You could find yourself with the steering wheel locked for no apparent reason as you prepare to take the wheel of your Audi A4. This typically happens, and in most situations it is not very serious. However, be sure to follow the steps we will speak about with you in in an attempt to find the remedy as simply and quickly as possible.
Before answering the question, we will first point out you how the starter mechanism works.
How the steering wheel of my Audi A4 works
First, the starter switch consists of two components.
- The cylinder of the lock in which you insert the key to turn it
- The electronic switch behind it. It gives the electrical impulse to start your Audi A4’s engine as soon as you turn the key.
When should it be changed?
Three cases may justify the need to change the switch on your Audi A4:
- The switch on your steering wheel was damaged or forced, in most cases because someone tried to steal your car.
- The switch suddenly failed and no longer functions at all.
- The switch on your Audi A4 reveals signs of weakness, there is a small delay between the time the engine starts or you have to press the key very hard.
Check thoroughly your steering wheel with your Audi A4’s manual to see if the switch is made of one piece or if the two elements (lock cylinder and switch) are separate. Indeed, it is possible to exchange only the out-of-service element, which is more economical. You will likely need to spend about a hundred euros if you use a garage, between 20 and 50 € if you change it yourself.
Now to the points:
How do I unlock the steering wheel of my Audi A4?
On a car, locking the steering wheel when stationary is a safety feature against theft. The steering wheel can only be unlocked by inserting the matching key into the vehicle.
Insert the key into the switch. Your steering wheel has almost certainly been locked since the last time you removed the key from the switch.
To unlock the steering wheel, just turn the key to the right and you can start the engine of your Audi A4. Try without forcing, in mechanics, it is hardly ever good to force so act carefully on the steering wheel and the key until you come across the unlocking point.
Maneuver the steering wheel, if your key is locked, move the steering wheel in the direction it wants to move and your key will then simply turn. Be careful, you must be more or less coordinated when you turn the steering wheel and the key of your Audi A4.
Do not shake the steering wheel too hard. If you force too hard, you may ruin the switch pinions, which will permanently block the steering wheel on your Audi A4. If this still doesn’t work, try to remove the key just a little. The plan is to find a position that would facilitate it to turn. Try one or two millimetres less depressed.
If you can start, your key is worn out. It would consequently be wise to change it quickly.
It is also likely that your switch may be seized. In the event of a blockage, it may necessitate a little specific anti-seize agent. Send one or two splashes into the slot of your Audi A4’s switch and then try to insert the key again. Play it gently to use product all over it.
Also, just check that your key is not damaged or blunt; if the teeth are no longer as they were in the first place, they will no longer be able to move the pinions of the cylinder on your Audi A4’s steering wheel.
If the problem originates from your key, remember to take your duplicate in order to make another copy and thus have two keys that are in working order for your Audi A4.
As you have read earlier, the main causes for a steering wheel lock are a damaged key or a jammed cylinder. In automotive mechanics, the majority of breakdowns or malfunctions are due to parts that are poorly or not maintained. Keep them in good condition by simply cleaning them regularly and also by taking care of them to maximize their life span.To discover more tips on the Audi A4, take a look at the Audi A4 category.
