Frequently asked questions about Ahorn Camp motorhomes and services

The service center is located at Franz-Kirrmeier-Straße 21a in 67346 Speyer.

For capacity reasons, an appointment is absolutely essential.

If you do not live near our head office in Speyer, you can use the services of one of our partners throughout Germany. You can find them here. 

For an inspection, it is best to contact your local Renault partners.

The inspection must be carried out either after 2 years or after 40,000 kilometers. Whichever comes first.

The 17-digit number, consisting of letters and numbers, which is uniquely assigned to a vehicle on the chassis, can be found in column "E" in your vehicle registration document or on the driver's side of your windshield.

If the vehicle will not be used for a longer period of time (3 days or more), fully charge the battery and then disconnect the battery terminals on the quick release in order to completely disconnect the power supply. Alternatively, we can install a battery disconnect switch for you, simply contact us at service@ahorn-camp.de.

With Euro 6b, the alternator is active until the starter battery has reached the charge for restarting, after which the CAN bus switches off the alternator, meaning that the starter battery is no longer charged. As both batteries are connected in parallel when the engine is running, the body battery is also not charged. This can be remedied by a charge booster, which keeps the charge constant until the body battery is fully charged.

For vehicles with a first registration date up to August 31, 2017, the leak test must be carried out every 6 months on the date of first registration. For example, if your vehicle was first registered on January 7, 2016, the first leak test must be carried out by July 7, 2016. Each subsequent leak test must then be carried out 6 months later, i.e. 07.01. /07.07. /07.01 etc. This is the information from the manufacturer. For vehicles with a first registration date from September 1, 2017, the leak test must be carried out every 12 months on the date of first registration. In order to comply with these requirements, we recommend that our customers contact one of our service partner. 

During the leak test, certain points on the vehicle are checked for moisture and, if necessary, exterior flaps including the body door are adjusted, the hinges of the furniture caps and the rubber seals on the window and exterior flaps are checked.

The inspection must be carried out on the initial registration date + / - 14. If the inspection date is exceeded by more than 14 days, please bear in mind that the warranty will expire.

We recommend that you continue to have the checks carried out. However, the guarantee on tightness has expired.

Yes, we also rent out motorhomes and campervans through our rental brand Ahorn Rent. We now have up to 60 rental stations throughout Germany. Here you can easily create a Maple rental partner in your area.

In this case, you will need a larger solar charge controller. This must therefore be replaced, but is included in the retrofit price.

Please avoid deep discharging your vehicle's batteries, as this could damage them. We recommend checking the battery indicator regularly. Charging should be carried out at the latest when the battery indicator shows three bars. The batteries should never have less than 11.9 V. However, if the battery is almost completely discharged, disconnect it and connect the vehicle to shore power. The battery must be disconnected during the winter break and if the vehicle is parked for more than 3 days. If the vehicle is parked for longer periods, we also recommend regular charging in between.

The frost protection monitor is generally installed in the heating area or in the kitchen cupboard of your motorhome. The only exception to this is the Ahorn Camp T640, where the frost monitor is located behind the driver's seat. It is a small black box the size of the palm of your hand with a light blue button and a light blue lever.

The frost protection guard may be open here. This must be closed in order to fill the tank. To do this, the blue button must be pressed in and the lever positioned crosswise.

The front passenger airbag can be deactivated in all Ahorn Camp motorhomes. To do this, you must set the On-Off switch on the right-hand side of the airbag to Off.

To increase the air spring pressure of your motorhome, press and hold the switch in the center of the control panel. To reduce the air spring pressure / for less air, you must press the valves on the left and right individually.

After the body battery has been disconnected for a while, for example after the winter break, your Truma heater may show error code E621 on the display the first time it is switched on. Wait 15 minutes until this message stops flashing, then this error must be acknowledged by simply pressing the rotary/push button on the CP Plus and the heater should work as usual again. If the control panel is in standby mode, the backlight must first be activated by simply pressing it before the message can be acknowledged with a second press.
