Detachable ball without vertical tool. Not compatible with S4 and RS4 models.

All necessary screws and fixing parts are included in the delivery. Approval from Mines Service required. General Operating Approval (ABE) and ECE - product certification (Homologation). Trailer hitches that are already approved according to ECE 55 regulation 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 tow bar 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 tow bar 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 section F.

3 and subtract it from the value in section 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 tow bars we offer, you will find the maximum authorized trailer load of the trailer hitch in the product view technical data. Important: If the maximum towing load value of the vehicle and the trailer hitch are not identical, the lower value always applies. For example: If a maximum authorized trailer load of 1,500 kg is indicated in the vehicle document, but the associated trailer hitch has a tested trailer load of 1800 kg, only 1500 kg can be towed.

Under certain conditions, an increase in the trailer load can 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 entered 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). Formula for calculating the towable mass: (value D total weight) / (total weight 9.81 - value D). Formula for calculating total weight: (value D trailer load) / (trailer load 9.81 - value D). Formula for calculating the static mass 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 tow bar nameplate/mounting instructions. What is a bumper cutout?

During the bumper cutout, a piece of the bumper is cut on the rear part of the vehicle. It is important to note that there are bumper cutouts in the visible and non-visible area. 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 that defines the size of the desired cutout. Tip: For the cutout, use a jigsaw with a fine saw blade, as it allows you to work with plastic very easily and especially with precision. So that the cutting edges are smooth again, you can carefully heat them with a lighter. Professionals can also do it with a Bunsen burner or a "Blue-Fire".

But keep a sufficient distance to be able to shape perfectly. What is the static mass? The maximum weight that can be applied vertically from above on the trailer hitch ball. The authorized vertical load of the vehicle is found in the vehicle manual under the point "trailer use". The maximum static mass of each tow bar device is indicated on the approval plate and in the installation instructions. Tip: If you want to mount a rear bike rack with an electric bike on your tow bar, you must absolutely pay attention to a high static load. Important: What if the vertical load values between the vehicle and the trailer hitch are not identical? For 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 hitch value 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 checked 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 the determination of the bandwidth during a modification reception according to § 19 (3) StVZO (German road traffic regulations).

For example, the authorized total weight can be modified by varying the towed load accordingly, without a new inspection. The required value D according to directive 94/20/CE can be determined as follows: GF = (authorized total weight of the vehicle in kg) see vehicle registration GA = (authorized trailer 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 an improvement in visual appearance. Many detachable and swiveling trailer hitches are equipped with retractable sockets. We even have some rigid tow bars with this feature in our range. Information: The construction of a trailer hitch device with a foldable socket support plate depends on the presence of sufficient space between the cross tube of the tow bar and the rear part of the vehicle. Is a CT registration necessary?

Almost all trailer hitches in our range have an approval plate and are therefore tested according to the "94/20" directive. Such a tow bar can be used on the public road without further expertise.

According to article 27, paragraph 1 of the StVZO (German road traffic regulations), a trailer hitch retrofitted with an approval plate should only be added during the "next vehicle registration consultation" at the registration office. However, according to clause 1a, any possible modification of the authorized trailer load resulting from the installation of the tow bar must be reported promptly. After installing a trailer hitch 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 terms as for the individual technical inspection procedure apply here. The only difference is that these trailer hitches have a permanently assigned approval certification. Information: A trailer hitch that has been tested according to EC94/20 meets the following criteria: - the trailer hitch has a valid approval plate with all necessary data - the distance between the ball and the bumper and the road surface complies with regulations. The construction has passed the endurance test with 2 million load changes.

All prescribed fastening points 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 trailer hitch is indicated by the tow bar 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 support plate? The socket, whether 7 or 13 poles, is always attached to the socket support plate with 3 screws. Some trailer hitches even have a folding function.

What is an approval plate? Each tow bar 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: - Tow ball diameter - Approval number - Serial or manufacturing data - Static mass kg - Value D in kN - Type Information: Feel free to ask us for the corresponding document. Not compatible with bike racks.

Disabling the rear fog light is not possible. In Germany, a flashing control unit is mandatory for trailers.

If you wish to order an electrical kit with a flashing control unit, please contact us before purchasing. More permanently integrated, pin 9. Connection to the trailer socket. The socket allows you to connect to the trailer plug and ensures the 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.

In the meantime, 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 prevents any wiring errors. What is a diagnostic tool required? Modern electrical kits are equipped with trailer control modules capable of exchanging data with the vehicle's control units. Some functions, such as disabling the reverse sensors, trailer stabilization, and turning off the rear fog lights, only work when both 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. Information: - TSP, Trailer-Stability-Program - TSM, Trailer-Sway-Mitigation - TSA, Trailer-Stability-Assist Technical note: Trailer stabilization only works if an electrical kit assists it. For this purpose, 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 an electrical kit compatible with TSP. What is a universal harness? A universal electrical kit is suitable for different vehicle brands and types, but is not suitable for any specific model. Characteristic properties: - Connection is made to the feeding wires.

Each wire's function must be identified. The wiring must be shortened or lengthened if necessary.

The installation instructions do not refer to vehicle-specific characteristics. Tip: Whenever possible, always buy a vehicle-specific electrical kit, as assembly errors are almost excluded. What is a specific harness? A specific electrical harness has been specially developed for a specific vehicle. Before marketing a specific electrical kit, a fitting test is carried out on the respective vehicle to ensure its proper functioning. Typical properties: - Pre-designed connectors - Exact cable lengths - The installation instructions describe all necessary work steps in text or pictograms. Information: 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 assembly 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 slots for cable fastening, which make 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 carrier. This results in a gas-tight compression of the cable with the contact plug, ensuring an optimal contact connection. What is disabling the rear fog lights?

When disabling the fog light system, the rear fog lights of the towing vehicle are turned off. It doesn't matter if the trailer has its own fog light system.

Note: When using a rear bike rack 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 technology 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. Information: 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 indicates to the driver, on the dashboard, with a visual symbol, a faulty lighting, e. turn signals, brake lights, etc.

What is a flasher relay or turn signal relay? Flasher relays are also called turn signal relays and are used to transmit the flashing impulse to the vehicle's turn signals or, if applicable, to the trailer. If there is a malfunction, the flashing frequency changes.

What is a trailer computer? The trailer computer partially or completely regulates the lighting of the trailer. The impulse usually comes from the rear lights of the vehicle, which the control unit transmits to the trailer. What is a trailer detection? A trailer detection function indicates to the towing vehicle whether a trailer or a bike rack is attached. This is often done by means of a microswitch integrated into 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 vision. Information: On certain types of vehicles, a C2 indicator is already equipped to be controlled by the turn signal 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 must go out! What is a wiring diagram? In the wiring diagram of a 7 or 13-pole 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 that is integrated into the electrical kit socket. It can be used for different functions, for example: 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 harness.

What is a permanent power supply? The additional permanent power supply is a continuous 12Volt voltage that provides a permanent 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 off, the power supply is interrupted by a cut-off relay. More offers for this type of trailer hitch. We distribute items from the following manufacturers. Even more reasons to order from TS24. Our experienced staff will be happy to advise you.
