The Best Fix for DME Communication Failure in Volkswagen

by europewpadmin November 6, 2020

Your Volkswagen is an intricate piece of machinery that can have problems arise at any point in time. With the large number of parts working together under the hood to bring about the powerful ride that you have come to love, it’s no wonder that you may be concerned when an unknown issue rears its head.

Take solace in the fact that most vehicle issues that will plague you are likely fixable and will not be long-lasting. With this in mind, it’s important that you take your Volkswagen into the shop as soon as possible when you have problems come up.

Problems with the DME communication system of your vehicle can be serious and should be treated as such. Take your car into a professional when necessary to get this issue fixed as soon as possible.

What is the DME system?

The DME system is short for digital motor electronic system. With the name spelled out, it may become more clear why this problem can be a serious issue. Essentially, the DME communication system uses sensors to capture certain data that is used to operate your engine.

To give perspective on the type of information that may be collected, when you press down on the accelerator pedal in your vehicle, an airflow valve opens a very specific amount. When it does so, a control unit for the engine needs to know that amount so that it can release the right amount of fuel into the engine.

The DME system captures that information which allows the control unit for the engine to release the perfect amount of fuel for the system to use. Data such as vehicle speed, air density, and even air temperature are all recorded and given to various parts of the engine that allow for certain actions to occur.

A faulty DME system can have serious consequences for your car as a whole, which is why it’s so important to understand the function of this system. Below are some of the common signs that something may be wrong with your Volkswagen’s DME system, and all signs should be used as a reason to take your car into the shop.

Signs of DME System Failure

Given the importance of this system to your vehicle, it’s only natural to assume that most problems that may arise will have easy to see symptoms. This assumption would be correct and spotting the below signs can be done quickly if you know what to look for:

Misfiring Engine

Should this system fail under the hood, it may not record how much the air intake valve has opened or it may not have sent the proper information to the control unit that releases fuel into the engine. If either of these things occurs, your engine may misfire as it has the wrong air to fuel mixture under the hood. This will sound like a coughing or sputtering sound.

Check Engine Light

Your Volkswagen’s computer is a smart system that can detect when things are wrong under the hood. If it detects this, the check engine light may turn on when it senses something wrong with the DME system. Anytime your check engine light turns on, it’s best to take your vehicle into a professional shop to get it switched off and diagnosed.

Your Vehicle Won’t Turn Over

If your DME system has completely failed or is sending the wrong information to the engine, your engine may not even turn over and fire up. Believe it or not, your vehicle needs a fair amount of information to even start, and without this, it may enter a no-start condition.
