Description

Professional SCR and DPF delete tuning service for UD Trucks manufactured in 2014 and later is available through the Mochester App. Equipment requirements are very simple. The entire programming process is performed remotely using your communication adapter and a laptop. The process is fast, safe, and typically completed in 20 minutes or less. We also provide a limited lifetime warranty on our work.

To begin, simply install the Mochester App and follow the step-by-step instructions.

Applicability

UD Trucks version 3, version 4 DPF/SCR delete solution through reprogramming.

When is the service needed?

If the cost of fixing your truck’s emission systems is getting too expensive, our remote tuning service may be the perfect solution.

Derates, loss of power, poor fuel economy, and costly downtime that keep your truck off the road are often caused by a clogged DPF filter or a failing SCR system.

Our remote tuning service solves these problems by professionally deleting the DPF and SCR systems through ECU software reprogramming. This eliminates some of the most common emissions-related failures and significantly lowers the ongoing maintenance costs associated with factory emission equipment.

And if you’d rather get ahead of the problem before it starts, this service is for you too. Proactively deleting these systems before they fail means you’ll never have to deal with those expensive repair bills in the first place. Once tuned, your truck will run without constant regeneration issues, DPF restrictions, SCR system faults, repeated sensor failures, or performance loss from soot buildup and exhaust restrictions. The result is a more dependable truck with less downtime and fewer disruptions.

Guides & Instructions

Tuning results

  • No SCR/DPF fault codes
  • No torque reduction
  • No warning lamps on the dashboard
  • Minimal intervention into current ECU Calibration. We know what we do. No one unrelated parameter will be changed
  • 3 or 4 SCR-related ECUs are reprogrammed together

Required hardware changes after tuning


ATTENTION!
After applying our DPF/SCR delete service:

  • ACM (Aftertreatment Control Module) and both NOx sensors must remain unplugged indefinitely! Plugging them back in will cause a “soot level high” message and immediate engine derate!

Exception: on EU trucks equipped with a transmission brake the ACM should remain connected but the Engine CAN wires (pins 1 and 5 in the ACM connector) must be cut off.

  • We also strongly recommend bypassing the SCR cans or removing them

Warranty Terms and Conditions

This product is covered by D3LW™ program. D3LW is DrunkLab Limited Lifetime Warranty.

Warranty cases are resolved in priority order. The policy is “fix or return,” which means a full refund if it is impossible to fix the problem immediately.

Warranty cases are:

  • Configuration errors
  • ECM memory — related fault codes appear after flashing
  • Aftertreatment system fault codes (not including instrument cluster reagent level code)

Non — warranty cases are:

  • ECU replacement (different ECU serial numbers detected than stored into database during reprogramming)
  • Software update campaign performed (different software detected)
  • ACM connection after programming (for trucks not equipped with a retarder)
  • Cracking/readout attempts detected (different fingerprint is stored into ECU)

Company advantages

  • Fast tuning: With the Mochester App (M4 App), customers can order and apply tuning solutions without scheduling TeamViewer sessions.
  • Safe and Controlled Tuning Workflow: The OTP-based confirmation system, the guided and approved connection, and the verified tuning process protect against the risks of incorrect programming and/or configuration
  • Wide hardware compatibility: Works with the RP1210-compatible adapters including Nexiq, Noregon, DPA5, Inline 6, and Scanmatik
  • Advanced 2014+ vehicle support: The Mochester App, combined with the VLOMINGO Tuning Adapter works with Volvo, Mack, Renault, UD, Prevost, Volvo CE, and Volvo Penta platforms, and also provides access to TRW EMS 2.3 and TRW EMS 2.4 ECUs
  • Advanced 2023+ and 2025+ vehicle support: Mochester App with the RAZDOLBOSCH Tuning Adapter provides wide support for 2025+ (USA) Volvo and Mack trucks, Prevost and Volvo buses, as well as 2023+ (Euro 6) Volvo and Renault trucks and Volvo buses, including protected and difficult-to-access modern Bosch ECM 4.x platforms
  • 24/7 technical assistance: Integrated support system with rapid diagnostics assistance, warranty handling, and troubleshooting through chat on dl.ge website, WhatsApp, or the Mochester App (M4 App) support section

Additional Information

It’s a remote ECU reprogramming that disables the DPF (diesel particulate filter) and SCR (AdBlue/DEF) systems. In plain terms, the truck is set up to run without any regeneration cycles or DEF-related controls interfering.

This tuning service is for operators who are tired of dealing with constant emissions headaches and just want their truck to run reliably day after day. On these 2014+ UD Trucks, the DPF and SCR systems are deeply integrated into the engine management, so when something goes wrong, it usually affects the whole vehicle.

As the miles add up, typical problems start appearing: DPF filters clog more often, regens become frequent and annoying, and the SCR system throws DEF faults. NOx sensors can fail out of nowhere, bringing warning lights, power derates, or even limp mode. Instead of constantly replacing expensive parts and chasing the same issues, this service retunes the ECU so the engine no longer relies on the DPF and SCR systems. After the update, the truck stops doing forced regens and ignores most DEF-related faults that normally trigger derates.

The difference is noticeable in real-world use. Power delivery feels smoother and more consistent, there are far fewer interruptions, and the engine isn’t constantly reacting to faulty sensor data. This is especially helpful for heavy-duty work or long-haul operations. The main priority is safe, stable engine operation after removing the emissions systems that cause the most downtime. If you want, we can also add performance tuning in the same session.

Key Benefits:

  • Removes DPF and SCR (AdBlue/DEF) control on UD Trucks V3 / V4 (2014+), depending on your setup
  • No more forced regens getting in the way of your work
  • Clears up the usual DEF faults and NOx sensor-related problems
  • Helps keep the truck out of derate and avoids unexpected power loss
  • Smoother, more predictable performance when the truck is under load
  • Cuts down on time and money spent fixing emissions-related issues
  • Done remotely, so there’s no need to remove or ship the ECU
