How to Deal With DME Communication Failure in Your Volkswagen
By Bavarian Performance Specialists March 14, 2019
The DME, or digital motor electronic, controls most of the functions within your Volkswagen’s engine. This component maximizes performance, reduces emissions, maintains reliability and keeps fuel consumption low. If you experience DME communication failure, you will experience problems with your engine.
The Function of a DME
DME sensors capture the data that influences the operation of your engine. The data collected includes the accelerator and throttle position, vehicle speed, air flow, air density and air temperature. This data is then calculated and converted into commands that are sent to the ignition and fuel injection systems. If the digital motor electronic sensor fails and delivers incorrect data, this can lead to damage to the engine and other important components.
Faulty DME Symptoms
A faulty DME will have specific symptoms that you can look out for. If you experience any of these issues it is important that you take your vehicle to a certified mechanic that is highly knowledgeable with the Volkswagen brand.
Check engine light
Your check engine light can come on due to a number of different reasons. When you take your vehicle to a certified mechanic they can run a diagnostic check with a specific scan tool. When your light is triggered, a code is generated. Your mechanic can find this code, and this will allow them to pinpoint the problem.
A faulty DME unit can cause your engine to misfire. Misfiring is usually random and this is due to the fact that the unit is sending incorrect information to the engine. Your vehicle will end up experiencing poor acceleration, increased fuel consumption and loss of power. If you experience misfires, you should have your car serviced immediately. Misfires can cause additional component failures.
When your engine isn’t receiving the data that it needs to run properly it can stall. Having your car stall while you are driving can be very dangerous and lead to a serious accident.
Your car won’t start
If the unit is damaged and no longer has control over the engine your car might not start at all. Usually, before this happens you will have issues starting the car, but it eventually starts after a few tries.
Replacing the DME Unit
If you have a defective DME unit, you need to replace it right away. The DME needs to be working properly to keep your engine functional and to keep you safe. Some Volkswagens have an existing warranty that will cover the replacement of the part if it fails prematurely.
Some DME unit failures can be caused by a minor issue, and this will allow the part to be repaired. In other instances, the unit will have to be replaced. The cost of replacing the DME unit varies and will depend on the specific model of your vehicle.
The best way to know if you are dealing with a DME communication failure in your Volkswagen is to have a certified mechanic perform a diagnostic check.
