Type Approved according to 94/20/EC/ECE-R-55. Detachable ball without vertical tool. Cannot be used for the S4 model. It is possible that the vehicle's engine cooling may not be sufficient for towing.

In this case, it may be necessary to replace certain parts of the cooling system. We are happy to help you check if your vehicle has the necessary preparations, please contact us with the chassis number in view. All necessary screws and fastening parts are included in the delivery.

Approval from Mines Service required. Depending on the vehicle model. General operating approval (ABE) and ECE - product certification (Homologation). Trailer hitches already approved according to ECE 55 or previously 94/20/E have already been tested according to European standards. They comply with CE directives, are tested and approved for the French market. It is not necessary to have the towbar approved by an expert or inspector after installation or to have it registered on the vehicle papers. What is the towable mass?

The towable mass defines the maximum total weight allowed, with which a vehicle equipped with a suitable towbar can tow a trailer. Depending on the type and version of the vehicle (engine power), this may vary. You can find the maximum authorized trailer load for your vehicle in your registration certificate. Where can I find this entry in the vehicle documents?

Depending on the age of the vehicle, you will find the value in the vehicle registration certificate. Take the value from area F. 3 and subtract it from the value from area F.

In order to calculate the maximum authorized towable mass for the vehicle. In exceptional cases, this value can be increased by calculation. Follow the instructions on the vehicle registration certificate - especially for slope indications. For the towbars we offer, you will find the maximum authorized trailer load of the trailer hitch in the technical data of the product view.

Important: If the maximum towing load value of the vehicle and the trailer hitch are not the same, the lower value always applies. Example: If a maximum authorized trailer load of 1,500 kg is indicated in the vehicle document, but the associated towbar has a tested trailer load of 1800 kg, only 1500 kg can still be towed. Under certain conditions, an increase in the trailer load may be requested for the vehicle.

This requires approval from the respective vehicle manufacturer such as Audi, BMW, Mercedes... The vehicle must then be presented to an expert.

With the test certificate you receive from them, you can have the change recorded in your vehicle documents at the registration office. The authorized trailer load in kilograms can be determined as follows: Formula for calculating value D: (Total weight Towable mass 9.81) / (Total weight + Towing capacity) Towable mass calculation formula: (value D total weight) / (total weight 9.81 - value D) Static mass calculation formula according to the 4% rule: Towable mass 0.04 GF = (authorized total weight of the vehicle in kg) see vehicle registration D = (value D in kN) see towbar nameplate/installation instructions.

What is a bumper cutout? When cutting out the bumper, a piece of the bumper is cut out on the rear part of the vehicle. It is important to note that there are bumper cutouts in both the visible and non-visible areas. This depends individually on the bumper design.

Trailer hitch brand manufacturers always strive to avoid bumper cutouts. If this is not possible, the cutout is limited to the bare minimum. If the bumper needs to be modified, you can always find it in the respective installation instructions of the item.

If a cutout is necessary, you will also find the dimensions or a template defining the size of the desired cutout. Tip: For cutting, use a jigsaw with a fine saw blade, as it allows you to work with plastic very easily and, above all, with precision.

To ensure that the cutting edges are smooth again, you can carefully heat them with a lighter. Professionals can also do this with a Bunsen burner or a "Blue-Fire". But keep a sufficient distance to be able to shape perfectly. The maximum weight that can be applied vertically from above on the towball of the trailer hitch. The authorized vertical load of the vehicle can be found in the vehicle manual under the "using a trailer" section. The maximum static mass of each towbar device is indicated on the approval plate and in the installation instructions. Tip: If you want to mount a rear bike carrier with an electric bike on your towbar, you must absolutely pay attention to a high static mass. Important: What if the vertical load values between the vehicle and the trailer hitch are not the same? Example: If the manufacturer has authorized a maximum vertical load of 75 kg for the vehicle, and the trailer hitch has an approved vertical load of 60 kg, the value of the towbar is decisive. In this example, it would be 60 kg.

In this case, the lower value always applies. This value of a trailer hitch is expressed in Kilo-Newton and serves as the basis for calculating the permissible trailer load.

The value D is determined and verified once and remains unchanged. Only the value D and the authorized vertical load are indicated on the trailer hitch approval plate.

