Question 1

What is the difference between an audit order and an expert opinion?

Accepted Answer

A test order provides a technical measurement report on the VTG function. An expert opinion further contextualizes this measurement result from a legal perspective and is intended for automotive experts and lawyers in case of disputes.

Question 2

What distinguishes a VISCOM report from a classic vehicle expert report?

Accepted Answer

A standard vehicle inspection report is primarily based on visual and endoscopic examination. VISCOM supplements this with reproducible measurement data from its own flow bench regarding the actual VTG function — as technical support, not as a replacement for the standard vehicle inspection report.

Question 3

Who are the expert reports intended for?

Accepted Answer

Especially for automotive experts and lawyers who, in case of dispute, need a reliable technical measurement basis for the VTG function of a turbocharger, but do not have their own flowbench.

Question 4

Does VISCOM also offer turbocharger parts for classic and vintage cars?

Accepted Answer

Yes. For turbochargers with variable turbine geometry, which have been installed since the late 1990s, VISCOM manufactures discontinued (NML) components such as compressor wheels and housings and then tests them on its own flowbench.

Question 5

Are the manufactured parts compliant with regulations?

Accepted Answer

Each manufactured component undergoes functional testing on a VISCOM flowbench. Inquiries are individually reviewed for feasibility, delivery time, and required testing scope.

Question 6

Is there a fixed product range, or are parts only manufactured on request?

Accepted Answer

This offer will only be processed upon request. Specifically:Result: A component functionally tested on the VISCOM Flowbench.Probability of success: Manufacturing via the patented CNC partner plus in-house calibration, the same combination as with the Flowbench systems.Time: Initial feasibility and delivery time estimates are usually provided within a few working days of request.Effort required: A photo or drawing of the required part is sufficient for an initial assessment. A fixed product range is planned for a later expansion phase, once recurring component types become apparent.

Your turbocharger put to the test.

1. Send in your turbocharger or schedule an on-site appointment
