Owning a 2005 Audi A4 1.8T with the AMB engine is a rewarding experience. Its turbocharged performance and sleek design make it a favorite among car enthusiasts. But like any vehicle, it needs regular maintenance to keep running smoothly. Two critical components that often require attention are the CV joints and tensioners. If you’re looking for reliable replacement parts, Febi Bilstein is a trusted name in the automotive world. In this guide, we’ll explore everything you need to know about Febi Bilstein CV joints and tensioners for your Audi A4 1.8T AMB, why they matter, how to maintain them, and tips for choosing the right parts.
What Are CV Joints and Tensioners?
Before diving into Febi Bilstein’s offerings, let’s break down what these parts do in simple terms.
CV Joints: The Power Transfer Heroes
CV (Constant Velocity) joints are essential for your Audi’s drivetrain. They connect the transmission to the wheels, allowing power to transfer smoothly while the wheels turn and the suspension moves. In your 2005 Audi A4 1.8T, which likely has a front-wheel-drive or Quattro all-wheel-drive system, CV joints are found in the axles. They ensure your car accelerates and handles corners without hiccups.
Over time, CV joints can wear out, especially if the protective rubber boot tears, letting dirt and moisture in. A failing CV joint might cause clicking noises when turning, vibrations, or even loss of power to the wheels. Replacing them with high-quality parts is crucial to keep your Audi performing at its best.
Tensioners: Keeping the Engine in Sync
Tensioners are part of your engine’s timing or accessory belt system. In the 2005 Audi A4 1.8T AMB, the timing belt tensioner ensures the timing belt stays tight, keeping the engine’s camshaft and crankshaft in perfect sync. This is vital for the 1.8T’s turbocharged engine, as any misalignment can lead to poor performance or severe engine damage.
There’s also the accessory belt tensioner, which maintains tension on the serpentine belt that powers components like the alternator, power steering pump, and air conditioning compressor. A worn tensioner can cause belt slippage, squealing noises, or accessory failures, leaving you stranded or without essential functions like charging or cooling.

Replacing a timing belt tensioner is a complex job best left to professionals unless you’re experienced. The serpentine belt tensioner is easier for DIYers. Here’s a basic guide for the latter:
-
Locate the Tensioner: Find the serpentine belt tensioner under the hood, near the alternator or power steering pump.

Remove the Old Tensioner: Unbolt the tensioner (usually one or two bolts) and remove it.
-
Install the Febi Bilstein Tensioner: Bolt on the new tensioner, ensuring proper alignment.
-
Reinstall the Belt: Route the serpentine belt according to the diagram (check your owner’s manual) and release the tensioner.
-
Test: Start the engine and check for proper operation.
Note: For timing belt tensioners, replace the entire timing belt kit (belt, tensioner, water pump) every 75,000–100,000 miles to prevent catastrophic engine failure.
Maintenance Tips
-
Follow Service Intervals: Replace the timing belt and tensioner every 75,000–100,000 miles or as per Audi’s recommendations.
-
Check Belt Condition: Inspect the serpentine belt for cracks or glazing during oil changes.
