Quick Facts

Why is the Renault Twingo III EDC gearbox misbehaving — and what's actually gone wrong?

The 6DCT250 dual-clutch gearbox fitted to the Twingo III is a clever unit, but its electronic control module is a known weak point. When the module — stamped with part number A2C73768910 — starts to fail, you'll typically notice one or more of the following:

• Gearbox stuck in a single gear or refusing to upshift
• Jerky, hesitant or shuddering gear changes at low speed
• A gearbox warning light on the dashboard
• The vehicle going into limp-home mode with restricted performance
• Fault codes stored for the EDC transmission module specifically

The module itself governs how the dual clutches engage and how each gear is selected. When its internal data becomes corrupted or the hardware degrades, the gearbox loses the precise control it needs to operate smoothly — and the car protects itself by limiting what it'll do. A scan tool will point you toward the TCM/EDC module, but replacing it with a blank unit from a parts supplier won't work: a blank module isn't matched to your car, and the gearbox won't communicate with it correctly until it holds your vehicle's calibration data.

That's exactly what cloning solves.

What does the cloning process actually involve?

Cloning transfers the full data set from your original A2C73768910 module — including vehicle-specific calibration, mileage data and transmission adaptation values — onto a tested donor unit. The result is a module that the car recognises as its own from the moment it's plugged in: no dealer visit, no diagnostic reprogramming session, no extra cost.

At The Vehicle Check, every module goes through bench testing before it leaves us. We've been working with automotive electronics across VAG, Mercedes-Benz, Renault, Honda, BMW and Ford platforms for years, and gearbox control modules — from DSG DQ mechatronics to dual-clutch TCMs like the 6DCT250 — are a daily job here, not an occasional one. That depth of hands-on experience with transmission electronics is what separates a proper cloning service from a roll-of-the-dice swap.

Is cloning really better than buying a second-hand module or going to a Renault dealer?

A second-hand module from a breaker is the riskiest route: you don't know its history, it won't be matched to your car's calibration data, and you'll almost certainly still need a coding session to make it work — assuming it works at all. Cloning eliminates that gamble.

We also handle clutch actuator repairs if your dual-clutch setup has mechanical as well as electronic faults, and BCM/BSI cloning for any body control module issues running alongside your gearbox fault.

How do I safely package and post my EDC module to you?

Removing the A2C73768910 module from the Twingo III is a job most competent DIY mechanics or independent garages can handle. Once it's out, here's how to get it to us safely:

1. Wrap the module in at least two layers of bubble wrap. Anti-static bags are ideal if you have one, but clean bubble wrap is fine.
2. Place it in a rigid box — a shoebox-sized cardboard box with packing foam or scrunched paper to stop it moving is perfect. Avoid padded envelopes for electronics.
3. Include a note inside with your full name, contact phone number, vehicle registration and a brief description of the fault.
4. Use a tracked courier service — Royal Mail Tracked 48/24, DPD, Evri or similar. Keep your tracking number until the job is complete.
5. Send to: Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ.

Once we've received and cloned your module, we'll send it back via free tracked return delivery. International customers — please call or email us before sending so we can confirm the best return shipping method for your country.

If your car has also suffered an electrical event or accident, take a look at our SRS airbag and crash data reset services — it's common for multiple modules to be affected at once.
