Mercedes-Benz S-Class

The risk

In the event of an independent hardware failure, the lambda control in the Engine Control Unit (ECU) software can erroneously increase the amount of injected fuel during cylinder deactivation. As a result, exhaust temperatures can increase and this can damage surrounding components (e.g. engine wiring harness, catalytic converter). This can create an unexpected loss of propulsion, increasing the risk of accidents and injuries. Moreover, this can increase the risk of fire. In addition, local statutory exhaust emission limits could be exceeded. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

Product: Passenger car with an 8-cylinder petrol engine.
