VW, Audi, BMW & Mercedes
Common diesel DPF warnings, limp mode and regeneration faults checked with live data before any software work.
DPF Fault Investigation & Software Support
Support for vehicles with repeated DPF faults, blocked filter warnings, limp mode, pressure sensor faults or regeneration-related issues — investigated properly before any software work is considered.
Fault investigation first. Some emissions-related software work may be suitable only for off-road, motorsport or export use where applicable. The customer is responsible for road legality and emissions compliance.
DPF Fault Support
Common symptoms from DPF faults
- DPF warning light staying on or flashing
- Vehicle stuck in limp mode
- Failed or repeated forced regenerations
- DPF pressure sensor fault codes
- Smell of fuel or unusual smoke after a regen attempt
Our process
What we check before programming
STEP 01
Diagnose the root cause
We read fault codes and live data to understand why the DPF is struggling, rather than jumping straight to software.
STEP 02
Inspect filter and sensor condition
Where possible, we check whether the DPF itself, its sensors, or related components are the underlying problem.
STEP 03
Software support where suitable
If software support is the appropriate route for your intended use, the limitations and compliance responsibilities are explained clearly first.
STEP 04
Verify and road test
Codes are cleared, the vehicle is road tested, and you're told exactly what was done.
DPF work is supplied for fault investigation and software support. Some emissions-related software work may suit off-road, motorsport or export use only where applicable. Changes to DPF software can affect NCT (roadworthiness test) results and emissions compliance — the customer is responsible for ensuring any work carried out meets the legal requirements for how the vehicle is used.

Information to send before booking
These details help confirm the correct route before vehicle attendance, ECU posting or donor ECU purchase.
- Vehicle registration, make, model, year and engine size
- DPF fault codes, soot loading information if available and dashboard warnings

- Intended vehicle use, because some software options may suit off-road, motorsport or export use only
FAQ
Questions about DPF fault support
Will DPF software work affect my NCT?
It can. Emissions-related changes may affect NCT results, so we'll talk through your specific situation and intended use before any work goes ahead — compliance is the vehicle owner's responsibility.
Can a blocked DPF be cleaned instead?
In some cases, yes. We always investigate the actual fault first, since cleaning, sensor repair or a forced regeneration may resolve the issue without needing a software change.
What causes repeated DPF faults?
Short journeys, sensor faults, EGR problems and oil dilution are common causes. Diagnosing the real cause is the first step before deciding on the right fix.
