Technical data -> Repairs and technical modifications for Your Volkswagen T-Roc SUV First Generation (2017-2025)

Incorrect installation of number plate holders with trim frames or number plates can damage components, e.g. cables or sensors.  
Always ask a suitably qualified workshop whether installation of a number plate or number plate holder with trim frame is possible  
for your vehicle. Volkswagen recommends using an authorised Volkswagen repairer.  
The number plate holder with trim frame is used for mounting the official number plate.  
The radar sensor can be installed either below the number plate or behind the Volkswagen badge. The number plate or the Volkswagen  
badge can impair the view of the radar sensor in the front area. Therefore, mount the number plate at a sufficient distance from the  
radar sensor or only operate the vehicle with the original Volkswagen badge or a badge approved by Volkswagen.  
Damage in the area of sensors and cameras  
WARNING  
If the area around sensor and cameras is damaged, e.g. by stone chips or impacts when parking, this can prevent the driver assist  
systems from functioning correctly. Failure of the driver assist systems can lead to accidents and cause serious or fatal injuries.  
Have the component replaced by a suitably qualified workshop in the event of damage in the area of the sensors and cameras.  
Volkswagen recommends using an authorised Volkswagen repairer.  
After replacement of components, the sensors and cameras may have to be adjusted and calibrated by a suitably qualified workshop.  
Volkswagen recommends using an authorised Volkswagen repairer.  
If the windscreen has been damaged in the viewing field of the sensors and camera, e.g. by stone chips, the windscreen must be  
replaced. Repair of the stone chip damage can lead to malfunctions or functional faults in the driver assist systems. After replacing the  
windscreen, the cameras and sensors must be adjusted and calibrated by a suitably qualified workshop. Volkswagen recommends  
using an authorised Volkswagen repairer.  
.
Unauthorised modifications to the electronic components or software in the vehicle may cause faults. As the electronic components  
are linked together in networks, these faults may indirectly affect the working of other systems. This can seriously impair vehicle  
safety, lead to excessive wear of components and also invalidate the type approval for the vehicle.  
The authorised Volkswagen repairer cannot be held liable for any damage caused by technical modifications and/or work performed  
incorrectly.  
The authorised Volkswagen repairer is not responsible for damage caused by technical modifications and/or work performed  
incorrectly. Such damage is not covered by the Volkswagen guarantee.  
Have all repairs and technical modifications carried out by a suitably qualified workshop. Volkswagen recommends using an authorised  
®
Volkswagen repairer that supplies Volkswagen Genuine Parts .

Diagnostic interface (OBD)  
There is a diagnostic interface in the vehicle interior for reading the event memories (OBD). Event memories document any errors that  
have occurred and any deviations from the nominal values in the electronic control units  
.
The diagnostic interface (OBD) is located in the footwell on the driver side underneath the dash panel, or behind a cover next to the  
bonnet release lever.  
The event memory should only be read and reset by a suitably qualified workshop. Additional information on the stored data is  
available from suitably qualified workshops. Volkswagen recommends using an authorised Volkswagen repairer.  
After a fault has been rectified, the information in the event memory relating to the fault is deleted. Other memory content is  
overwritten on an ongoing basis.  
Vehicles with special auxiliary equipment or body parts  
Auxiliary equipment and second stage manufacturers must ensure that the equipment and bodies (conversions) adhere to the  
stipulated environmental laws and regulations, particularly the EU directive 2000/53/EC concerning end-of-life vehicles and EU  
directive 2003/11/EC concerning the restriction on the marketing and use of certain dangerous substances and preparations.  
The vehicle owner must keep all assembly documentation for these conversions and pass it on to the scrapping company upon vehicle  
handover if the vehicle is scrapped. This is intended to facilitate environmentally responsible disposal for all vehicles, including refitted  
vehicles.  
Engine and transmission guard  
An engine and transmission guard can reduce the risk of damage to the vehicle’s underbody and sump, for example when driving over  
kerbs, drive entrances or unsurfaced roads.  
Have retrofitting carried out by a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.  
An engine and transmission guard may not be available in all countries.  
WARNING  
Incorrect repairs and modifications to the vehicle can impair the effectiveness of the driver assistance systems and the airbags when  
they trigger. This can cause malfunctions and lead to accidents and serious or fatal injuries.  
Have repairs and modifications to your vehicle carried out only by a suitably qualified workshop. Volkswagen recommends using an  
authorised Volkswagen repairer.  
