Peugeot Partner Alternator

A replacement alternator for popular Peugeot models like the 208, 2008, or 308 typically costs between R2,500-R6,500 for the part, with labour adding another R800-R1,500 depending on the workshop. Original Peugeot alternators are more expensive but come with warranty, while quality aftermarket units from brands like Bosch or Valeo offer good value. Models with BlueHDi engines may require higher-output alternators that cost toward the upper end of this range.

Under normal South African driving conditions, a Peugeot alternator should last between 100,000-150,000 km or 5-7 years. However, frequent short trips, extreme heat in provinces like Limpopo and Mpumalanga, and dusty conditions can reduce this lifespan. Regular servicing and ensuring the serpentine belt is properly tensioned can help maximize alternator life in EP6, THP, and DV6 engine applications.

You should not drive with a completely failed alternator, as your vehicle will run solely on battery power which typically lasts only 30-60 minutes before the engine dies. If the alternator is partially failing, you may make it to a workshop, but turn off all non-essential electrical items like air conditioning and radio. Continuing to drive risks stranding yourself and potentially damaging the battery and other electrical components in your Peugeot.

Common causes include worn bearings from high mileage, damaged voltage regulators from electrical spikes, a slipping or broken serpentine belt, water ingress from driving through deep puddles, and excessive heat exposure. In South African conditions, dust and debris entering the alternator housing is particularly problematic. On turbocharged THP and BlueHDi engines, the increased electrical demands from multiple sensors and systems can also accelerate wear on older alternators.

Start the engine and use a multimeter to measure battery voltage—it should read between 13.8-14.4 volts with the engine running if the alternator is charging correctly. Turn on headlights, air conditioning, and other accessories; voltage should remain stable above 13.5 volts. Any AA or workshop in South Africa can perform this test quickly, and most Peugeot dealerships include alternator testing as part of routine services on models like the 3008 and 5008.
