Cleaning the particle filter in the car
Cleaning a particle filter is much cheaper than replacing the filter. If you are skilled at handwork, you can even do this work yourself.
What you need:
- Cleaning set for particle filters
Frequent short journeys in particular can lead to blockages in the particle filter. This is because the temperature required for self-cleaning is not reached. As a rule, this then means that the filter has to be replaced with a new one. In the meantime, however, there is also the option of cleaning the particle filter.
How to clean a particulate filter
- The Tunap company from Wolfratshausen has developed a patented cleaning agent for cleaning particle filters. You can get this in various Online shops or in the auto accessory trade.
- With a little manual skill, you can apply it yourself and don't necessarily need one workshop to seek out.
- First you need the temperature and pressure sensors on the Exhaust dismantle. The cleaning agent is sprayed into the particle filter with a probe that is included in the scope of delivery of the cleaning set. For the detergent to work effectively, you should spray for 5 seconds at a time and then take a break of 5 seconds. This way you have to spray the entire contents of the bottle.
- Then you have to spray in the rinsing concentrate contained in the cleaning set in the same way. This loosens all the soot particles that had settled.
- After cleaning is complete, you must reassemble the sensor. You have to be careful when doing this so that the sensor is not damaged.
- Immediately after cleaning, you must drive your car for at least 20 minutes so that the temperature required for self-cleaning is reached. Therefore, you should preferably drive on federal highways or motorways. The required temperature cannot be reached when driving in city traffic.
