What Causes Your Volkswagen’s Electronic Gear Selector to Stop Responding?
The electric gear selector is an innovation that uses the electric signals sent to the transmission rather than the mechanical linkage which differs from mechanical gear shifter. This enables easy gear changing, comfort while driving and increases connectivity in terms of safety solutions.
However, when the electric gear selector fails to work then a stressful situation is created. One may fail to change the gears either in Drive, Reverse or even in parking mode and end up being locked inside the car.
How Does the Volkswagen Electronic Gear Selector Work?
The electronic gear selector works in conjunction with the transmission control system instead of mechanically.
Many parts interact with each other and are used during the process:
Electronic Changeover Module.
Transmission Control Module (TCM)
The car's battery charging system.
Wiring harnesses and connectors.
Brake pedal switch.
Shift lock mechanism
Low Battery Voltage
The electrical system is an important element in new VW cars. With the depletion of the power supplied by the battery, electronic modules will be unable to communicate with each other.
Symptoms of the problem are:
Gear selection failure after turning the ignition.
The lights go on at once on the car's dashboard.
Slow engine cranking.
Irregular function of electrical accessories.
Faulty Gear Selector Electronic Module
There are sensors in the electronic switch gear and they interact with the vehicle control system. Like any electronic gadget it could fail due to the wear and tear of some of its parts.
Some of the signs of a malfunctioning gear selector module include:
Gear shifting occurs
Money is not released until the supplier is changed.
Gear indication flashing
Random shifting problems
Problems with the Transmission Control Module
TCM is referred to as the main component of the transmission. It receives data from different sensors and uses that data to shift the gears of the transmission.
Problems that can arise from a faulty TCM include:
The car is stuck in one gear.
Failure to shift into the Drive and Reverse gears.
Warning messages appear on the line or window of the instrument cluster.
Fault with Brake Light Switch
There are certain models of Volkswagens where the gear selector is supposed to stay in Park until the brake is pressed to release it. This feature works only if the brake light switch functions correctly.
Braking problems might arise because of brake light switch failure:
The gear selector cannot exit the Park position
Problems with occasional shifting
Warnings about the brake system on the dashboard
Problems with Wiring and Connectors
In order for the electronic gear selector to function there should be communication between the different control modules and such a connection can be disrupted due to faulty wiring or loose connections.
Causes for wiring problems can be:
Corrosion
Water leaks
Pest damages
Overheating
Loose electrical connectors
Software Problems
The software is just as important in a modern car as the hardware. In some cases problems with software in the electronic system might cause shifting problems.
Possible causes include:
Replaced battery
Voltage changes
Corrupted software
Update of the control modules
How Professionals Diagnose the Problem
The problem is much more than just replacing the gear selector since there are many electronic components used for communication with each other.
Typical procedures by the engineer include:
Identifying the problem.
Testing the battery and its charging system.
Investigating wiring or grounding problems.
Testing the function of the brake switch.
Checking whether there is an update needed for the transmission control module.
Communications check between control modules.
Checking the state of the transmission fluid.
Doing mechanical transmission tests if necessary.
Prevention of Future Gear Selector Malfunctioning
Certainly, all electronic devices may break down but proper maintenance may help prevent any unpredictable malfunctioning of a device.
To avoid injury these preventive measures are necessary:
Do not hesitate to replace faulty batteries.
Keep your electrical connections clean and dry.
Observe Volkswagen's maintenance plan for the service of your transmission.
Do not postpone any indicator lights appearing on the dashboard.
If applicable install software upgrades offered by the manufacturer.
The electrical devices undergo diagnosis before any problem appears.
