tested — job done, in-house.

FAQs

ECU Unlocking Questions

What is ECU unlocking and why is it needed?+

Many modern Bosch MDG1 ECUs (with Aurix TC298 and TC299 microprocessors) are locked by the manufacturer, meaning the ECU can't be read or written through the OBD port or standard tools. Unlocking opens the ECU so it can be read and reprogrammed — the essential first step before any tuning or software solution can be applied.

Do you unlock the ECU in-house?+

Yes. We unlock these ECUs on the bench in-house at our Warrington workshop — the ECU is removed, opened on the bench and unlocked, then refitted. No sending your ECU away to a third party and no long waits.

How much does ECU unlocking cost?+

Unlocking is £349 inc VAT per ECU.

Which ECUs can you unlock?+

We unlock the Bosch MDG1 family running Aurix TC298 and TC299 microprocessors across BMW, VAG, Ford, JLR, Hyundai/Kia, Stellantis, Iveco and more. The supported list is growing all the time — get in touch with your ECU part number and we'll confirm.

Is unlocking safe for my ECU?+

Yes. Bench unlocking is a controlled, established process carried out with professional equipment. Your original data is read and backed up first, so the ECU can always be returned to its original state.

Do you offer this as a trade service?+

Yes — we support other tuners and workshops with bench unlocking and software solutions on these platforms. Contact us to discuss trade work and turnaround.

Can I post my ECU to you, or do I have to bring the car in?+

Both. You can bring your vehicle to our Warrington workshop, or post the ECU to us from anywhere in the UK. We unlock it in-house on the bench, back up your original data and send it straight back — usually within a couple of working days of arrival. This applies to private customers and the trade alike.

Can you unlock a locked BMW MG1CS024 or MG1CS201?+

Yes. The BMW petrol MG1CS024 and MG1CS201 are both supported, along with the newer MG1CS049 and the diesel MD1CP032 and MD1CS001. Send us your exact ECU part number and we’ll confirm.

Can you unlock Porsche, VAG and other MG1 / MD1 ECUs?+

Yes. Our supported line-up includes Porsche (MG1CP007, MG1CS047, MG1CS008), VAG (MD1CS004, MD1CS014, MG1CS002, MG1CS031, MG1CS163), Ford, JLR, Hyundai/Kia, Stellantis, Iveco, Isuzu and Fiat. It keeps growing — send your part number for confirmation.
