Audi A4 1.4 Tfsi drivetrain
The Audi A4 1.4 Tfsi is a model that combines efficiency with Audi's renowned engineering. The drivetrain in this specific model is engineered to handle the torque from the turbocharged engine smoothly and effectively. As the owner of an Audi A4 1.4 Tfsi, it is important to understand that drivetrain components are subjected to constant mechanical stress while driving. At CVJoint24, we specialise in these very parts to ensure you get access to spare parts that match original equipment quality. By focusing on specific components such as drive shafts and inner CV joints, we provide deeper technical expertise than general car parts retailers. Our goal is to be your primary partner for your Audi's power transmission, combining technical know-how with a range tailored to your car's unique specifications. Keeping the drivetrain in prime condition is not only a matter of operational reliability, but also directly influences fuel economy and the overall driving experience in your Audi.
How the drivetrain is engineered on the Audi A4 1.4 Tfsi
The drivetrain on an Audi A4 1.4 Tfsi is a sophisticated assembly that transfers power from the engine to the front wheels with high precision. The system consists of several interacting components, where the gearbox sends power through the drive shafts out to the wheel hubs. A central part of this system is the inner CV joint, mounted against the gearbox, allowing the drive shaft to plunge and move up and down in line with the suspension. The outer CV joint, situated at the wheel hub, enables steering articulation while simultaneously transferring drive. For the Audi A4 1.4 Tfsi, the precision of these components is vital to eliminate vibrations and energy loss. Material selection for the shafts and the quality of the grease inside the joints are optimised to withstand the thermal and mechanical stresses encountered during both city driving and sustained motorway speeds. This balance between strength and flexibility gives Audi its characteristic ride comfort. Understanding this design helps you appreciate the importance of choosing the correct specification when replacing components, as even minor discrepancies can upset the balance of the entire driveline.
Common faults and symptoms
There are several distinct signs that the drivetrain on your Audi A4 1.4 Tfsi is wearing out. One of the most frequent symptoms is vibration felt through the car body or steering wheel during acceleration. This often indicates that an inner CV joint on your Audi A4 1.4 Tfsi has developed excessive play or lost its lubrication due to a split boot. Another classic sign is a clicking or knocking noise when turning on full lock at low speeds, which usually points to a worn outer constant velocity joint. If you notice grease splattered inside the wheel rim or around the gearbox flange, a CV boot has torn. If left unaddressed, dirt and road grit will enter the joint, causing complete failure. Ignoring these symptoms can lead to secondary damage to the gearbox and wheel bearings, making the repair significantly more expensive in the long run. By paying attention to these early warning signs, you can save both time and money by replacing worn components before they leave you stranded.
Common parts to replace on the Audi A4 1.4 Tfsi
For the Audi A4 1.4 Tfsi, two main categories of components are most frequently required for driveline repairs. Firstly, a complete drive shaft for the Audi A4 1.4 Tfsi. Replacing the complete driveshaft is often the most cost-effective solution, providing both inner and outer joints alongside brand new CV boots in a single unit, which saves considerable workshop labour. Secondly, the inner CV joint is a common wear part, particularly on vehicles driven frequently in stop-start urban traffic. Proactive replacement of CV boot kits is also recommended to safeguard the more expensive metal parts. In our catalogue, you will find components rigorously tested to meet the high standards demanded by a modern Audi. We supply:
- Complete drive shafts for both right and left sides, balanced to perfection.
- Inner CV joints complete with required fittings and high-performance grease.
- CV boots in high-grade rubber or durable thermoplastic designed to resist temperature extremes.
- Fitting kits containing model-specific circlips and bolts for Audi applications.
By choosing the correct parts from the start, you ensure that your Audi retains its original handling refinement and safety over many thousands of kilometres.

Frequently Asked Questions about the Drivetrain for Audi A4 1.4 Tfsi
How do I know if my Audi A4 1.4 Tfsi needs a new drive shaft?
The most common signs are vibrations under acceleration, clicking noises when turning, or visible grease leaking from the CV boots. If vibrations increase with speed, it often indicates unbalance or wear in the drive shaft.
