🚗 Audi A5 AdBlue Fix! 🔧
We went out to this Audi with a P20E800 fault code (Redundant Pressure Too Low).
Even though the AdBlue tank was sitting at 80% full, the system was throwing a tantrum. Instead of playing guessing games or throwing expensive parts at it, we went straight for a software solution:
🔹 Pulled the ECU
🔹 Flashed the fix
🔹 Reinstalled & cleared the codes
Fast turnaround, zero guesswork, and a completely error-free dash! 🏎️💨
