As soon as you slow down below a certain speed your car starts to graze and sometimes even the engine stops for no apparent reason.
So you tell yourself that this is abnormal. We want through this article to try to provide you with an element of answer in the idea of better understanding the failure. You can then probably go to the garage with more knowledge, so that the bill is less expensive to repair your Audi A6 while avoiding being ripped off.
Of course, if your Audi A6 stalls while driving at a high speed, do not take unnecessary risks, urgently call a professional. Keep in mind that if this were to happen at high speed, you would be in great danger.
Here are the different reasons that can cause your Audi A6 to stall at idle.
Different causes that cause your Audi A6 to stall at idle
First thing to take into account, and it may seem strange, but it happens sometimes: Do you use fuel all the time at the same pump? If so, this may be the cause. Car engines damaged by impure fuel have already been identified. Try to stock up elsewhere, and see if your problems persist. This is a rare occurrence but the effort is worth the effort when your Audi A6 stalls at idle.
If nothing has improved on your Audi A6, we will see the slightly more technical origins which are causing you problems.
Problems with the electronic parts which cause your Audi A6 to stall:
The first thing to think about then when your Audi A6 stalls at idle, the BSM box of your Audi A6. Did you discover that name? In a few words, this essential part, which is also called UCM (Engine Control Unit), or CM (Engine Computer), is a metal box which brings together a large number of electronic elements whose purpose is to capture electrical signals, process this data, and send information to the different parts of your Audi A6. In other words, it is a platform for managing information about your car.
Logically, if it were to malfunction, the consequences can be serious. A stopping motor can be one.
Aside from that, look at the engine speed sensor side, or the computer. The latter, like the BSM box, has this role of a platform for exchanging calculations and is therefore essential to the engine, and may result in your Audi A6 stalling at idle.
Another box probably targeted, the BSI box, which concentrates all the information from the multiple sensors of your entire car. It acts as a relay platform for all your computers. It can be compared to a computer motherboard. You can therefore understand how essential this part is on your Audi A6 ..
Speaking of sensor, also consider your PMH sensor. Its role is to send information to the computer with regard to the position of the pistons in order to calculate the engine speed, Conditions the fuel injection.
Last electronic part to watch, which can cause your Audi A6 to stall at idle, consider your alternator, which would no longer allow your Audi A6 to be supplied with current.
Lastly, because this case is much rarer, it suffices for just any wire or connection to be damaged, and your computer could no longer perform its function correctly on your Audi A6.
So here for the electronic causes. Now let's look more at the mechanical side.
Problems with the mechanical parts that cause your Audi A6 to stall:
In the first place, simply a dirty filter can disrupt the life of your engine. Remember to clean it frequently. The injection pump, or even the pressure regulator of your Audi A6, are also parts to maintain frequently.
Also probably involved the idle actuator when your Audi A6 stalls at idle.
Its role is to regulate the engine speed of your Audi A6 which will allow it to be adapted to the speed of the vehicle. This therefore has consequences on the engine that may hinder its proper functioning.
Another factor, rarer but also possible, the contactor of Neiman. This one we know without knowing its name, it is what makes it possible to block the steering wheel for safety when we turn off the ignition. If you feel an abnormal ignition time, it may be the cause of your Audi A6.
Here are the main origins, whether electronic or mechanical, which can cause your Audi A6 to stall at idle.
In a nutshell, first think about checking the simplest things, the clogging of parts, then then find out about the electronic parts probably in question.
If it was essential to embark on a DIY home, be careful what you do, nothing beats the expertise of a specialist.
