Vauxhall Vivaro DPF Problems
If you own a 2011 Vauxhall Vivaro with a 1995 cc engine, you may be all too familiar with the frustration of encountering persistent problems. Specifically, some drivers have reported issues related to their vehicle’s performance and mysterious “check injection” warnings. In this article, we’ll delve into the problem, its potential causes, and explore potential solutions to help you regain control over your Vivaro’s performance.
The Troubling “Check Injection” Warning
For some Vivaro owners, the trouble begins when they hit speeds above 70 mph. At this point, the dreaded “check injection” warning rears its head, accompanied by a noticeable loss of power. While the van remains drivable, this issue can be more than just an annoyance, particularly when it starts occurring more frequently.
The Investigation Begins
Taking the Vivaro to a trusted mechanic for inspection is the logical first step. One driver did just that and uncovered a problem with the turbo wiring loom that had been poorly repaired. Upon fixing this issue, however, a new, more severe problem surfaced. The van began losing all power when reaching 50 mph, leaving the driver no choice but to stop and restart the engine repeatedly.
The mechanic’s efforts to address the issue included:
- Replacing the turbo boost pressure sensor
- Replacing the manifold absolute pressure sensor
- Replacing the vacuum pump
- Replacing the vacuum breather hoses
- Replacing the crankshaft position sensor
- Inspecting the turbo (finding no play or leaks)
Additionally, the van’s Electronic Control Unit (ECU) was sent for testing, revealing a concerning revelation: “components have been deleted, van had DPF and EGR delete.” This finding raised more questions than answers.
A Conundrum: Deleted DPF and EGR
The deletion of the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) components is a significant development. These are crucial components in a vehicle’s emission control system, and their removal can have significant consequences. It can result in non-compliance with emissions regulations and potentially cause performance issues.
The Search for a Solution
Despite the extensive efforts to identify and rectify the problem, the only fault code that consistently appeared pertained to the Turbo Boost Pressure. Frustratingly, this was the point at which the garage conceded defeat and returned the van to its owner, leaving them desperate for guidance.
Expert Advice and Professional Help
The complexity of the issue at hand may require expertise beyond what a general mechanic can provide. Some users suggest consulting a Vauxhall service centre or a professional who specializes in Vauxhall vehicles. These professionals have the specific software and tools necessary for a thorough diagnosis of Vauxhall-specific issues.
In conclusion, Vauxhall Vivaro DPF problems, especially when compounded by EGR and other issues, can be a perplexing puzzle for drivers and mechanics alike. While some have found solutions through comprehensive diagnostics and specialized expertise, the journey to resolution may involve consultation with experts who understand the nuances of Vauxhall vehicles and their emission control systems. For Vivaro owners, patience and persistence may be key in solving these challenging issues and getting their beloved campervans back on the road in optimal condition.
