Quick Answer
A tested used original alternator is the right fix when the battery warning light, low system voltage or a battery that keeps going flat has been traced to the charging side, and the battery and drive belt have already checked out. It suits Malaysian owners who want an original Audi part at a lower price, tested before dispatch and covered by the warranty stated in the quote. For a daily-driven A4 or A5 in heavy KL traffic, with its constant stop-start electrical load, it restores charging with the part the car was built with.
Diagnosis and Common Symptoms
The alternator on the Audi A4 B8 and A5 8T with the CDH engine is regulated by the car's electronics, so a failing unit shows up as electrical symptoms before it stops charging altogether. Common signs:
- Battery or charging warning light on the dash, sometimes with a "battery charge" message in the instrument cluster.
- Headlights that dim at idle, or interior and infotainment glitches that clear when revs rise.
- A battery that goes flat repeatedly, even when the battery itself tests healthy.
- Whining or grinding from the front of the engine, usually a worn alternator bearing.
- Start-stop that stops working, or windows and seat functions that slow down, because the car cuts consumers when voltage is low.
- Stored fault codes such as P0562 (system voltage low), P0620 to P0622 (generator control or field circuit) or P0563 (system voltage high).
Before replacing the alternator, confirm battery condition, terminal and earth connections and drive belt condition. A voltage reading at the battery with the engine running separates a charging fault from a battery fault. A healthy system normally reads roughly 13.8 to 14.4 V at the terminals.
Introduction
This is a Genuine Used alternator for the Audi A4 B8 and A5 8T with the CDH engine, taken from an original Audi vehicle. Every unit is tested for working output before listing, so you receive a verified part and not an assumption. Because it is the original part the car was built with, regulator behaviour and mounting match the factory specification. It is a practical choice when you want original quality without the cost of a brand-new unit.

Frequently Asked Questions
What are the signs that the alternator on an Audi A4 B8 CDH is failing?
On an Audi A4 B8 with the CDH engine, a failing alternator typically shows a battery warning light, dimming headlights at idle, a repeatedly flat battery and a whining noise from the belt area. Fault codes such as P0562 (system voltage low) or P0620 to P0622 (generator control) may also be stored.
Does the Audi A5 8T alternator need coding or wheel alignment after replacement?
No wheel alignment applies to the Audi A5 8T alternator, because it is not a suspension or steering part. We do not list coding as a requirement for this alternator. If charging faults remain after fitting, check the battery and wiring, and clear any stored voltage fault codes.
Which Audi models does this CDH alternator fit, and how do I confirm the match?
This alternator is listed for the Audi A4 B8 and Audi A5 8T. To confirm the match, compare the number on your old alternator's label with the part number shown in the Part Numbers and Fitment section of this page. If you are unsure, send us your chassis number and we will check it before you order.
Who is a tested used original Audi A4 B8 alternator suited to?
A tested used original alternator suits A4 B8 and A5 8T owners who want an original Audi part at a lower price, with working output verified and the warranty stated in the quote. We also supply brand-new original (sealed, the longest life) and brand-new China-made (the lowest price, with an exchange warranty, not original), so you can choose by budget and how long you plan to keep the car.
Should I replace the alternator or the battery on my Audi A5 8T?
On an Audi A5 8T, test the battery and check the drive belt first. If the battery is healthy and running voltage at the terminals stays low, or the charging warning light stays on, the alternator is the likely cause. A battery that fails again soon after being replaced also points to the charging side.
