Audi A4 steering rack Without Speed Sensor Port
In seeking to purchase an alternative steering rack for your A4’s model may be described as being ‘without speed sensor port’. What does this actually mean?
What the Speed Sensor Port Does
When looking for a replacement steering rack for your Audi A4 it may be listed as a steering rack “without speed sensor port” or with a part number that matches the part number of your existing rack. It is also worth noting that some Audi A4 models have a threaded port on the steering rack where the speed sensor is attached. In most cases the speed sensor is attached to the speedometer in the dashboard. The power steering system can use the speed from the road to adjust the level of assistance the system gives at different speeds. This port and sensor are not used on all models of Audi A4.
Confirming Which Version Your Car Needs
Check the current steering rack fitted to your vehicle before you purchase a replacement. If your current steering rack does not have a sensor port and also lacks a wiring connector for a speed sensor near the steering rack then you will require a steering rack without speed sensor port. Also check your vehicle’s VIN number to confirm the original steering rack fitted to your vehicle and obtain a correct replacement from an Audi dealer or reputable parts supplier.
Why Fitting the Wrong Variant Causes Problems
In both cases serious problems can occur for your car. If you install a rack with a sensor port where the car expects none, the steering will be faulty and give error codes to the power steering. If you install a rack without a sensor port where the car expects one, you will get strange power steering assistance and possibly a warning light will appear. This warning light can even result in an MOT failure. We recommend you to check your vehicle’s MOT history for any previous steering advisories to get more information about the history of your car before replacing parts.
Checking Part Numbers Before You Buy
Make sure you cross reference the part numbers for the steering rack on your car with the part numbers for the replacement steering rack that you are purchasing (even if it is a remanufactured item). This is especially important for various versions (OEM spec) of the steering rack for the A4 model, as there are occasions when listings will have mixed inventory.
It’s worth taking the time to ensure the parts you need are correct to avoid having to send something back which will only add to the hassle and cause more problems when returned.