The indication of value D allows determining the bandwidth during a modification reception according to § 19 (3) StVZO (German road traffic regulations). For example, it is possible to change the authorized total weight by varying the towed load accordingly, without a new inspection. The required value D according to directive 94/20/EC can be determined as follows: GF = (authorized total weight of the vehicle in kg) see vehicle registration GA = (authorized towable load of the vehicle in kg) see vehicle registration.

What is a foldable socket holder? The socket is mounted on a support plate with a hinge and can be folded under the bumper. It is not mandatory, but simply improves the visual appearance. Many detachable and swiveling towbars are equipped with retractable sockets.

We even have a few rigid towbars with this feature in our range. Info: The construction of a towbar device with a foldable socket holder depends on the presence of sufficient space between the cross tube of the towbar and the rear part of the vehicle.

Is a CT inspection required? Almost all trailer hitches in our range have an approval plate and are therefore checked according to the "94/20" directive. Such a towbar can be used on the public road without further expertise. According to Article 27, paragraph 1 of the StVZO (German road traffic regulations), a towbar retrofitted with an approval plate must only be added during the "next vehicle registration document check" at the registration office.

However, in accordance with clause 1a, any possible modification of the authorized towable load resulting from the installation of the towbar device must be reported without delay. After installing a towbar that requires an individual inspection at the technical inspection, we provide a certificate, with which you must have an individual inspection carried out after installation.

You will receive a document with which you must have an immediate registration on your vehicle papers at the registration office. National brand (M, F, N). The same procedures as for individual technical inspection apply here. The only difference is that these trailer hitches have a permanently assigned approval certification. Info: A towbar that has been tested according to EC94/20 meets the following criteria: - the towbar has a valid approval plate with all necessary data - the distance between the towball and the bumper and the road complies with the regulations.

The construction has passed the dynamic endurance test with 2 million load changes. All prescribed fastening locations by the vehicle manufacturer have been respected. Important: The installation instructions must be attached to the vehicle papers and must be in the vehicle! What is the installation time? The installation time of a towbar is indicated by the towbar manufacturer itself.

This time is limited exclusively to the installation of the product. This time does not take into account, for example, the installation or fitting of the bumper. Tips: To avoid calculation errors, calculate the specified indicative values with a factor of two. Experience shows that this comes closest to the actual installation time. What is a socket holder plate? The socket, whether 7 or 13 poles, is always attached to the socket holder plate with 3 screws. Some trailer hitches even come with a folding function. What is an approval plate?

Each towbar device must be equipped with an approval plate in order not to invalidate the vehicle's registration. An approval plate must contain the following information: - Towball diameter - Approval number - Serial or manufacturing data - Static mass kg - Value D in kN - Type Info: Do not hesitate to ask for the corresponding document. Disabling the rear fog light of the vehicle will not be possible. In Germany, flashing monitoring is mandatory for trailers.

If you want to order an electrical kit with a monitoring box, please contact us before purchasing. Compatible with additional kit for more permanence. More permanent integrated, pin 9.

Connection to the trailer socket. The socket allows connection to the trailer plug and ensures electrical connection between the car and the trailer. What does 7 pins mean? A simple connection that is sufficient to meet legal requirements. Like all 7-pin harnesses, special functions such as permanent power supply or reverse lights (on the trailer) are not possible.

What does 13 pins mean? This is a waterproof connector with simple handling. Meanwhile, this variant has become the standard for original equipment. Signaling functions and permanent power supply or reverse lights can be transmitted without any problem. Additional free pins are also available and offer useful options, especially in the camping area.

What is an original connector? The connections between the vehicle and the electrical kit are made using existing connectors, which excludes any connection errors. What is a diagnostics session? Modern electrical kits are equipped with trailer control modules capable of exchanging data with the vehicle's control units. Some functions, such as deactivating reverse sensors, trailer stabilization, and deactivating rear fog lights, only work when the two control units have learned to communicate with each other.

Therefore, a corresponding coding must be performed on the vehicle using a diagnostic tester. The current driving situation of the car is monitored by sensors installed on the vehicle. Once the trailer plug is connected, the vehicle recognizes the "trailer" operating mode and monitors all dynamic movements of the vehicle.

