Audi Chassis Codes?
I have a 2002 Audi A6 Avant Quattro with 3.0 engine. I am getting the following codes.
P0421: Warm Up Catalyst Efficiency Below Threshold (Bank 1) C06EE: Unknown code C0759: Unknown code I am not worried about the P0421. I am worried about the Chassis codes and cannot find anywhere that will explain what they are. I just had a local guy change all the belts and I am afraid something got screwed up. Does anyone have any idea what the chassis codes mean and they cause? |
What tool are you using to get these C-codes?
|
BTW....
Chassis codes are in your VIN number so if you using vagcom you will see them, if so don't worry. |

I ran with the error for at least 18 months and then was shocked at my fuel efficiency gain when I finally did replace my linkage armatures. Oh well, that money is long gone. Pull your engine cover off and see if your armatures are broken. Very inexpensive 15 min fix. |
A4 Phil are you taking about the manifold change over valve link arms?
Armatures are in electric motors, vacuum actuators move arms or levers. |

I changed both the motors and the levers. One motor had gone bad and both levers had snapped. The bad motor simply would not maintain pressure.

You're extremely lucky the rods hadn't frozen in the manifold….99% of the time that is the cause of the links or the vacuum motors breaking.

My P0421 code cleared up when I replaced my linkage armature. Not sure if that is a rule or a coincidence.

Could you find a picture of what needs to be replaced for this?
https://www.audiworld.com/forums/sho....php?t=2852103 Caveats, I am not familiar with the 3.0 engine, and I did not own my VAG at the time so I was relying on the old replace a part and drive and see if the code clears. In this case, the CEL cleared and when I did return to my mech, the code was no longer present... then I moved on to vacuum issues later. :-) |
