Processing of diesel particulate filter cleaning

Handling Process

General information on processing:

The prerequisite for cleaning is that the diesel particulate filter (DPF) is in a technically perfect condition that is:

  • the ceramic insert must not be broken, cracked or fused.
  • the filter must not have any deep dents, holes or rust through.

In addition, all sensors, pressure and temperature sensors, hoses, holders, clamps and other attachments must be removed for cleaning. We accept no liability for attachments that have not been dismantled! And we cannot give any warranty/refund on the functionality of sensors removed by us! In addition, additional costs may be incurred for the removal of sensors carried out by us!

Please indicate in our order form any self-cleaning tests or treatments with chemical additives that may have been carried out.

TIPP from the expert:
The catalytic converter must be cleaned as well! Otherwise the diesel particulate filter may clog up again.

1. Removal

Remove your diesel particulate filter and, if present, the pre-assembled catalytic converter and remove the attachments.

2. Fill in the form

Please fill out our order form and enclose this printed out with your parcel so that the filters can be allocated correctly.

3. Send filter

The easiest, fastest and cheapest way to send your package to us is with our UPS shipping.

After filling out the order form and selecting Parcel label, you will receive your label by e-mail. Please print it out and stick it on the package and bring it to a UPS Access Point near you.

This cost for the outward shipment is 35,- Euro incl. VAT and will be calculated together with the DPF cleaning.

Please pay attention to the package dimensions! Oversizes will incur additional costs. You can use our package calculator to check the package dimensions.

The belt dimensions and additional costs can be found in the order form under Parcel label.

Of course you can also send your parcel to us yourself. Please note that the delivery time can take several days depending on the shipping method and provider.

During our opening hours you can also deliver filters personally or deposit them in our depobox after phone consultation.


4. Entrance

As soon as your diesel particulate filter arrives, we check that the ceramic and the housing are in order. Then your diesel particulate filter will be checked and the measured data recorded in our log. Each filter then receives an identification number for assignment. You will then receive an e-mail regarding the receipt and condition of your diesel particulate filter. In addition, this e-mail is attached to our invoice / payment information. You are welcome to send us a proof of payment of the transfer as proof or you have the possibility to pay directly via PAYPAL. We clean car filter (diesel particulate filter) for private customers only in advance. Please understand that we can only send cleaned filters after receipt of payment!

5. Cleaning

The filters cleaned by us are cleaned so long and so often, until they are freed to approx. 98% of the soot and ash residues and have reached the reference value for the respective filter type. For this several cleaning processes are necessary.

The cleaning time therefore depends on the degree of contamination of the filter. In general, we need approx. 1-3 working days (Monday to Friday) for cleaning, but on average 80% of the filters are cleaned within 24 hours. In the process developed and applied by us, the filters are treated in such a way that neither the ceramic nor the housing are attacked.

After successful cleaning, the filter is checked again and the measured values are recorded in our test report.

If your filter cannot be cleaned, you will not incur any cleaning costs.

6. Guarantee

We give a 6-month guarantee on our cleaning performance.

7. Return shipment

Once the diesel particulate filter has been cleaned and your payment has been received, we will return your filter to you. The return shipment is already included in the price. Your documents such as invoice, test report and installation instructions are enclosed with the package. We will also send you all documents and the shipping notification by e-mail.

The packages are insured up to 3.000 Euro.

8. Installation

The installation and removal of a diesel particulate filter is time-consuming and should be carried out in a workshop, since after the installation of the cleaned filter all sensors, hoses, screw connections and the EGR valve must be checked for operability. In addition, the ash value with respect to the DPF must be reset in the engine electronics. A simple deletion of the fault in the fault memory is not sufficient here and can result in the DPF causing a fault again after a short time and requiring renewed cleaning. Please pay attention to the installation instructions enclosed with the parcel!
