Challenging a vehicle report: when it is worth it

To challenge a vehicle report (Gutachten) means to have its findings checked by an expert. These are the findings on repair costs, diminished value (Wertminderung) and residual value (Restwert). Residual value is the sale value of the damaged vehicle. In practice, this is usually not about someone else's report. It is the opposite case. The other party's insurer has your report recalculated and reduces individual items (Kürzung). The two cases work differently. In both, an independent vehicle expert provides the technical basis, and a lawyer pursues the claim.

Was your report reduced? Send us the insurer review report (Prüfbericht). In the free initial assessment, we check whether the removed items are justified in the report. Call us at 09131 91 66 143 or write to us.

What are the two situations?

First find out which of the two cases applies to you:

Important to know: An insurer review report is not a second report. It is usually made without inspecting the vehicle, only at a desk from the data sent, and it shows the view of one party.

Which items are reduced most often?

The reductions repeat. It is almost always the same six items, and the insurer gives a typical reason for each:

Two of these points need a closer explanation. For diminished value, no calculation method is prescribed. Several methods are accepted and give different amounts for the same vehicle. An insurer review report that names a lower value but does not state its own method is only a counter-calculation. What causes diminished value is explained on our page on diminished value after a vehicle accident.

For residual value, the question is which market the counteroffer comes from. The Federal Court of Justice (BGH) has ruled that the general regional market is decisive and that the person whose car was damaged does not have to use special offers from outside the region (BGH, judgment of July 12, 2005, case no. VI ZR 132/04). Other decisions cover three topics. The first is the hourly rates of brand-authorized repair shops (BGH, judgment of April 29, 2003, case no. VI ZR 398/02). The second is markups on parts list prices in a fictitious settlement (fiktive Abrechnung). This means payment based on the calculation, without an actual repair (BGH, judgment of September 25, 2018, case no. VI ZR 65/18). The third is blend painting (BGH, judgment of September 17, 2019, case no. VI ZR 396/18). We name these decisions for context. A traffic law lawyer, not the expert, decides whether and how they apply to your case.

What should you do if your report was reduced?

1. Important: Do not sign or accept anything before an expert has reviewed the insurer review report.
2. Get the complete insurer review report, not only the cover letter with the reduced total. You need the item list, otherwise nothing can be checked.
3. Give the insurer review report to the expert who wrote the report. He knows the calculation and the vehicle.
4. Wait for the expert statement. It goes through the report item by item and says which removal is not technically correct and which is justified.
5. Give the expert statement to your law firm. From there, the lawyer takes over.

We offer exactly this path, see report review and expert statement for reductions. Step four is important: A good expert statement also admits what was correctly reduced. Anything else would not be credible and helps nobody in court.

How do you challenge another party's report technically?

This is not about opinion but about points that can be checked. These six points quickly show whether another report holds up:

• Prior damage research: Does the report record whether prior damage existed and how it was separated? Repaired prior damage (Vorschaden) and unrepaired old damage (Altschaden) are two different things, and the report must treat them separately.
• Calculation basis: Does the report state which calculation system and which repair shop group were used?
• Manufacturer specifications: Does the report distinguish between repair and required part replacement, especially for structural and safety parts?
• Photo documentation: Are there close-up photos of the damaged areas, or only overview photos from four directions?
• Residual value: Are specific regional offers named, or only a platform value?
• Diminished value: Is the method named, and can the parameters be followed?

If several of these points are missing, that is not yet proof of a wrong result. But it means the result cannot be checked. For a report, that is already a serious weakness.

When is a review worthwhile and when not?

More likely worthwhile: if several items were reduced, if the reduction is in the hundreds of euros or more, if the insurer refers you to another repair shop (Werkstattverweisung), or if, in a total loss (Totalschaden), residual value and replacement value (Wiederbeschaffungswert) are affected. Replacement value is the price of an equivalent replacement vehicle.
More likely not worthwhile: if one single small item was removed that really does not apply, or if the reduction is smaller than the effort of a review. We also tell you this before anything is ordered.

Who pursues the claims in the end?

This separation is important because the two are often mixed up. The expert says what is correctly calculated technically and in terms of costs. He does not write to the insurer, he does not negotiate, and he does not enforce anything. Your lawyer does that and uses the expert statement as the technical basis. Anyone who promises both from one provider goes beyond a limit that exists for good reason. If you are not sure whether a review pays off in your case, we clarify this beforehand.

Can a vehicle report be challenged at all?

A damage report (Schadengutachten) is not a judgment and not an official decision. So there is nothing you can formally object to. What exists is a technical dispute: a second, traceable calculation that is set against the first. The side with the better documentation and the clearer calculation is in the better position in the end. It does not matter who calculated first.

Two last distinctions, because they are often mixed up. A report ordered by a court in an ongoing civil case follows its own procedural rules. This is a different process from out-of-court claim settlement (Regulierung). And a report from a private accident insurance covers personal injury and the degree of disability. A doctor is responsible for that, not a vehicle expert.
