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, in practice that is the G-series cars: the G20/G21 3-Series, G30/G31 5-Series, G22/G23 4-Series, G42 2-Series, G32 6-Series GT, G01 X3, G02 X4, G05 X5, G06 X6, G07 X7 and the M cars (G80 M3, G82 M4, G87 M2). Late F-chassis cars built after that date are affected too.

We now unlock these ECUs in-house on the bench. The unit is removed, opened and unlocked on the bench. Only once it’s unlocked can its data be read and your original file saved, 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.
Which Tools Work Afterwards
This depends on the car. On a BMW or Alpina, every ECU we unlock — MD1CP032, MD1CS001, MG1CS024, MG1CS049 and MG1CS201 — is left open to any standard OBD tool afterwards, which is why we do them all in-house. On an Audi, VAG, Porsche or Bentley it depends on the route: after a Magic unlock the ECU is read and written with the Flex tool only, while after an Autotuner unlock it is open to any standard OBD tool — Flex, MG Flasher and others, which makes future work easier.
Pricing
  • BMW & Alpina — £100 inc VAT added to a tuning booking, or £200 on its own. In-house on the bench, same day, with no longer appointment needed.
  • Audi, VAG, Porsche & Bentley — £449 inc VAT in-house, or £399 sent away, when added to a tuning booking. On their own: £549 in-house or £499 sent away.
  • Done in-house on the bench, no ECU sent away
  • Original file saved once unlocked
  • Included in your tuning booking, or bookable on its own

Just want the unlock?

If you’re having the car tuned somewhere else, we’ll still unlock it. Drop it with us for the day and pick it up unlocked, with your original file saved.

BMW & Alpina

The Bosch ECUs in these cars are quick to open on our own bench, so they are in-house only — there is no send-away option, because it would be slower and dearer.

Same day
In-house bench unlock
£200

Drop it off in the morning, collect it unlocked with your original file saved. Every BMW and Alpina ECU we unlock is left open to any standard OBD tool afterwards.

Having us tune it as well? Unlocking drops by £100, because it’s done as part of the same job: £100 on a BMW or Alpina, or £449 in-house / £399 sent away on an Audi, VAG, Porsche or Bentley. Our 100% success rate and our replacement cover apply either way.

Bosch MDG1 Line-Up

Compatible with Bosch MDG1 ECUs featuring Aurix TC298 and TC299 microprocessors, and we're just getting started.

A locked ECU can’t be read or backed up until it’s unlocked, so the unlock always happens first. We have the process mastered across every ECU listed below, including the newest ones, and your original file is saved the moment it comes off. Our replacement cover applies either way, see section 23 of the booking terms.

Send-away only These ECUs can’t be unlocked on the bench in a same-day appointment — the unit has to come out and be sent away. Your car can stay with us while that happens, or you can post the ECU in on its own. Everything else on this page is done in-house while you wait.

No match, but our list is growing all the time. Send us your ECU part number and we’ll confirm.

More manufacturers — Audi, VW, Seat, Škoda, Cupra, Porsche and more, are covered by the ECUs listed above, with full model breakdowns being added here. Don’t see your car? Get in touch with your registration or ECU part number.

How It Works

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

1
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.
2
Bench Unlock
The ECU is removed, opened and unlocked on the bench with professional equipment. Only once it’s unlocked can the data be read and your original file saved.
3
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.

Why DC Remapping UK

Serious equipment, in-house capability and 14+ years on Bosch ECUs.

Done In-House
We unlock on our own bench in Warrington, no sending your ECU off to a third party, no waiting weeks for it to come back.
Data Protected
Once unlocked, we read and save your original file, so any tune we apply is fully reversible.
Constantly Growing
Our supported line-up keeps expanding across BMW, VAG and Porsche. New ECUs added regularly.
With A Tune, Or On Its Own
Unlocking is included in your tuning booking, or available on its own if you’re tuning the car elsewhere. Standalone is priced separately.

What’s Covered

Straight answers on who we unlock for, the success rate, and exactly what we cover if it goes wrong.

Unlocking with a tune, or on its own

Most people have us unlock and tune in one visit, and that is the cheaper way to do it. If you would rather tune the car elsewhere we will still unlock it, Standalone unlocking is priced separately and is only offered where we can leave the ECU usable with your chosen tuner, we confirm that for your exact ECU before you book.

100% success rate

Bench unlocking is an established, controlled process and every ECU we have unlocked has come through it without any issue. It is still delicate work rather than a risk-free one, which is why our replacement cover is written into the booking terms — but our record stands at 100%.

If an ECU doesn’t survive, we cover it

In the unlikely event an ECU fails during unlocking, DC Remapping Ltd will supply and code a replacement unit of equivalent specification, new, reconditioned or used at our discretion, provided it restores the car to full working order. You won’t be left with the bill for the part or the programming.

What that cover does & doesn’t include

Our cover is limited to the replacement ECU and its coding. It does not extend to hire or courtesy cars, recovery, travel, loss of earnings, or any other knock-on costs.

By booking in, you accept that unlocking carries a risk, and that DC Remapping Ltd’s liability is limited to the cost of the replacement ECU and coding as set out above.

