We provide a 6-year water ingress warranty independent of the manufacturer’s warranty. It is also valid from the day the vehicle is handed over to the customer, but no later than 18 months after the factory ships the vehicle to the dealer.

Yearly fee-based leak inspections are mandatory for this warranty to be valid. They must be performed by a Dethleffs servicing partner or dealer within a time frame of +/- 6 months of the anniversary of the first registration date or the receiving date (see effective date of the warranty). The entries in the service book with adhesive stamps and the entries on our online warranty portal are proof that the inspections have been performed. The prerequisite for the warranty is that the vehicle’s mandatory inspections must always be performed on time. The water ingress warranty is invalidated if the inspections are not performed on time. Please refer to the manual in the vehicle for the specific terms and conditions.     I.e. No stickers  and signature in your book on the service record, measons b. 
In general, a water ingress claim is processed as follows:

The vehicle must be sent to a specialist, an authorised Dethleffs servicing partner or dealer, for inspection. If a genuine leak is found when the inspection has been performed correctly according to the manufacturer’s specifications, the Dethleffs servicing partner or dealer will contact us to discuss how to proceed. The Dethleffs servicing partner or dealer will usually receive prompt approval to commence the repairs so that the repairs are completed in a timely manner in accordance with the water ingress warranty. The water ingress warranty applies to water entering the vehicle from outside.

The water ingress warranty solely involves specialist repair. Claims for deterioration or for refunds for faulty goods as well as travel costs or other indirect costs are excluded from this warranty.
