## Why this one

- **No filter removal**: Applied through the sensor port with the filter still fitted.
- **Workshop tool system**: Used with DPF pressure gun 7946 and probe 7945.
- **Loosens hard deposits**: Dissolves hardened, dense and encrusted deposits on the filter surface.
- **Passenger-car DPF/FAP**: For passenger-car diesel engines with particulate filters.

## On the job

### In-place cleaning

Short-trip city cars often block their particulate filter long before the service is due. With the filter below 40 °C, the workshop removes the temperature or pressure sensor, feeds the Pro-Line spray probe into the filter with the DPF pressure gun and sprays the cleaner onto the loaded surface. The fluid dissolves hardened, dense and encrusted deposits.

### Before you start

Check where the filter sits: on some cars it is close to the manifold or turbo, and no fluid may reach the combustion chamber through an open exhaust valve. Wear gloves and eye protection, since it irritates skin and eyes. Afterwards depressurise the gun and drain its tank completely before storing it.
