At low temperatures and high speeds, the steering wheel of the Audi Q5 vibrates or pulls. This persistent problem especially affects models from 2016–2021. The cause is often the steering rack, the universal joint or electrical faults in the power steering (problems in the electronic control of the steering) that require a software update or replacement. These well-known steering issues are annoying and affect road safety. Do you want to know how to recognise this in time and what you can do about it?
Common symptoms in cold temperatures
When you drive your Audi Q5 in cold weather, you may suddenly notice resistance in the steering. The steering feels normal in the centre position, but when you turn, you suddenly feel binding. Sometimes the steering briefly frees up, only to become stiff again. This pattern occurs mainly at specific steering angles.
Owners also regularly report vibrations while driving on the motorway. At higher speeds the steering feels nervous or may even start to shake. These complaints are typical of Audi Q5 car problems in models from the production years 2016 through 2021. The problem often gets worse when the temperature drops below zero.
In addition, some drivers hear clicking or squeaking noises when turning the steering wheel. These sounds point to internal wear or leaks in the steering system. The steering wheel controls on the wheel itself can also suddenly stop working due to connectivity issues with the control module (the electronics that control the power steering).
‘ These faults often occur after a few years of use, especially in cars that are frequently driven in wet conditions. ’
Causes of steering problems
The universal joint in the steering column often seizes up due to exposure to moisture and road salt. This U-joint ensures smooth movement in multiple axes, but corrosion causes binding. In cold conditions this gets worse, because metal components move less freely.
The steering rack itself can also cause problems. Internal leaks of power steering fluid lead to reduced assistance and a stiff steering feel. In models from 2016–2021 the steering rack has proven to be prone to wear, which causes play and oil leaks.
Electrical faults also play a role. The steering sensor or the control module can fail, resulting in error messages and loss of electric power steering. These faults often occur after several years of use, especially in cars that are frequently driven in wet conditions.
Furthermore, the power steering pump and associated belt can wear. A worn belt causes whining or squeaking noises, while a faulty pump leads to increased steering effort. Low fluid levels due to leaking connections make this problem worse.
How to test the steering when buying a used car
Start with a visual inspection underneath the car. Park the Audi Q5 on a level surface and look for leaks under the engine and around the steering rack. Power steering fluid is recognisable by its reddish-brown colour and oily texture.
Then check the fluid level in the power steering reservoir. Open the bonnet and look for the reservoir with the steering wheel symbol. The level must be between the minimum and maximum markings. If it is low, this indicates a leak or wear.
Test the steering during a test drive at different temperatures and speeds. Pay attention to:
- Resistance or binding when turning from a standstill
- Unusual noises such as clicking, squeaking or whining
- Vibrations or nervous behaviour at motorway speeds
- Play in the steering, especially around the centre position
- Failure of steering wheel controls or warning messages on the dashboard
Ask the seller or dealer about known problems with the steering system. If in doubt, have an OBD scan carried out to check fault codes (error messages in the car’s computer). Codes related to the steering sensor or the power steering system are alarming and require further investigation.
Also check whether a software update has already been carried out for the power steering. Many dealers are aware of the problem and have updates available that improve steering response.
Software update for power steering fault
Audi has released software updates for certain Q5 models that recalibrate the electric power steering. This update adjusts the steering response and can reduce vibrations and binding. The update is carried out at an Audi dealer and takes about an hour.
However, the software solution does not always work. In models with physical damage to the steering rack or worn components, replacement remains necessary. Always have a full diagnosis performed first before opting for an update.
Some owners report that the steering sensor needs to be recalibrated after the update. This is done with specialised equipment and must be carried out by a professional workshop. Incorrect calibration actually leads to more problems with the power steering.
The cost of a software update is between 100 and 200 euros, depending on the dealer. Replacing the steering rack is considerably more expensive and quickly costs 1,500 to 2,500 euros including labour. Therefore consider the cheaper software solution first before proceeding to costly repairs.

Practical repair tips and solutions
With minor steering problems you can carry out a few checks yourself. Start by changing the power steering fluid. Top up the reservoir with fresh fluid, start the engine and turn the steering wheel from full left to full right until the fluid remains clean and free of foam.
