Parts Identification

Finding parts matching the vehicle

As one of the key functions, the ProKat® system provides an identification of original and aftermarket parts as well as the associated work values.

Vehicle Identification

The starting point for the determination is an accurate identification of the vehicle. To this end, either a VIN enquiry (subject to a fee at a usual market price) or context-specific enquiries can be used.

Context-specific means that only such questions are asked that are necessary for finding the respective parts. Thus, if an oil filter is being looked for, questions about the engine will be asked, if any. If brakes are being looked for, the diameter of the discs will be required.

For the compilation of the further enquiries, known vehicle details such as the German Federal Office for Motor Vehicles (Kraftfahrt-Bundesamt) key codes, engine code or time of manufacture can be used, whereby some questions can be left out or the possible answers at least be limited.


The result of the enquiry is the original parts incl. price (RRP) and necessary accessories where applicable (equally OE parts) as well as the associated work values.

The determination of the work values observes the fact that individual tasks that are necessary for Part A are not included again for Part B: The wheel is only dismounted once to change the brake disc and pad.

Subsequently, the products of the aftermarket can be determined via the original parts found. 

There are two ways of doing this:

  1. Finding all referencing products for the customer to choose the desired product
  2. The selection of a product by the system per required OE part to create a calculation or offer

In the second case manufacturers and prices can be prioritised. The selection of the products can then also be of a more complex nature to present differentiated approaches in the aftermarket, predominantly when putting together sets.

Repair packages

The ProKat system facilitates the definition of packages as a basis of calculations and offers for repair and maintenance needs.

These packages enable a quick introduction to the most important subjects, thus in particular topics of wear and tear such as brakes, toothed belts or battery and the highlighted visual presentation associated with that.

Furthermore, this way, different parts and tasks that belong to the needs of repair can be combined. When it comes to brakes for example, packages are offered per axle for finding out the brake discs or drums, the matching pads or shoes, as well as wear and tear sensors.

Even more complex logics for vehicle-specific differences can be realised. It is common, for example, to also replace the water pump when changing the toothed belt due to high amount of work involved, insofar as it is also driven by the toothed belt. If the water pump is driven by the V-belt, however, it is not replaced.

Repair calculations

A full calculation can be drawn up on the basis of the general parts and work assessment as well as the definition of repair packages.

In the case of parts, the specific products of the aftermarket are selected via a general selection of the manufacturers as well as a specific prioritisation (e.g. location or partner) of the same. The providers can, for example, be limited to ATE, Brembo, Textar and Bosch and it can also be determined which manufacturer of these are to be used first, second and so on.

A further defined narrowing down within a manufacturer is also possible. Product lines, for example, from the field of tuning/sports can be ruled out as well as, in the last instance, a decision can be made about the price.

The result is specifically selected aftermarket parts which, in connection with an hourly rate, can lead to an overall calculation.

Review & order verification

With the help of the ProKat® system, you can check whether selected parts or even parts from a selected product group match the customer vehicle or not.

This is possible as early as during the order process, by filtering display lists, in the shopping baskets or even subsequently for orders that have already been submitted.

In this case, besides using the OE part reference information, an additional review of product properties is applied. This way, products where the OE part reference is missing can also be checked.

A shop system that is based on the filtering of products via the selection of a TecDoc vehicle (TecDoc KType) can thus be ideally complemented. Via our interface for inputting order data, a downstream order verification is also possible even without changes to the existing shop system.
