Purpose and compatibility

The presented Bosch alternator has been designed for Mercedes ML W164 and GL X164 class vehicles with the OM629 diesel engine. The design, matched to the drivetrain of these models, allows for the maintenance of factory charging parameters, which is particularly important for extensive onboard electronics, comfort systems, and advanced safety systems.

Thanks to the use of proven Bosch technology, the alternator provides a stable 14V voltage and high current efficiency, which translates into reliable operation of all electrical consumers – from engine control units and assistance systems to multimedia equipment.

Operating parameters and technical characteristics

The alternator offers an output of 220A, which allows for the safe powering of vehicles with a large number of electrical consumers and additional modules. Such values are particularly beneficial in cars equipped with:

• extensive audio and multimedia systems,
• heated seats and windshields,
• advanced driver assistance systems,
• additional accessories requiring a stable power supply.

A constant operating voltage of 14V promotes proper battery charging and limits the risk of voltage drops that could affect the operation of controllers and sensors. As a result, the alternator supports trouble-free operation of the electrical system in daily use and during long journeys.

Condition, origin, and advantages of use

The offered alternator is a used part, sourced from the dismantling of a Mercedes vehicle. This type of part is an attractive solution for users who want to maintain the factory specification of the car while optimizing repair costs. Using an original Bosch alternator allows for maintaining compatibility with the electrical installation and the parameters specified by the vehicle manufacturer.

Choosing an original alternator from this group means, among other things:

• preservation of factory mounting points and electrical connections,
• proper fit for the OM629 diesel engine,
• charging parameters consistent with the requirements of Mercedes electronics.

Application in diesel vehicles

Diesel engines, especially in larger SUVs such as the ML W164 and GL X164, require a stable power supply due to the high loads on the starter, glow plug systems, and numerous control units. The 220A Bosch alternator has been adapted to work in such conditions, ensuring an adequate current reserve even during intensive vehicle use.

Thanks to this solution, the charging system remains efficient both in city traffic and during long journeys with additional consumers switched on, which reduces the risk of battery discharge and starting problems.
