Filters must be changed regularly

Bosch recommends your filters are checked before long vacation trips

Filter check of the vehicle inspection before the trip to the summer vacation — Relax and enjoy your vacation - with the security of reliably functioning filters in your car.

Checking filters is part of any vehicle inspection before summer vacation.

If the change interval specified by the vehicle manufacturer has been reached, a new filter must be installed. If the scheduled change of a filter is due soon after the vacation, Bosch recommends bringing this change forward. A new filter can reduce the load on the vehicle systems and components, especially over long distances. In addition, a new cabin filter will provide improved comfort on long journeys and supports the proper function of the air conditioning system.

How often a filter has to be changed?

Information on how often a filter must be replaced can usually be found in the vehicle's service booklet. These change intervals are specified by the respective vehicle manufacturers. On newer vehicles, the filters are usually changed as part of the specific service. If you have any questions about changing the filter, the workshop can advise.
