No. Fitting a City-Filter® does not affect any statutory warranty coverage or extended guarantee provided by the vehicle manufacturer. No other warranty conditions would be compatible with the current motor vehicle block exemption regulation. This decision was reached by both the Bundeskartellamt (Federal German Monopolies Commission) and the European Commission. All model variants of HJS City-Filter® are tested by TÜV. The Kraftfahrt-Bundesamt (German Federal Motor Transport Authority) then issues the national type approval required under EU regulations. This is a guarantee that all the technical and tax-related requirements have been fulfilled.
