SEIKEL warranty certificate via product registration

When purchasing and installing a SEIKEL product, you need a warranty certificate so that we can cover the costs in the event of a warranty claim. You can download this here and fill it out and send it back to us. The certificate is valid for both commercial and private customers.

German TÜV confirmations and parts certificates

SEIKEL underbody protection plates

The installation of SEIKEL underbody protection panels on the various Volkswagen commercial vehicle models has been tested in an exemplary manner by the German TÜV Süd, Munich. This means that our protective plates do not require any further approval in Germany, subject to compliance with all conditions as required in the German TÜV confirmation. When installing SEIKEL products outside of Germany, we recommend that you check the validity of the German documents in your country in advance. Please note: Only the parts certificates for suspensions are bilingual in German/English (document initial: de/en).


SEIKEL chassis, chassis parts, snorkel and rope winches

Retrofitting these products interferes with the vehicle geometry and/or the engine function and thus constitutes a conversion, after which the vehicle no longer complies with the ECE papers.

To ensure that the vehicle’s operating licence does not expire after the conversion, various rules and regulations must be observed in Germany. When installing SEIKEL products outside Germany, we recommend that you check the validity of the German documents in the respective country in advance. Below you will find our parts certificates by vehicle type.
