Hi everyone, N8 very kindly scanned my car for error codes to try and get to the bottom of a problem that's mystifying all of the mechanics I know. The error codes were as follows: 000000 - SAE - Reserved by Document ISO 15031-6 P0000 - 006 - 2005 - Intermittent Freeze Frame: Fault Status: 01100001 Fault Priority: 0 Fault Frequency: 37 Reset counter: 40 Mileage: 0 km Time Indication: 0 Freeze Frame: RPM: 1984 / min Torque: 144.0 Nm Text: Kein MEASVALUE verfuegbar Text: Kein MEASVALUE verfuegbar Text: Kein MEASVALUE verfuegbar Text: Kein MEASVALUE verfuegbar Text: Kein MEASVALUE verfuegbar Raw, Form. N / A: 000 000 000 -------------- Auto HVAC Labels: 8E0-820-043.lbl Part No: 8E0 820 043 BL Component: A4 Klimaautomat 3233 Coding: 00000 Shop #: WSC 00000 VCID: 6CD392611C222C78EC3 1 Fault Found: 00716 - Air recirculation Flap Positioning Motor (V113) 41-00 - Blocked or No Voltage -------------- Does anybody know what the first error code is or have you seen it before? I've tried google and hit the translate button on a German forum and a Russian forum but am none the wiser. Although the guy who posted it on the German forum appears to be getting told off for deleting his DPF and remapping his car, and the Russian owner was told his car might have had a bad map on it. My problems are excessive black smoke, lumpy idle, hesitation at about 2,000 rpm (like a slight flat spot), very easy to stall when cold but seems okay once it's warmed up. I am desperate to get this sorted. Thanks in anticipation.
