Real Diagnostic Results: Audi A5 DPF Pressure Restored!
When a Diesel Particulate Filter (DPF) becomes saturated, restricted exhaust flow causes high backpressure, reduced fuel efficiency, limp mode, and long-term risk to your turbocharger.
Instead of guessing, we rely on precise digital differential pressure testing before and after servicing:

• BEFORE: 99 mbar backpressure — high filter restriction causing severe exhaust restriction and warning lights.
• AFTER: 33 mbar backpressure — optimal pressure drop restored, allowing proper engine breathing, improved throttle response, and smooth ECU operation.

Symptoms Your DPF Needs Attention:

• DPF or Check Engine light illuminated on the dashboard
• Sluggish acceleration or vehicle entering "Limp Mode"
• Frequent, incomplete automatic regeneration attempts
• Noticeable drop in fuel economy
