Bosch Original Equipment Alternators benefit from more than 100 years of alternator manufacturing experience, ensuring years of reliable charging performance, even under the most extreme operating conditions imaginable, from the sub zero temps of the northern plains to the blazing southwest desert heat. All Bosch Original Equipment Alternators are engineered, manufactured, and 100% tested to the highest industry standards Bosch is famous for, using all new, not remanufactured, components for maximum reliability and performance. Bosch Original Equipment Alternators incorporate only original equipment quality components to withstand the rigors of high heat environments and high electrical demand. Bosch Original Equipment Alternators are identical in fit and function to the OE parts they replace, yet benefit from the latest enhancements in engineering and charging technology for superior performance. All Bosch Original Equipment Alternators are ready for installation right out of the box. NOTE: Always ensure battery is fully charged before installing a new alternator. Alternators are engineered to keep batteries topped off, not to fully charge a dead battery. Using a new alternator to charge a dead battery can damage internal components, shortening the life of the alternator.

Why Alternator Health Matters on VW & Audi Platforms
Once the engine is running, the alternator is the primary electrical power source for:
-
Engine and transmission control modules
-
Electric power steering
-
Turbo management and cooling systems
-
Infotainment and digital clusters
-
Driver-assist and safety systems
-
Charging and maintaining the battery
When alternator voltage drops even slightly, VW/Audi systems don’t “sort of work” — they trigger faults. Replacing the alternator restores proper system stability, not just battery charge.
Why Bosch OE Matters (Especially Here)
Volkswagen Group charging systems demand:
-
Tight voltage regulation
-
Clean electrical output
-
Correct amperage under load
The Bosch AL0170N delivers:
-
Stable voltage at idle and highway speeds
-
Proper battery recharge after cold starts
-
Smooth output without voltage spikes
-
Reduced stress on sensitive control modules
This is how you prevent electrical problems instead of chasing them.
At Bosch, We’re 100% Focused on Quality to Ensure Performance, Durability, and Long Term Endurance
Functional & Performance Testing
Each Bosch Alternator and Starter is tested to ensure functionality and performance aligns with manufacturer specifications. This testing means the part will produce the same performance as the OE part.
Brand-New OE Construction
The Bosch AL0170N alternator features:
-
New high-efficiency copper windings
-
OE-spec internal voltage regulation
-
Precision-balanced rotor and premium bearings
-
Factory-correct mounting and electrical connections
No reman internals. No core charges. No surprises.
Endurance Testing
To ensure Bosch replacement parts deliver optimal performance for the lifetime of the part, test benches simulate the lifetime of the component to prove durability and endurance requirements are met.
Water Intrusion Testing
Bosch water intrusion testing ensures that part function does not vary due to any water impact during inclement weather. Splash water tightness testing to IPX4, IPX4K, and IPX9K standards.
Climate Stability Testing
All new Alternator and Starter product releases are subjected to cold storage (-40F), heat storage (+248F), and changes in humidity to ensure parts work in all temperatures and can withstand thermo-shock.
