This Audi came to the shop struggling with a persistent P2002002 fault code. After diving into the diagnostics, we identified the culprit: a completely choked EGR cooler.
The Problem
As you can see from the photos, the cooler was entirely blocked by AdBlue crystallization. This isn’t just bad luck—it’s a design flaw we’re seeing more and more across these specific models.
The Solution
Replacing these is an intricate, “surgical” job, but we didn’t stop there. To ensure this Audi stays on the road for the long haul, we performed:
• ✅ EGR Cooler Replacement
• ✅ Full Timing Belt Service * ✅ Major Vehicle Service
• ✅ Custom AdBlue Solution (to stop future crystallization in its tracks!)
The Result
Two weeks of real-world testing later, the car is running flawlessly. Another happy customer is back to worry-free driving from A to B! 🚗💨
