Standard Ignition VCP171 vacuum pump for the 2010-2014 Mercedes-Benz ML350 and other vehicles maintains vacuum for the brake booster and auxiliary systems. This Standard Ignition vacuum pump was extensively tested to OE specifications for long service life.
A hard brake pedal, weak booster assist or a leak at the pump can mean the vacuum pump is worn, though a cracked vacuum line or a failing brake booster can be behind them too, so find the cause before replacing it.
The 2010-2014 Mercedes-Benz ML350, the 2013 Mercedes-Benz R350 and the 2012-2013 Mercedes-Benz E350 are among the vehicles this vacuum pump fits, and it is a direct-fit OE replacement for them. If your car is not named here, find it in the "Vehicles it fits" section.

Will this E350 vacuum pump fit a 2012-2013 Mercedes-Benz E350?
Yes. Standard Ignition VCP171 is a direct-fit replacement for the 2012-2013 Mercedes-Benz E350, and the 2010-2014 Mercedes-Benz ML350 takes it too.
Do I need to buy bolts or a gasket separately for this vacuum pump?
Yes. The box holds one vacuum pump only. Hardware and a gasket or seal are not included, so get new ones instead of reusing the old.
Is the Standard Ignition VCP171 belt-driven or electric?
It is belt-driven. The VCP171 is a mechanical vacuum pump with a metal housing and no relief valve.
What are the signs of a failing belt-driven vacuum pump?
A hard brake pedal, weak booster assist or a leak at the pump can mean it is worn. Have brake symptoms looked at promptly; a shop can test the pump's vacuum.
Is the VCP171 vacuum pump pressure tested?
Yes. Each VCP171 undergoes 100% pressure testing to prevent leaks, and its O-rings and seals are there to maintain proper vacuum pressure.
