Steering feel sensor problems often arise from a faulty power steering system, a failing steering feel sensor or broken pressure sensors. The result is always the same: increased steering effort, unpredictable steering inputs and unsettled handling. This not only makes your car tiring to drive, it can also create dangerous situations. If you recognise the warning signs in time, you can prevent a small defect from turning into an expensive repair.
What does the steering feel sensor do?
The steering feel sensor measures how much force you apply to the steering wheel and in which direction you turn it. This information is passed on to the control unit of the power steering, also called the power steering control unit. Based on that data, the system determines how much assistance to provide. If the sensor is not working properly, the control unit receives incorrect information. As a result, the power steering may provide too little, too much or no assistance at all.
With models such as the Seat Altea, steering problems are regularly reported. Owners mention heavy steering, whining noises and unpredictable steering behaviour. This is often a direct result of a failing sensor or an issue in the power steering system. As soon as you recognise these warning signs, it is wise to act quickly.
Why has my steering effort increased?
Increased steering effort means the steering wheel turns noticeably heavier than normal. This is especially noticeable at low speed, when parking or in tight corners. In many cases this points to a fault in the power steering system. The most common causes are:
- A low fluid level due to leakage or natural consumption
- Wear to components of the power steering system
- A faulty steering feel sensor sending incorrect signals
- Problems with the power steering control unit, which does not control the assistance correctly
- Broken pressure sensors that no longer provide accurate pressure readings
Once the sensor or the control unit fails, the system can no longer determine how much support you need. This leads to heavy steering or, conversely, to unexpected steering inputs. A whining or squeaking noise when turning the steering wheel is often an early warning sign.
Which warning signs point to steering feel sensor problems?
Steering feel sensor problems can reveal themselves in different ways. The symptoms may gradually get worse, but sometimes they also appear suddenly. Recognisable warning signs are:
- The steering turns heavier than normal, especially when stationary or at low speed
- Unusual noises such as whining, squeaking or groaning while steering
- Restless steering behaviour where the car responds less predictably
- Patches or traces under the car indicating leakage of power steering fluid
- Steering impulses that feel like the steering wheel springing back for no reason
These symptoms arise because the control unit receives incorrect information. Pressure sensors, for example, may transmit values that are too high or too low, causing the assistance level not to be properly matched to how you are steering.
How expensive is steering repair?
The cost of repairing steering feel sensor problems varies widely. It depends on the specific component that is defective and the type of car. Replacing a steering feel sensor costs between €150 and €400 including labour. For a new power steering control unit this can rise to €600 to €900, depending on make and model.
For pressure sensors, the price tag is often between €100 and €300. If it concerns a more general power steering problem, such as a leak or wear in the steering gear, the costs can increase further. A full system check and topping up the power steering fluid is usually cheaper and costs between €50 and €100.
If you ignore the symptoms for too long, the risk of consequential damage increases. A relatively simple repair can then grow into an expensive and time-consuming problem.

Can I still drive safely with steering problems?
Driving with a defective power steering system or failing sensors carries risks. Increased steering effort makes it harder to react quickly in an emergency. Unexpected steering impulses can throw you off line, especially at higher speeds or in slippery conditions.
With a completely failed power steering system, the steering wheel becomes extremely heavy, but steering remains mechanically possible. It is, however, tiring and requires a lot of strength. Parking is then almost impossible and small corrections take a great deal of effort. That is why the advice is to go straight to a garage at the first warning signs of steering feel sensor problems.
If the symptoms suddenly appear while you are driving, continue carefully to a safe place and have the car recovered or drive at low speed to the garage. Avoid busy roads and tight bends.
What can you check yourself?
Before visiting a garage, you can carry out a few simple checks yourself. These steps can sometimes already give you an idea of how serious the problem is:
- Check the power steering fluid level. The reservoir is usually in the engine bay and has a min and max marking.
- Look for leaks under the car, especially near the front wheels or under the bonnet.
- Listen for unusual noises when turning the steering wheel while stationary.
- Watch for any warning light on the dashboard indicating a problem with the power steering.
- Feel whether the steering is consistent while driving or whether there are sudden changes.
If you find that the fluid level is low, top it up with the correct fluid as specified in your car’s manual. If the problem continues or the level drops again quickly, there is probably a leak and professional help is needed.
When should you go to the garage?
With any warning signs of steering feel sensor problems, it is sensible to visit a garage. A mechanic can read out the system with diagnostic software and determine which component is defective. The power steering control unit often provides a fault code that points to the exact cause.
Do not wait too long to have the fault repaired. A defective sensor can cause overloading of other components, such as the power steering pump or the steering gear itself. This makes the repair more expensive than necessary. In addition, the safety risk increases as the symptoms get worse.
Look for a garage that has experience with the type of car you drive. Especially with electronic power steering and modern sensors, specialist knowledge is important for correct diagnosis and repair.

Frequently asked questions
The most common steering problems with a Seat Altea are heavy steering, whining or squeaking noises and possible leakage of power steering fluid. This often points to too low a fluid level, leakage or wear in the power steering system or steering gear. First check the power steering fluid level and look under the car for signs of leaks. If the symptoms persist, it is wise to have the car checked immediately, as it can pose a safety risk.
In a Seat Altea, steering wheel problems can present as heavy or unsettled steering, often accompanied by whining or squeaking noises. This usually indicates a shortage of power steering fluid, a leak or wear in the power steering pump or steering gear. Therefore first check the fluid level and look under the car for possible leaks. Have the power steering system inspected as soon as possible to avoid unsafe handling.
