FixDeviceProblems.comFailures of the particulate filter (DPF) on the Tiguan: symptoms and necessary interventions
The symptoms of a failing DPF on the Tiguan
Loss of engine power
When the particulate filter is clogged, the Tiguan's engine may experience a noticeable loss of power. This issue is often accompanied by an increase in fuel consumption.
Check engine light on
A faulty DPF generally causes the check engine light to illuminate on the dashboard. It is essential to have it diagnosed quickly to avoid damaging other components.
Excessive pollutant emissions
A clogged particulate filter can lead to an increase in pollutant emissions. This can result in a failure at the technical inspection or have a negative impact on the environment.
The common causes of DPF problems
Frequent city driving
The Volkswagen Tiguan, while performing well, often faces regeneration problems with the DPF when primarily used for short urban trips.
Fuel quality
Using low-quality fuel can lead to a rapid accumulation of particles in the filter, compromising its effectiveness.
Irregular maintenance
Insufficient maintenance of the engine and exhaust system can accelerate the wear or clogging of the DPF on the Tiguan.
Necessary interventions to resolve DPF issues
Forced regeneration
For a partially clogged DPF, forced regeneration can be performed. This operation requires specific driving conditions or the use of advanced diagnostic tools.
DPF cleaning
A professional cleaning can extend the lifespan of the particulate filter. This involves removing accumulated soot and ash deposits from inside the DPF.
DPF replacement
In cases where the particulate filter is too damaged or clogged, replacement is inevitable. Parts suitable for the Tiguan, such as those available online, ensure perfect compatibility.
Preventing DPF failures on the Tiguan
Adopt suitable driving
To avoid clogging the DPF, it is recommended to drive the Tiguan on sufficiently long trips at high engine speeds.
Use high-quality fuel
Choosing high-quality fuel, combined with cleaning additives, helps maintain the DPF in good working condition.
Follow maintenance intervals
Regular maintenance by a professional ensures the proper functioning of all components of the exhaust system, including the particulate filter.
Conclusion
Failures of the particulate filter on the Volkswagen Tiguan can be avoided through suitable driving and regular maintenance. In case of persistent symptoms, it is crucial to intervene quickly to preserve the vehicle's performance and meet environmental standards.
