DPF Troubles? Understanding Fault Code 5253 in Your TDI Volkswagen

Is your Volkswagen Passat, Golf, Jetta, or other TDI model plagued by the frustrating combination of an illuminated engine light and fault code 5253? This code points towards a problem with the DPF (Diesel Particulate Filter) system, specifically the “Diesel Particle Filter; Differential Pressure Sensor.”

Don’t worry, you’re not alone. At Eurotech Autohaus, we frequently encounter this issue and possess the expertise to diagnose and rectify it quickly and efficiently.

The Problem:

The DPF is vital in reducing harmful emissions from your TDI engine. It captures soot particles, which are then burned off during a process called regeneration. However, a faulty differential pressure sensor can disrupt this process, leading to the 5253 code and potentially impacting your car’s performance and emissions.

Melter Sensor: The Hidden Culprit:

In some TDI models, particularly older Golfs, the 5253 code can be caused by a faulty “melter sensor.” This sensor monitors the temperature within the DPF during regeneration. If it malfunctions, it can send incorrect data to the engine control unit, triggering the 5253 code and potentially preventing successful regeneration.


Besides the illuminated engine light, you might experience:

  • Reduced engine performance
  • Increased fuel consumption
  • Black smoke from the exhaust

While these symptoms might not appear immediately, addressing the issue promptly is crucial to prevent further complications.

Diagnosis and Repair:

At Eurotech Autohaus, our trained technicians leverage advanced diagnostic tools to pinpoint the exact cause of the 5253 code. We then analyze the DPF system, including the differential pressure sensor and the melter sensor (if applicable) to identify the culprit.

Depending on the issue, we might need to:

  • Clean or replace the differential pressure sensor: If the sensor is simply dirty, cleaning it might resolve the issue. However, if it’s damaged, replacement is necessary.
  • Replace the melter sensor: In cases where the melter sensor is the culprit, replacing it with a genuine VW part is crucial for proper DPF function.
  • Perform a forced regeneration: If necessary, we can initiate a forced regeneration to clear the DPF of accumulated soot and restore its optimal performance.
