Seeing the dreaded “Gearbox gearbox malfunction you can continue driving” message on your Audi dashboard can be pretty unnerving, especially if you’re not exactly sure what it means.
In this article, I will discuss the message’s meaning, the leading causes, and what you should do about it. Let’s get to it.
What Does “GearBox Malfunction” Mean on an Audi?
The short answer is, The “gearbox malfunction” message is a warning light on your Audi dashboard that means the PCM (Powertrain Control Module) has detected that there is a problem with the transmission in your car.
This is usually due to either a mechanical or electrical issue, both of which can cause serious damage if left unchecked.
Most Audi’s are equipped with the S-tronic also known as the DSG (Direct shift transmission) which is a dual-clutch transmission. It is a type of automatic transmission that allows for both manual and automatic operation.
Although this transmission is good and shifts pretty nicely, As a mechanic, I can tell you that is transmission requires a lot of maintenance and is prone to problems over time if not serviced.
Unfortunately, this is a common problem with Audi’s especially the S-tronic and Multitronic gearbox.
What Causes the “Gearbox Malfunction” on an Audi?
Now, let’s look at the possible causes of gearbox malfunction in an Audi:
1. Failed Mechatronic Unit
The mechatronic unit is a part of the gearbox that acts as a controller for all of the other components.
The mechatronic unit generates hydraulic power from electronic signals to operate your gearbox.
It can fail due to various reasons such as age, wear and tear, or neglect.
When it comes to Audi gearboxes this is a common failure and it’s one of the most common causes of the “gearbox malfunction you can continue driving” fault message.
2. Bad Gearbox Connector
The gearbox connector is a small plastic housing that connects the gearbox to other electrical components.
It allows electricity to flow from one component to another, allowing them all to communicate with each other.
If this connector breaks or becomes damaged in any way, it can cause problems with your gearbox operation.
Fortunately, this is also a common cause of the dreaded gearbox malfunction fault and it is much cheaper to replace than the mechatronics unit.
3. Faulty Transmission Control Valve
The third most common cause of the “gearbox malfunction” fault message is a faulty transmission control valve.
This valve controls the flow of transmission fluid through your gearbox so that it can be shifted into different gears.
If this valve stops working properly, it can cause problems with shifting gears or simply make your car unable to move at all.
This is also pretty common and here is the part number You need to order:
VW/Audi Part Number: 4h0121671d.
4. Cracked Transmission Filter Housing
The fourth most common cause of the “gearbox malfunction” fault message is a cracked transmission filter housing.
This is part of your Audi’s gearbox that filters out contaminants from your transmission fluid before it goes into your gearbox.
If this filter housing has a crack due to hitting a stone or wear and tear then it cause your Audi to leak as a result of the leak you will get a gearbox malfunction error.
5. Damaged Clutch
The final most common cause of the gearbox malfunction error message is a damaged clutch.
The clutch is part of your transmission that allows you to change gears and it works by pressing down on a flywheel using hydraulic pressure.
If this flywheel is damaged then it can’t get enough pressure to work properly so when you push down on your gear lever nothing happens.
Audi “Gearbox malfunction you can continue driving” Symptoms
Other than the warning message on your dashboard there are a few other symptoms that can help you to diagnose the cause of your gearbox malfunction error.
- No Reverse
- Poor Transmission shifts
- Jerking when changing gears
- Gear slippage
- Strange noises
Whether you have an Audi a3, a4, a5, q5 or q7 or a7 the main causes and fix are the same.
How to Fix and Reset the Gearbox Malfunction fault?
Since there are a few things that can cause this fault message, as an auto tech, I recommend that you get your Audi scanned with an OBDII scanner to see what error codes are stored in the system.
You can take your vehicle to an independent Audi specialist or if your car is still under warranty you can take it to the dealer.
