I have a 2006 A6 3.2L and I'm throwing a check engine code. The problem was traced back to this part, but I don't know what its called so I can't find the replacement part. It has a vacuum line on the left, top-side and an plastic actuator arm on the bottom. See the 2nd photo. The arm is suppose to snap on a plastic ball but it keeps popping off and then the check engine light come on again. So far, it seems to run ok, but I want to replace it. Its under the top vacuum in the 1st photo.
Any help would be helpful.

Thanks,

I think this thread that was just started has some information that you could use.

 

Thanks, but I think the part in this link is the one in the 1st photo circled. I'm talking about the part below the one circled in the 1st photo. You can see it better in the 3rd photo. You can see the problem in the 2nd photo. The arm is supposed to be snap on the plastic ball you can see, about 1/4" below the arm.

Thanks,
Dave...

 

Nobody knows what this part is called?

It's the variable intake actuator arm. If it's the socket on the arm that is the problem you can get a new billet aluminum one to replace the plastic one you have. Do a google search for variable intake manifold actuator.

 

OK, it is called a Drive Unit, and the part # is 06e-133-159
But I still can't find this part available online. I can find this part number with an additional letter added to the end, but those parts are for different years of Audi's. Mine is a 2006 A6 3.2l Quattro.
Anyone know where I could get this part from?



Thanks,

That part number is correct.

A lot of the parts are shared across different models that also feature a 3.2L engine.

As a matter of the fact the B7 A4 shares the same 3.2l engine (BKH) as your C6 A6.

 

There are no more of those 06E-133-159 or 159A's left any longer. Audi now sells that vacuum diaphram actuator with the air distribution/intake runner that the diaphram attaches to as an assembly. As you said, although that same BKH engine is used for both the A4 and A6, one parts diagram shows the diaphrams as separate with their own part numbers (the A4) and the other doesn't (A6), but both engines end up using the 06E-133-125K or 06E-133-126K intake runners depending on if it's the left or right side that is needed.
