DTC OFF Service, DPF OFF & EGR OFF: Red Coins vs Green Coins
DTC OFF Service, DPF OFF & EGR OFF: Red Coins vs Green Coins
A clear guide for drivers, workshops and tuners: what a DTC means, when a fault requires repair, what a professional DTC OFF file service does, and how Magic Motorsport FLEX Helpdesk coins are used.
If you searched “how can I turn my car DTC off?”, “can I remove a check engine light?”, “DPF OFF service”, or “EGR OFF file service”, the first question is not which button to press. The first question is why the fault appeared. A professional workshop diagnoses the vehicle, checks legality and safety implications, then determines whether repair, a temporary code clear, or an ECU-file service is appropriate.
What does DTC mean in a car?
DTC stands for Diagnostic Trouble Code. It is the code stored by a control unit when it detects a condition outside its expected operating range. Codes may be generic (standardised) or manufacturer-specific. A diagnostic scan identifies the starting point; it is not automatically the diagnosis itself.
What is DTC OFF?
DTC OFF is an ECU calibration/file-service operation that disables a selected diagnostic code from being reported under defined conditions. It is different from simply erasing fault memory with a scan tool. A scan tool can clear stored codes, but the ECU will normally set the code again if it sees the same fault condition. DTC OFF changes the ECU file and therefore must only be considered after competent diagnosis.
Temporary fault-code clear
A diagnostic action that clears the current stored fault memory. If the underlying problem remains, the warning or code can return after the ECU completes its checks.
Professional DTC OFF file service
A selected-code ECU file modification, followed by correct write and validation steps. It does not repair a damaged sensor, wiring issue, mechanical failure or unsafe vehicle.
How a professional DTC OFF service should work
Read faults first
Scan the vehicle and record all codes, freeze-frame data, ECU information and the customer’s symptoms.
Diagnose the cause
Check whether the problem is mechanical, electrical, software-related or caused by an approved modification.
Read & assess ECU file
A compatible programmer such as FLEX reads the ECU/TCU using the supported OBD, Bench or Boot protocol.
Modify, write & verify
A qualified file professional prepares the required file; the workshop writes it safely, verifies communication and road-tests where lawful.

This simplified screen is a visual example for customers. It shows why a workshop needs the original file, ECU identification and validation—not just a fault-code request.
FLEX, DTC removal software and file services: the practical difference
| Item | What it does | What it does not do |
|---|---|---|
| Diagnostic scanner | Reads live data and fault codes; can clear fault memory. | Does not permanently change the ECU calibration. |
| FLEX programmer | Reads and writes supported ECU/TCU files via OBD, Bench or Boot, depending on the vehicle and package. | Does not itself diagnose a mechanical issue or replace professional file knowledge. |
| DTC / ECU file software | Helps a trained professional identify and modify supported calibration areas. | Does not make an unsafe or illegal modification acceptable. |
| File service | Provides the requested, vehicle-specific service after the original file and job details are reviewed. | Should never be treated as a substitute for repair without diagnosis. |
Red Coins vs Green Coins in Magic Motorsport FLEX Helpdesk
FLEX Helpdesk services are paid with virtual coins. The official exchange value is 1 Coin = €1. The coin colour identifies the service group.
Green Coins
Used for selected routine services such as IMMO OFF, VAG MEDC17 cloning and some common DPF/EGR-related services. Current examples include DPF OFF, DPF + EGR OFF, EGR OFF, IMMO OFF and selected decryptor services.
Red Coins
Used for more advanced services, including MOD/STAGE1 file services, BMW ISN extraction, Renault ISK extraction, CVN FIX and many heavy-duty services. Current examples include DTC OFF, AdBlue OFF and ECU Hardware Clone.

Frequently asked questions about DTC OFF, DPF OFF and EGR OFF
Can you permanently turn a car DTC OFF?
A selected DTC can be disabled in a supported ECU file by a qualified professional. This is different from clearing codes with a scanner. However, it must not be used to hide a safety, mechanical or emissions problem.
Does DTC OFF fix my car?
No. DTC OFF does not repair wiring, sensors, injectors, turbochargers, a blocked DPF or any other physical fault. Correct diagnosis comes first.
Can I remove a check engine light with a scan tool?
You can usually clear the stored fault memory, but the warning can return if the ECU sees the same issue again. A fault clear is useful after a repair or as part of diagnosis; it is not a permanent repair.
Is DPF OFF the same as deleting a DPF fault code?
No. DPF OFF is an ECU-file service, while clearing a DPF-related code with diagnostics only clears the current memory. Emissions-system modifications may be illegal for road use; check local law and diagnose the vehicle first.
Which FLEX coin is used for DTC OFF?
The current Magic Motorsport Helpdesk list shows passenger-car DTC OFF as a Red Coin service. The listed price is 80 Red Coins, while heavy-duty DTC OFF is listed separately at 100 Red Coins. Confirm current pricing before ordering.
Which FLEX coin is used for DPF OFF and EGR OFF?
The current list shows DPF OFF, EGR OFF and DPF + EGR OFF as Green Coin services for the listed passenger-car jobs. Heavy-duty versions are separately listed as Red Coin services.
Can Green Coins be changed back to Red Coins?
No. Magic Motorsport states that Red Coins can be converted into Green Coins, but the conversion is irreversible.
Do I need FLEX to request a file service?
FLEX is used by workshops to read and write supported ECU/TCU files. The exact workflow depends on the vehicle, ECU, protocol, package and the service provider’s requirements.
Need the right FLEX package or a professional file-service workflow?
Tell us the vehicle, ECU/TCU details, fault codes, original file availability and intended lawful use. Our team can help you identify the appropriate FLEX coverage and next technical step before you commit.