WARNING  
Incorrectly performed repairs and modifications on the vehicle, e.g. through use of unsuitable parts, can damage the vehicle and  
cause accidents and serious or fatal injuries.  
Never fit parts to your vehicle that differ in their design or characteristics from the factory-fitted parts.  
Use only wheel rim/tyre combinations that have been approved by Volkswagen for your vehicle type. More detailed information is  
available from a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.  
Have repairs and modifications to your vehicle carried out only by a suitably qualified workshop. Volkswagen recommends using an  
authorised Volkswagen repairer.  
Volkswagen recommends the use of Volkswagen Genuine Parts or Volkswagen Genuine Accessories. These parts and accessories  
have been specially tested by Volkswagen for suitability, reliability and safety.  
WARNING  
Use of the diagnostic connection for other than its intended purpose can cause malfunctions and lead to accidents and serious or  
fatal injuries.  
Never read the event memory yourself using the diagnostic interface.  
Never upload data to the vehicle yourself using the diagnostic connection.  
The event memory should be read only by a suitably qualified workshop using the diagnostic connection. Volkswagen recommends  
using an authorised Volkswagen repairer.  
.
Modifications and repairs to the front bumper, the doors, the front seats, the roof or the bodywork should only be carried out by a  
suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer. System components and airbag  
system sensors might be fitted on these vehicle components.  
If you work on the airbag system or remove and install parts of the system when performing other repair work, parts of the airbag  
system may be damaged. The consequence may be that, in the event of an accident, the airbag inflates incorrectly or does not inflate  
at all.  
Regulations must be observed to ensure that the effectiveness of the airbags is not reduced and that removed parts do not cause any  
injuries or environmental pollution. These requirements are known to suitably qualified workshops. Volkswagen recommends using an  
authorised Volkswagen repairer.  
Any modifications to the vehicle’s suspension could prevent the airbag system from working properly during a collision. For example,  
using wheel rim/tyre combinations that have not been approved by Volkswagen, lowering the vehicle or making modifications to the  
suspension rate including work on the springs, struts and shock absorbers etc., could change the forces that are measured by the  
airbag sensors and sent to the electronic control unit. Some changes to the suspension could cause the forces measured by the sensors  
to increase, for example. This can lead to the airbag system being triggered in collision scenarios where it normally would not be  
triggered if modifications to the suspension had not been made. Other modifications can cause the forces measured by the sensors to  
decrease, therefore preventing the airbag system from being triggered when it should have been.  
WARNING  
Use of unsuitable replacement parts and accessories can cause malfunctions and damage to the vehicle and impair the effectiveness  
of the airbag system. This also applies to work, modifications and repairs that are not performed correctly. This can lead to vehicle  
damage and accidents with serious or fatal injuries.  
Have repairs and modifications to your vehicle carried out only by a suitably qualified workshop. Qualified workshops have the  
necessary tools, diagnostic equipment, repair information and qualified personnel. Volkswagen recommends using an authorised  
Volkswagen repairer.  
Please note that the airbag unit cannot be repaired, but must be replaced.  
Never install recycled airbag components or components that have been taken from end-of-life vehicles in your vehicle.  
Never fit parts to your vehicle that differ in their design or characteristics from the factory-fitted parts.  
WARNING  
Modification of the vehicle suspension, including the use of non-approved wheel rim and tyre combinations, can change how the  
airbag functions. This can result in serious or fatal injuries in the event of an accident.  
Never install components in the suspension system which do not have the same characteristics as the original factory-fitted  
components.  
Use only wheel rim and tyre combinations that have been approved by Volkswagen for your vehicle type. More detailed  
information is available from a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.  
Electromagnetic radiation  
If a mobile telephone or radio device is used without being connected to the external aerial, the electromagnetic radiation will not be  
optimally directed to the outside of the vehicle. Increased levels of radiation in the vehicle interior may occur in areas with poor signal  
in particular, for instance in rural areas. This could constitute a health hazard →  
.
Depending on the vehicle’s equipment level, a suitable mobile phone interface can be used to connect the mobile telephone to the  
external aerial. The connection quality is improved and the range is increased.  
Using the telephone  
®
Many countries require a hands-free system to be used when using a telephone inside the vehicle, e.g. via a Bluetooth connection.  
Before use, secure the mobile telephone to a suitable bracket →  
or stow it in a storage compartment so that it cannot slip around,  
e.g. in the centre console.
