[V6-12v] Couple minor issues with 95 A6

[beattyr2003 at cox.net]

I just have a couple minor annoyances that I am sure others have dealt with on a 95 A6 Sedan/Wagon.

I actually have 2 of these cars, one a wagon, the other a sedan.  I am seeing the same issues on both cars.

1st issue is drivers side wiper blade lifting off the windshield at highway speeds, which is HIGHLY annoying in rain.  I have changed the cartridge and tried fiddling around with the arm a bit, even trying to bend it to apply some more downward pressure on the blade.  Seeing this issue on both cars, so I am assuming its a model problem and not an  individual car thing.  Anyone have any experience with this?

2nd issue is check engine light.  I know the usual culprit is the EGR port from the intake manifold to the EGR itself, and I cleaned that out on the sedan, but I am still seeing the light intermittantly.  Any other common reasons for this?  Obviously, it could be the EGR itself, but before I change that out, I want to elminate other potential easier solutions.  I haven't built an interface yet for the ODB I system in the cars, so I haven't pulled codes either.

Thanks for any help you guys can give.
