M157 Pressure Transducer, Vacuum Pump and Vacuum Lines

This information applies to your vehicle - VIN: ee

March, 2026

Dear Mercedes-Benz Owner:

In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of
our customers, Mercedes-Benz USA is extending the warranty coverage on the pressure transducer, vacuum pump, and
vacuum lines in your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years/
150,000 miles (whichever occurs first). This applies to the vehicle regardless of ownership.

Why the Warranty extension?

On certain Model Year 2015 - 2019 CLS, E-Class, G-Class, GLE, GL, GLS, ML, SL and S-Class vehicles with
/\ the “M157” 8-cylinder engine, over time, the pressure transducer and vacuum pump might not continue to

work as intended and could result in illumination of the check engine Malfunction Indicator Lamp (‘MIL’)

and the activation of limp-home mode.

Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz
dealership.

e If your preferred authorized Mercedes-Benz dealership performs diagnosis and confirms that your
vehicle meets the criteria for this extended warranty, the repair will be covered at no cost to you.

e This extended warranty does not apply to any other components or conditions beyond the ones
described under this extended warranty, and standard warranty terms apply, including the exclusions
with respect to extra expenses, as identified in the Service and Warranty Information booklet.

We hope you are enjoying your Mercedes-Benz vehicle, and we apologize for any inconvenience this may have caused.

Sincerely,
Mercedes-Benz USA
