Introduction
Produced since 2001, the Vauxhall Vivaro is a popular choice among commercial vehicle users in the UK and beyond. Famed for its reliability and sturdy build, the Vivaro is the quintessential light commercial vehicle. In this blog post, we’ll focus specifically on the Vivaro 2.0 CDTI – a model renowned for its powerful diesel engine and its energy efficiency.
Despite the model’s sturdy reputation, some common problems may affect your Vivaro’s performance over time. Let’s explore these issues in detail and uncover solutions to keep your vehicle in top form.
Common Problems with the Vauxhall Vivaro 2.0 CDTI
1. Turbocharger Failure
The turbocharger is a crucial component of the 2.0 CDTI engine, boosting its power output. However, it’s also a part that’s prone to failure, typically due to oil starvation or foreign material damage.
- Solution: Regular oil changes are paramount in avoiding turbocharger failure. It’s also important to regularly check and clean the turbo system, ensuring it remains free from harmful foreign materials.
2. EGR Valve Issues
The Exhaust Gas Recirculation (EGR) valve reduces the amount of NOx emissions produced by the engine. However, over time, soot can build up and cause the valve to stick or fail.
- Solution: Regular cleaning of the EGR valve can prevent this problem. If cleaning doesn’t work, a replacement may be necessary.
3. Fuel Injector Problems
Fuel injectors play an essential role in the engine’s combustion process, and issues can result in a drop in power and fuel economy.
- Solution: Cleaning or replacing faulty injectors can resolve this issue.

Advanced Troubleshooting Tips for Vauxhall Vivaro 2.0 CDTI
In some cases, you might need to delve deeper to identify the cause of an issue in your Vauxhall Vivaro 2.0 CDTI. Here are some advanced troubleshooting tips for the most common problems:
1. Turbocharger Failure
To effectively troubleshoot a turbocharger failure, you must first understand the symptoms. Some common signs of turbocharger failure include:
- A noticeable lack of power
- An excessive amount of smoke from the exhaust
- A loud whining noise when accelerating
Advanced Troubleshooting Steps:
- Inspect the Turbocharger: Examine the turbocharger for any obvious signs of damage or oil leaks. If any components are damaged or if there are signs of oil leakage, it’s likely that the turbocharger needs to be replaced.
- Check the Turbo Pipes: Turbo pipes can often become clogged with oil, leading to a failure. Be sure to check these pipes for any obstructions.
- Monitor Oil Pressure: If the turbocharger is not receiving enough oil, it will not function properly. Use an oil pressure gauge to ensure that the oil pressure is within the specified range.
2. EGR Valve Issues
Some common signs of EGR valve issues include:
- Poor engine performance
- Check engine light is on
- Rough idling
Advanced Troubleshooting Steps:
- Check for Error Codes: Use an OBDII scanner to check for any error codes. An EGR valve issue will typically generate a P0400 to P0408 code.
- Clean the EGR Valve: Remove the EGR valve and clean it thoroughly with carburetor cleaner. After cleaning, re-install the valve and see if the problem persists.
- Test the EGR Valve: If cleaning does not resolve the issue, you might need to test the EGR valve. This can be done by applying vacuum to the valve and checking if it opens properly.
3. Fuel Injector Problems
Common symptoms of fuel injector problems include:
- Engine misfires
- Poor fuel economy
- Difficulty starting the engine
Advanced Troubleshooting Steps:
- Perform a Fuel Injector Balance Test: This test can help identify if one or more fuel injectors are not working properly. The test involves measuring the pressure drop for each injector and comparing it to the others.
- Inspect the Fuel Injectors: Check the injectors for any signs of damage or leakage.
- Clean the Fuel Injectors: Use a professional fuel injector cleaner to remove any deposits that might be affecting the performance of the injectors.
Upgrading Your Vauxhall Vivaro 2.0 CDTI
Beyond just maintaining your vehicle and addressing common issues, there are also upgrades you can consider to enhance its performance and longevity. Here are a few suggestions:
1. Engine Control Unit (ECU) Remapping
ECU remapping can help optimize your engine’s performance, potentially providing increased power and torque, smoother throttle response, and improved fuel efficiency.
2. Upgraded Intercooler
An upgraded intercooler can enhance the efficiency of your turbocharger, leading to better performance and potentially extending the lifespan of the turbocharger.
3. High-Flow Exhaust System
A high-flow exhaust system can reduce back pressure and enhance power output, as well as providing a more satisfying sound.
Conclusion
The Vauxhall Vivaro 2.0 CDTI is a reliable and efficient commercial vehicle that can serve you well for years. However, like all vehicles, it can face its share of issues. Awareness of these common problems and how to handle them can significantly increase your Vivaro’s lifespan.
