    Hi everyone. My journey continues, i feel like problems with my a6 will never end...

    It's an EURO6 and it's smells like euro 1... When parked in garage with open garage door and drivers door, i feel a soot smell...

    0. No error codes on tester (OBD 2) and no lights on board
    1. No smoke
    2. Super HIGH consumption on IDLE (at 830 RPM), 3L / h (when normal is 0.8L / h)
    3. Soot smell from exhaust

    P.S. 5-10 minutes after regenerantion, the smell from the exhaust is like flowers, but then soot smell comes back...