Is the U-joint the culprit? Replacement is possible without specialist tools. Disconnect the pinch bolt under the footwell and raise the car to gain access to the second bolt at the joint. Remove rust, lubricate the joint with suitable grease and reassemble everything. Then test whether the steering turns smoothly in all directions.
You can replace cracked or leaking hoses by loosening the clamps and fitting a new hose. Make sure you use a compatible hose that can withstand high pressure and temperatures. You can also replace the belt of the power steering pump yourself by releasing the tensioner and routing the new belt in the correct pattern.
For electrical faults in the power steering, professional help is essential. Have a garage read out the fault codes (error messages in the car’s computer) and check the steering sensor. Recalibration or replacement of the control module (the electronics that control the power steering) often solves this. If there is play in the steering rack, consider having it reconditioned instead of completely replaced. This is cheaper and often delivers the same result.
Prevention and maintenance
Check the steering system every year for rust, leaks and wear. The U-joint in particular deserves attention, as it is vulnerable to moisture and road salt. A quick check can prevent later problems.
Always use the correct power steering fluid specified by Audi. The wrong fluid can damage the pump and internal seals. Check the fluid level regularly and top up if necessary.
For cars that are often driven in wet or cold conditions, it is advisable to hose down the underside thoroughly after winter. This removes salt and dirt that cause corrosion.
During the annual service, have the steering system included in the inspection. A professional workshop can detect play, leaks and wear in good time before they lead to bigger problems.
When to go to the garage
Go to a garage immediately if the steering becomes heavy, cuts out or if warning messages suddenly appear. These signals point to problems that directly affect handling and safety.
Persistent vibrations or binding that do not disappear after changing the fluid also require professional diagnosis. Reduced power steering assistance can lead to dangerous situations, especially during emergency manoeuvres.
Leaks under the car also demand swift action. A low fluid level damages the pump and can lead to complete failure of the steering system.

Frequently asked questions
The most common symptoms are heavy or jerky steering, especially at certain steering angles, and squeaking, humming or clicking noises when steering. You will often also see leaking or dropping power steering fluid and possibly oil traces around the steering rack or hoses. In addition, electrical faults can occur, such as warning messages or temporary loss of power steering due to sensor or module problems. Noticeable play in the steering or vibrations in the steering wheel also indicate wear in the steering system.
On the Audi Q5, the U-joint (cross joint) in the steering column, the steering rack (including bushes and seals) and the power steering components such as hoses and lines are particularly prone to wear and failure. In addition, the power steering pump and drive belt wear relatively often, which can lead to heavy or noisy steering. Sensors and the electronic steering module can also develop faults due to wear or electronic defects. Regular inspection of these components helps prevent major damage and unsafe driving conditions.
The average cost for diagnosis of steering problems on an Audi Q5 is usually around €80–€150 at a specialist garage, including code reading and visual inspection. For common repairs such as fixing minor leaks, replacing hoses or freeing up a seized U-joint, you will usually pay between €250 and €600. Replacement or reconditioning of the steering pump or steering rack can range from about €600 to over €1,200, depending on the brand (OEM or reconditioned) and labour costs. Electrical problems (sensor/module) are often in the range of €300–€800 including programming.
Steering problems on an Audi Q5 reduce control over the vehicle, especially in sudden evasive or emergency braking situations, because the steering becomes heavier or may suddenly bind or free up. Noises, play and vibrations in the steering can distract the driver and undermine confidence in the car, which can lead to more cautious or, conversely, more restless driving behaviour. Electrical faults or loss of power steering increase the stopping distance in bends and make precise steering corrections more difficult, especially at higher speeds. Leaks or a faulty pump also cause inconsistent steering response, making it harder to judge cornering behaviour and stability.
Yes, preventive maintenance clearly helps to prevent or delay steering problems on an Audi Q5. Check at least once a year the level and condition of the power steering fluid, and the hoses and connections for leaks, and use only fluid approved by Audi. Regularly inspect the U-joint and steering column for rust and dirt, especially if the car is often driven in wet or salty conditions, and clean/lubricate them in good time. If you notice unusual noises, heavier steering or play, have a diagnosis carried out immediately to prevent more serious damage to the pump or steering rack.
