Inner CV joints for Audi A3 Saloon 40 Tfsi
Maintaining the drivetrain on a modern car like the Audi A3 Saloon 40 Tfsi is crucial to preserving the car's performance and ride comfort. The inner CV joint plays a central role in this system. As a Swedish driveline specialist, we understand the specific demands placed on Audi components. An Audi A3 Saloon 40 Tfsi demands parts engineered to handle both the torque from the engine and the movements occurring within the suspension while driving. We supply only parts that meet or exceed original specifications to guarantee a long service life.
When you choose an inner CV joint from us, you can rest assured that you are receiving a product carefully selected for its quality. We know our customers value both dependable reliability and straightforward installation. That is why our products are designed to fit your vehicle's existing system with exact precision, minimising the risk of future problems. By focusing on specialist drivetrain knowledge, we offer deeper technical expertise than general car parts shops, which is particularly vital for technically advanced models like the A3 Saloon.
What does an inner CV joint do on the Audi A3 Saloon 40 Tfsi?
The inner CV joint is mounted closest to the gearbox on the drive shaft. Its primary role is to transmit drive from the gearbox to the drive shaft, whilst allowing the shaft to plunge inwards and outwards. This axial movement is essential because the distance between the gearbox and the wheel hub changes constantly as the suspension travels up and down on the road. For an Audi A3 Saloon, this function is critical to maintain smooth power delivery regardless of road conditions or load.
Unlike the outer CV joint, which primarily accommodates steering angles, the inner constant velocity joint focuses on absorbing length variations and vertical travel. If this component fails to work correctly, the vehicle's entire driving dynamics suffer. On an Audi A3 Saloon 40 Tfsi, where precision and driving enjoyment are paramount, it is especially important that the inner CV joint remains in sound condition to avoid unnecessary wear on the gearbox output shafts and bearings. A properly functioning joint ensures power reaches the tarmac without losses or disruptive vibrations.
Common symptoms of wear
Wear on an inner CV joint often presents differently from that of an outer joint. The most frequent symptom is vibration through the car body under acceleration. These vibrations are typically felt as a shudder through the whole car, rather than just in the steering wheel. If you notice your Audi A3 Saloon 40 Tfsi vibrating when pressing the accelerator, with the shaking subsiding as soon as you lift off, it is a classic sign that the inner joint is worn or running dry of grease.
Another symptom is knocking noises when driving over bumps or during harsh vertical suspension movements. It is also essential to inspect the CV boot protecting the joint on a regular basis. If the boot splits, lubricating grease escapes and dirt enters, rapidly destroying the internal bearing surfaces. Catching a split boot early can save significant expense, as it is often possible to save the joint simply by fitting a replacement boot and packing it with fresh grease before permanent damage occurs.
How to choose the right inner CV joint
Finding the correct Inner CV joints can be challenging, as several variations often exist depending on the gearbox type, engine code and production year. For the Audi A3 Saloon 40 Tfsi, it is vital to verify the spline count on both the gearbox side and the drive shaft connection. The joint's overall diameter and mounting design can also differ. Guessing the right part often results in unnecessary returns and avoidable vehicle downtime.
The most reliable method to ensure a correct fit is to use our vehicle selector by choosing your car's make, model and engine variant. Filtering by your exact vehicle configuration brings up the components tailored to your car. If you are ever in doubt, we also recommend checking the technical specifications we provide against the part fitted to your vehicle. Our Inner CV joints for Audi A3 Saloon category is structured to make finding the right replacement part as simple and dependable as possible.
Related parts to check
We also recommend inspecting these exact pages for the same car when working on the inner CV joint:
When one drivetrain component exhibits wear, adjacent parts on the same vehicle frequently warrant an inspection as well. Comparing these exact pages for the Audi A3 Saloon 40 Tfsi makes it easier to establish whether the problem lies strictly within the inner CV joint or in a neighbouring section of the transmission.
This is particularly relevant on models where vibrations, play and unwanted noises can transfer symptoms across several parts within the same drivetrain. A quick check of related categories reduces the risk of replacing the correct type of component while overlooking an adjacent worn part that produces identical symptoms.
Carrying out a thorough inspection of the drivetrain ensures your car remains dependable over many kilometres to come. We supply a comprehensive selection of these spare parts so you can find everything you need in one place.

Frequently asked questions about inner CV joints for Audi A3 Saloon 40 Tfsi
How do I know if the inner CV joint is failing on my Audi A3 Saloon 40 Tfsi?
The most common symptoms are vibrations through the body shell under acceleration and load. These vibrations typically stop when you lift off the throttle, unlike wheel imbalance which is felt constantly.
Can I replace just the inner CV joint, or must the complete drive shaft be replaced?
On the Audi A3 Saloon 40 Tfsi, you can usually replace just the inner CV joint on its own, provided the drive shaft bar itself is neither damaged nor bent.
Are the CV boot and grease included when I buy an inner CV joint from you?
Yes, our inner CV joints are supplied as complete kits including the joint, model-specific CV boot, high-quality grease and the necessary hardware such as clips and bolts.
Why is the correct number of splines on the CV joint so important?
Splines are the teeth that transmit drive. If the tooth count does not match precisely, the joint will not fit onto the drive shaft or into the gearbox, making installation impossible.
How does your fitment guarantee work for the Audi A3 Saloon?
When you select your car's exact make, model and engine variant, we guarantee that the part fits your specific car. In the unlikely event that it is incorrect, we will promptly help you find the right part.
What is the difference between an inner and an outer CV joint?
The inner CV joint sits by the gearbox and accommodates the in-and-out plunge movements of the shaft. The outer CV joint sits at the wheel hub and allows the wheels to turn for steering whilst transmitting drive.
