Mechanics is a relatively Cartesian field. However, if there is indeed a concern that is sometimes complex to explain, it is an unstable idle or loss of acceleration. Whether it concerns a Volkswagen Golfsvan, or any car model. However, we are here to help you. Indeed, the cause can come from a good quantity of engine block components, even electronic. To detect the origin of the breakdown of your Volkswagen Golfsvan, it is necessary to follow a strict method. But first, let's see the symptoms of a faulty idle.
Idling problem on a Volkswagen Golfsvan: symptoms
Un unstable idle close to stall . This is undoubtedly the most recurring concern in slow motion. This feeling that the engine may stall while driving at a normal speed, or that the Volkswagen Golfsvan grazes . It also happens that the vehicle stalls. In this case, it is really dangerous for the motorist. In this case, don't wait too long to worry about it. We invite you to make your own diagnosis via the next paragraph. We can also understand that the Volkswagen Golfsvan has a concern for acceleration . No report this time with a concern for idling. Losses of power and acceleration holes can occur for many causes. We must avoid confusing these two phenomena. We suggest you read our posts related to power losses.
Volkswagen Golfsvan: developing a diagnosis to understand the origin of idling
We need to start by performing several relatively easy checks, just before going into more detail.
Idling of the Volkswagen Golfsvan: exhaust fumes.
A black smoke escapes from the exhaust. This generally means that the air and fuel mixture is bad. But also that the air filter is obstructed. In both situations, a problem of idling can occur on your Volkswagen Golfsvan. A White smoke escapes from the exhaust. In this case also it may be due to a fault. White smoke is usually water vapor. It is therefore likely to be an intake or cylinder head gasket concern.
Checking the engine block components
As we said, a problem of idling on this Volkswagen Golfsvan can come from many points. You should therefore take the time to inspect the engine block carefully. On the other hand, it is recommended to be very careful and not to touch the components of the engine block too much, because it can aggravate the malfunction or conceal the nature of the problem. We suggest of course going to an auto repairer for a more in-depth audit. Here are the elements to check point by point.
- The first thing to do is check all hoses . The latter can be perforated or even detached.
- It will also be necessary to check the sensors and sensors of your engine block. However, it is complex to check that they are working properly. Tutorials are easily found on youtube, and this often requires electronic devices.
- Perform a check of pressures hydraulic. Again, pressure tests require suitable tools.
Idle malfunctions are common but are complex to recognize. A visual check on the Volkswagen Golfsvan makes it possible to have an idea, but it is preferable not to tackle amateur DIY.
