Nearly 850,000 Mercedes diesels at risk of fire due to faulty valve



Mercedes-Benz is recalling 848,517 vehicles from the C-Class, E-Class, G-Class and S-Class, as well as the CLS, GLC, GLE and GLS model series worldwide. Affected vehicles were manufactured between January 2017 and October 2021 and are equipped with a diesel engine.

The reason for the measure is an electrical switching valve. According to press reports, coolant can enter the vacuum circuit and come into contact with the affected valve. As a result, there is a risk of fire due to electrochemical reactions and rising component temperatures.



The German Federal Motor Transport Authority (KBA) also confirms a fire hazard, although its recall database only mentions exhaust gas recirculation and not coolant in the vacuum circuit.

A software update is carried out in the workshop, and the faulty valve is also replaced. The internal code for this recall is “2090008“.

What the owner should do?

If you read about a recall that you think may affect your car, you should make immediate contact with a dealer or workshop that’s been officially authorised to perform repairs on behalf of the manufacturer and ask for the details.

If you wish to know more about eventual problems of a specific car (e.g. real mileage, potential traffic accidents damages, odometer rollback, repairs, etc.), then we suggest going to HPI-Check.