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?+
Most of them, yes. The ECU comes out, goes on our own bench here in Warrington, and is refitted the same day, so you drive away that day. A number of ECUs cannot be done that way and have to be sent away instead, those come back open to any standard OBD tool in 3–4 working days, and your car can stay with us while it happens. Every ECU on the list further down this page is marked with which of the two applies, and we confirm it before you book.
How much does ECU unlocking cost?+
It depends on the car. BMW & Alpina: the Bosch ECUs fitted are now quick to open on our bench, so it is £100 inc VAT added to a tuning booking, £200 on its own, or £230 posted in — all in-house, same day, and they no longer need a longer appointment. Audi, VW, SEAT, Skoda, Cupra, Porsche & Bentley are unchanged — it depends whether the unlock is part of a tune with us or on its own. Added to a tuning booking: £449 inc VAT in-house on our own bench (Magic), same day, or £399 inc VAT sent away (Autotuner), 3–4 working days with your car staying here. On its own, if you are tuning the car elsewhere: £549 inc VAT in-house, or £499 inc VAT sent away. Posting the ECU in from anywhere in the UK is £579, being £549 plus £30 tracked and insured return postage. Every BMW and Alpina ECU we unlock — MD1CP032, MD1CS001, MG1CS024, MG1CS049 and MG1CS201 — is left open to any standard OBD tool afterwards. On the other makes, an in-house Magic unlock leaves the ECU readable with the Flex tool only, while an Autotuner unlock leaves it open to any standard OBD tool.
Which ECUs can you unlock?+
We unlock the Bosch MDG1 family running Aurix TC298 and TC299 microprocessors across BMW, VAG and Porsche. 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?+
Bench unlocking is a controlled, established process done in-house with professional equipment. We're always straight about one thing: a locked ECU can't be read or backed up until it's unlocked, so the unlock has to happen first. The vast majority unlock cleanly with no flip required. A small number of the newest ECUs need a 'flip', an advanced procedure that carries a small but genuine risk, and because no backup is possible beforehand, we always tell you if your car is one of them before we start. Once unlocked, we save your original file so any tune is fully reversible. Every ECU we have unlocked has come through without any issue, a 100% record to date, and in the unlikely event one ever didn’t survive, we supply and code a replacement unit of equivalent specification, new, reconditioned or used at our discretion (that cover is limited to the unit and its coding, see Before You Book).
Which tools can I tune the unlocked ECU with?+
It depends on the car. On a BMW or Alpina every ECU we unlock — MD1CP032, MD1CS001, MG1CS024, MG1CS049 and MG1CS201 — is left open to any standard OBD tool afterwards, so there is nothing to gain from sending one away. On an Audi, VAG, Porsche or Bentley you choose the route: after an in-house Magic unlock the ECU is read and written with the Flex tool only; after an Autotuner unlock it is open to any standard OBD tool — Flex, MG Flasher and others, which makes future work easier.
Do you offer unlocking on its own?+
Yes. You don’t have to be having the car tuned with us. BMW & Alpina: £200 inc VAT on our own bench, same day, or £230 posted in (£200 plus £30 tracked and insured return postage). Audi, VAG, Porsche & Bentley: bring it to Warrington and we unlock it on our own bench the same day (£549 inc VAT), leave it with us and the ECU goes away and comes back open to any standard OBD tool in 3–4 working days (£499 inc VAT), or if you are nowhere near us, take the ECU out yourself and post it in — £579, being £549 for the unlock plus £30 tracked and insured return postage, with higher cover available. Sending it to us is at your own cost. Mail-in covers 2020 to 2025 cars, which is the locked-ECU era, and is unlock only: tuning is done on our own 4WD dyno, so the car has to be here for that.
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, MG1CS008, MG1CS031, MG1CS163), the MG1CS008 covers the 4.0 V8 TFSI shared across Audi RS/S, Bentley, Lamborghini Urus and Porsche. It keeps growing, send your part number for confirmation.

Send Us Your ECU

Not near Warrington? Pay below and we’ll email you our address and exactly what to send. Remove the ECU yourself and arrange the delivery to us at your own cost — we recommend DHL, tracked and properly insured. Covers 2020 to 2025 vehicles, which is the locked-ECU era.

Mail-in unlocking covers 2020 to 2025. Outside that your ECU almost certainly isn’t locked, so give us a call before sending anything.

Optional, but it saves a lot of back and forth. It’s the Bosch number on the sticker, and you’ll be able to read it once the ECU is out.

If you want it tuned, the vehicle must be present. We tune on our own 4WD dyno, so the car has to come to the Warrington workshop, we can’t do it from a posted ECU. Please go to the book online page to get it booked in. We are closed Wednesdays and Sundays.

Pick the cover level that suits the value of your ECU. This is the return leg only — sending it to us is your own arrangement and cost, and we recommend DHL with the ECU insured for its replacement value.

Total to pay today£579.00 £549 unlock + £30.00 return postage

Sending it to us is your arrangement 🚚 You book and pay for the delivery to us, so the contract is between you and the carrier — if it goes missing or gets damaged on the way here, the claim is theirs to settle with you, not ours. We recommend DHL, and please insure it for what the ECU is actually worth to replace, not what the postage costs. Send it tracked and keep the tracking number until we confirm it has arrived. The postage you pay above is the return leg only, back to you.

Packing the ECU 📦 Protect the ECU properly during transit. Pack it securely so it can’t move around inside the box, with padding on every side and nothing pressing on the connector pins. A rigid box beats a jiffy bag.

Please don’t open the ECU. It must arrive sealed and untouched, exactly as it came out of the car. An opened ECU can’t be unlocked and we can’t refund it.

If your ECU isn’t supported, we refund the £549 unlock fee in full and post it straight back. The return postage fee is not refundable, as we still have to send it to you.
