Hello all bits arrived today and I have fitted the pipes, I am not sure of where the scuttle drain should be routed I initially routed it around the air intake and to the front strut however on testing it the aux belt was covered in water please see the photo, so I then routed it behind the passenger side headlight, it's hard to know where it was initially routed too, does anyone have any suggestions or photos for reference

Nearly right.....It goes around the other side of the large black plastic air filter down pipe (runs down and parallel with it) and the open end should be right over (in line) with the unused webasto holes in the engine undertray which allows the water to drain away easier . Use a large black tie wrap to secure the two pipes together... Audi did originally.

Hi all--could use some help. I've just adjusted my shifter cables (which I'll kvetch about on another thread) which made it clear that water's been in my engine bay, if the general state of the place wasn't enough to go on.
I have drains on the left and right to match the bonnet, and one coming off the scuttle tube--am I missing any? As for the right side drain over the tower selector, it was aligned as in the picture below:
It's really difficult to see where it needs to be to match the bonnet drain on my car (03 plate 1.6), but I would think that the arm holding it to the ABS module bracket should be upright, like so:
But then there's John's helpful underhood photo that shows his is aligned at an angle toward the firewall (and covering the tower selector, which is the thing I'm trying to protect here):
Thanks in advance for helping me begin the process of resolving the rather shocking conditions under my bonnet.

My car is in the sick bay at the moment so I can easily get pictures.
O/S bonnet drain
N/S bonnet drain
Plastic scuttle drain
Aluminium scuttle drain, take a good look at this one, it does splash drips onto the tower (or it did in my case)

Cheers Phil. Love the ersatz drain solution on the other side of the scuttle!
