[Vwdiesel] A few TDI followup questions

[Val Christian]

Not just mass, but also moment.  The radius of the center of mass 
should remain the same, and the mass should remain the same.  This is
because a mass closer to the axis will have a lower linear velocity.

In theory, at least.  

Sorry, my spare fans are for A1s.

> Now that I have the TDI running, I'm finding all of the other little problems. One is that for some reason, a little section broke off the smaller of the two cooling fan's blades. I had the part, didn't know what it was, and pitched it somewhere. Now, of course, I can't find it to glue back in and the dealer tells me the blades are not sold separately, even though they are the worst plastic part I've seen in a VW. Wouldn't bother me, but the fan runs poorly being imbalanced. Anyone have a mangled fan motor with a separable blade they could be convinced to part with? I'm hoping the part is the same across the A3-A4 so I can maybe get really lucky and find on the a wrecking yard, even though I've never see a VW that new in the yards. I'm also thinking that maybe I can just unhook that fan for a bit. I presume they both run in the same circuit so one should cover the other somewhat.  
> The other is that I'm getting an engine code of P3130 19586. Bentley is silent on this one. I searched TDIclub.com and it turned up something about the EGR being out of whack. I do know that the EGR is running like 85%, and the MAF is reading ~500 when it should be at ~250 max at idle. I can't imagine that the MAF died while it was sitting in the garage for several months. I don't know that much about all of these parts yet. I guess I will soon....
