[V8] Sunroof woes

[Scott Simmons]

I dug out the sunroof motor that came in the trunk of my car.  It looks 
similar to the one I have installed but carries a relay attached to the 
sunroof where you can see that mine

does not.  The family album shows the one in my car to be a later model 
motor?  And since the relay holder is on the cover, I assume that the 
cover too is from a later model V8.  I can only guess that the previous 
owner tried to jury rig a later model motor into a earlier model harness 
and ended up with spare wires (Gee, ya think?).  The motor in the trunk 
was 443 877 795B.  Which ETKA says is for models up to 44-L-15000.  
Since I have a 44-L-013222, I can only assume it applies.  Cannot see 
what number is on the motor in the car.

Motor in hand:  has a 5 pin relay.  Wires come out of relay and up into 
4 wire plug in (red/blue, blue, red/black, red/yellow) with an extra 
red/blue sticking out of the harness.  The two red/blues have been cut 
as it appears that they connect where the DIY crimp connector is in this

So why the change?  Why do later model V8's (or whatever model the motor 
is from) have a relay that has twice as many pins?  I'll take another 
look over the weekend, but that one crimp-connector appears to be the 
only change in the OE harness so I'll plug in this motor and see what 
happens.  I can only assume it's bad.

I want to take a baseball bat to people who crap like this.  Just 
replace it with the right part and you won't have to "make" it work and 
you will have a functioning sunroof again---not one that continuously 
wants to retract.  The same wiring genius is the one who probably did my 
window wiring---only the driver's door works: the passenger's will 
sometimes go down but not up, the rear ones never work.  All the wires 
in the door jambs appear to have been crimped before.  I'm gonna have to 
go clean up someone else's mess...

But then again, the car shines up really nice 
(http://i10.photobucket.com/albums/a143/indischrot/audi/v8frontleft.jpg) 
and drives like a dream.  Now, someone out there make me a 25mpg 
plug-and-play magic box...
