Frequently Asked Questions

A common reason for a diesel vehicle to lose power is a clogged Diesel Particulate Filter (DPF). This occurs when the DPF becomes overloaded with soot, often due to underlying engine problems such as: Faulty EGR Valve: This valve recirculates exhaust gases back into the engine, and when it malfunctions, it can lead to increased soot production. Failing Glow Plugs or Injectors: These components play a crucial role in the engine's combustion process. If they're not working correctly, it can result in incomplete combustion and excessive soot. To protect the engine, the vehicle's Electronic Control Unit (ECU) will temporarily reduce power until the DPF is cleaned or the root cause of the issue is addressed. Other factors that can cause a diesel car to lose power include: Turbocharger Failure: A damaged or malfunctioning turbocharger can significantly impact engine performance. Fuel System Problems: Issues with the fuel pump, injectors, or fuel filter can disrupt the fuel supply to the engine. If you're experiencing power loss in your diesel vehicle, it's essential to diagnose the underlying problem and take appropriate action to restore optimal performance and prevent further damage.

Diesel vehicles equipped with AdBlue systems, introduced with Euro 6 standards, have a failsafe mechanism to prevent further damage. When the AdBlue system malfunctions, the vehicle will initiate a countdown, typically in increments of 1000, 500, 250, or 50 miles, after which the engine will become inoperable. Common causes of AdBlue system failures include: Urea Crystallization: Urea, a key component of AdBlue, can crystallize within the tank, obstructing the level sensor or pump. AdBlue Module Software Corruption: The AdBlue module's software can become corrupted, leading to malfunctions and incorrect readings, such as the vehicle's ECU believing there's insufficient AdBlue. Resolving these issues can be costly, often involving the replacement of the entire AdBlue tank assembly, which includes the module, pump, and sensor. In some cases, the cost of replacement may exceed the vehicle's value. AdBlue Delete: An alternative solution is to disable the AdBlue system entirely, known as an "AdBlue Delete." This allows the vehicle to operate without AdBlue, but it's important to note that this modification may render the vehicle non-road legal. If you're considering an AdBlue Delete, it's crucial to consult with a qualified technician to understand the potential legal and performance implications.
