When purchasing a replacement steering rack for an Audi, it is not as simple as searching for your model and year. We must also check the engine code as there are different types of steering racks fitted as standard to certain engines.
What the Engine Code Tells You
Audi identify different engines by a 2, 3 or 4 letter code (e.g. AEB, ALP, AUU, CAV, CAY etc.) stamped into the block near the cylinder head. This code is often shown on a sticker inside the service book or on the drivers side door jamb. The code will give information on the number of cylinders and size of the engine as well as any additional items such as the power steering being matched to the engine at the factory.
Where Engine Code Differences Affect the Rack
Audi models with different Engine Codes within a given model series are typically fitted with different type Steering Racks, designed by the factory to match the torque characteristics of the respective engine(s) and other components, such as ancillaries.
Gearbox Type Adds Another Variable
Manual and Automatic models have different Steering Rack ratios. In addition, models fitted with Automatic Gearboxes have a greater weight distribution than their manual counterparts. Therefore, the Gearbox Code must also be supplied in order to ensure correct Steering Rack compatibility.
Checking for a Speed-Sensitive System
This type of steering gear is fitted to Audi models that are equipped with speed-sensitive power steering (SSPS). In order to ensure correct fitment, please check your original steering rack for a solenoid port.