If the trailer ends up in a critical state, the vehicle's onboard computer helps the driver regain control of the situation. Info: - TSP, Trailer-Stability-Program - TSM, Trailer-Sway-Mitigation - TSA, Trailer-Stability-Assist Technical note: Trailer stabilization only works if supported by an electrical kit.

For this, the electrical kit must be registered in the car's data bus system through activation. Vehicles that do not have TSP as standard cannot be equipped with this function using a compatible electrical kit. What is a universal harness? A universal electrical kit is suitable for different brands and types of vehicles but is not adapted to any particular model. Characteristic features: - Connection is made to the power wires. The functions of each wire must be identified. The wiring must be shortened or extended if necessary. The installation instructions do not refer to vehicle-specific features. Tip: Whenever possible, always buy a vehicle-specific electrical kit, as installation errors are almost excluded. What is a specific harness?

A specific electrical harness has been specially developed for a particular vehicle. Before marketing a specific electrical kit, a test installation is carried out on the vehicle concerned to ensure its proper functioning. Typical features: - pre-designed connectors - exact cable lengths - installation instructions describe in text or pictograms all necessary work steps for correct installation. Info: There are vehicle-specific electrical kits that are also suitable for several vehicle models, as vehicles are often built on the same platform regardless of the manufacturer!

Advice: Specific electrical kits save installation time and therefore money. What does pre-assembled socket mean? One end of the cable harness is already connected to the socket. This facilitates installation and saves valuable installation time. What is a socket with screw terminals? The socket insert has connection locations for cable attachment, which establish contact through a screw terminal. What is a socket with crimp terminals? In the case of a crimp socket, the wires are already installed in the contact support. This results in a gas-tight compression of the cable with the contact plug, ensuring optimal contact connection. What is disabling rear fog lights? When disabling the fog light system, the rear fog lights of the towing vehicle are switched off. Regardless of whether the trailer has its own fog lights system. Note: When using a rear bike carrier with its own lighting units, it is mandatory that the rear fog light of the car is disabled (in Germany).

The Controller-Area-Network (CAN) data bus technique is the technical term for a special type of data transmission in a vehicle. It manages the electronic network of a modern automobile and connects the majority of control devices.

Info: A modern car contains up to 70 control units to exchange data between them, which then allow the most suitable functions. It is a bulb failure check that informs the driver, on the dashboard, by a visual symbol about a defective lighting, for example, turn signals, brake lights, etc. What is a turn signal relay or flasher relay? Turn signal relays also known as flasher relays have the function of transmitting the flashing impulse to the vehicle's turn signals or, if applicable, to the trailer's turn signals. In case of malfunction, the flashing frequency changes.

What is a trailer computer? The trailer computer partially or completely regulates the trailer lighting. The impulse usually comes from the vehicle's rear lights, which the control unit transmits to the trailer. What is a trailer detection? A trailer detection function indicates to the towing vehicle if a trailer or a bike carrier is connected.

This is often done through a microswitch integrated in the power socket. What is a C2 indicator? The C2 indicator is an additional green indicator. It must be placed on the dashboard, within the driver's field of view. Info: On certain vehicle types, a C2 indicator is already equipped to be controlled by the flasher relay. Practical: In trailer mode, the C2 indicator flashes at the same time as the standard turn signal indicator. Even without a trailer, it can flash up to three times, but then it must go off!

What is a wiring diagram? In the wiring diagram of a 7 or 13 pin socket, it is defined which cable occupies which contact of the socket. Cable identification is done by colors. The socket contacts are identified by numbers and letters. A microswitch is a small electrical switch integrated into the electrical kit socket.

It can be used for various functions such as disabling the EPH, trailer detection, etc. What is a central connector? Some vehicles are already prepared to receive a "factory electrical kit".

In such cases, there is one or more central connectors, which are ready to serve as connection points for the trailer cable set. What is a permanent power supply? The additional permanent power supply is a continuous 12Volt voltage that provides a continuous current to contact "no. 9" and is only possible for 13-pin trailer sockets according to DIN/ISO 11446. What is a charging cable?

A battery in the trailer can be charged with a charging cable while driving. This works via contact "no. 10", a 13-pin socket according to DIN/ISO 11446. As soon as the contact is cut, the power supply is interrupted by a cutoff relay. More offers for this type of trailer hitch. We distribute items from the following manufacturers.
