What is DPF OFF?
The diesel particulate filter collects soot and regenerates during operation. DPF OFF refers to vehicle-specific software changes to filter monitoring and the regeneration strategy.

FAULT CODES · DTC · OBD
Common fault codes and their meanings.
These codes are frequently read during inquiries about this system. A DTC identifies the detected deviation – the actual cause emerges only from the vehicle, software version, fault status and measured values.
Filter efficiency, loading and regeneration
- P2002
- DPF efficiency below threshold, bank 1
- P2003
- DPF efficiency below threshold, bank 2
- P242F
- Diesel particulate filter: ash accumulation / restriction
- P2458
- DPF regeneration incomplete or too long
- P2459
- DPF regeneration too frequent
- P2463
- DPF: excessive soot accumulation
- P246C
- DPF severely restricted – power limited
Differential pressure and exhaust gas temperature
- P2452
- DPF differential pressure sensor A: circuit fault
- P2453
- DPF differential pressure sensor A: range/performance
- P2454
- DPF differential pressure sensor A: signal low
- P2455
- DPF differential pressure sensor A: signal high
- P2456
- DPF differential pressure sensor A: intermittent/erratic signal
- P244A
- DPF differential pressure too low, bank 1
- P244B
- DPF differential pressure too high, bank 1
- P244C
- Exhaust gas temperature too low for regeneration, bank 1
- P244D
- Exhaust gas temperature too high for regeneration, bank 1
A DPF code can result from filter loading, defective pressure hoses, the differential pressure sensor, temperature sensors, thermostat, injection or interrupted regenerations. The code family alone does not replace checking measured values.

QUESTIONS & ANSWERS
Well informed in advance.
What changes with DPF OFF?
Regeneration requests and DPF-related monitoring are deactivated in the engine management software. Associated faults and warnings therefore no longer occur.
How much does DPF OFF cost?
The price depends on the vehicle, control unit and access method. After checking the details, we provide a binding quote.
Can the vehicle be used on public roads afterward?
Deactivating emissions-related systems is generally not permitted on public roads. This service is intended for lawful export, motorsport, dynamometer and non-public-road applications; responsibility for actual use rests with the customer.
