Audi A5 Sportback 45 TDI Quattro drivetrain
The Audi A5 Sportback 45 TDI Quattro combines elegant styling with punchy performance and sophisticated engineering. To retain that unique driving dynamic and the dependable stability delivered by the Quattro system, every single component within the drivetrain must perform flawlessly. The drivetrain is tasked with transferring the hefty torque from the six-cylinder diesel engine to all four wheels, placing immense demands on the precision and durability of every individual component. When running an Audi A5 Sportback with this engine option, compromising on the quality of your replacement parts simply is not an option.
Here at CVJoint24, you will find parts engineered specifically for the 45 TDI Quattro model. Our focus is on supplying components that match original equipment specifications, ensuring your vehicle's dynamic handling characteristics remain intact. Whether you need a complete drive shaft or an individual CV joint, you can rely on our products being thoroughly tested to withstand the stresses of everyday commuting as well as spirited drives along winding country roads.
How the Audi A5 Sportback 45 TDI Quattro drivetrain is configured
The driveline layout of the Audi A5 Sportback 45 TDI Quattro is a true masterclass in German engineering. The engine is mounted longitudinally, typical of larger Audi platforms, sending its power through an advanced gearbox to the permanent Quattro all-wheel drive system. This setup actively divides torque between the front and rear axles depending on traction and driving conditions. To transfer this output smoothly to the wheels, several driveshafts and constant velocity joints are used, engineered to cope with high articulation angles and constant deflection while travelling.
The front drive shafts take on a particularly demanding workload, as they must transfer driving torque whilst steering the vehicle. The outer CV joints enable the road wheels to turn as they rotate, while the inner joints absorb the plunging axial movements caused by suspension travel. With the substantial torque generated by the 45 TDI engine, the load on these joints is considerable, particularly under hard acceleration from a standstill. Appreciating this complexity is key to selecting durable replacement parts that truly stand the test of time.
Common faults and symptoms
There are several telltale symptoms indicating that driveline components on your Audi A5 Sportback 45 TDI Quattro are beginning to wear out. One of the most typical signs of a worn outer CV joint is a rhythmic clicking or knocking noise when cornering sharply at low speeds, such as during parking manoeuvres. This noise is frequently caused by lubricating grease escaping past a split boot, allowing grit to penetrate and cause accelerated wear to the steel balls and bearing tracks.
If, on the other hand, you feel vibrations through the steering wheel or throughout the cabin under acceleration, this often points towards a worn inner CV joint. These tremors can be faint initially, but they progressively worsen the harder the engine pulls. Another warning sign to check for is grease splattered around the inside of the wheel rim or wheel arch, signalling a split CV boot. Remedying these problems early is vital to prevent secondary damage to the gearbox or wheel bearings, which can prove far more costly to fix.
Commonly replaced parts for Audi A5 Sportback 45 TDI Quattro
When the time arrives to service or repair your drivetrain, certain components require replacement more often than others. For the Audi A5 Sportback 45 TDI Quattro, our inventory centres on three primary part categories to keep you covered. By swapping worn components for precision-engineered new replacements, you can restore your car's factory-level refinement and safety.
- Drive shaft Audi A5 Sportback 45 TDI Quattro – A comprehensive solution when inner and outer joints are worn out or the shaft itself suffers from unbalance.
- Outer CV joint Audi A5 Sportback 45 TDI Quattro – The most common replacement to eliminate clicking sounds when cornering.
- Inner CV joint Audi A5 Sportback 45 TDI Quattro – Crucial for curing acceleration vibrations and ensuring smooth torque delivery from the gearbox.
Alongside these complete units, fitting new CV boots and retaining clamps is routine maintenance. An intact boot provides the ultimate protection against premature joint wear. We always advise checking boot condition during routine servicing so you can take action long before the constant velocity joint itself incurs damage.

Frequently Asked Questions about Drivetrain parts for Audi A5 Sportback 45 TDI Quattro
How do I know if my Audi A5 Sportback 45 TDI Quattro needs a new drive shaft?
The most common signs are pronounced vibrations under acceleration or persistent noises that do not disappear after replacing only a single CV joint. If the shaft has become bent or both joints are severely worn, a complete drive shaft is the best solution.
What is the difference between an inner and outer CV joint on this model?
The outer CV joint sits closest to the wheel and handles steering angles; it typically produces clicking noises when cornering. The inner CV joint sits closest to the gearbox and accommodates suspension movement; wear here usually causes longitudinal vibrations under load.
Can I replace just the CV boot instead of the entire joint?
Yes, if you catch a split CV boot in time before dirt and moisture penetrate and damage the joint bearing surfaces, you can replace just the boot. However, if unusual noises can already be heard, the joint is usually beyond saving and should be replaced.
Why is the Quattro system sensitive to worn drivetrain components?
The Quattro system actively distributes power between the wheels. If a CV joint or drive shaft has play or imbalance, it can disrupt the system's ability to distribute torque efficiently, leading to reduced traction and accelerated wear on the differentials.
How does your fitment guarantee work for Audi parts?
When you select your make, model and engine variant in our search filter, we guarantee that the parts displayed will fit your specific Audi A5 Sportback 45 TDI Quattro. In the unlikely event that an item does not fit, we will help you exchange it for the correct part without any fuss.
