Hello,
Just so we are on the same page, is the relay you replaced located in slot #3 located right below the orange 40AMP compressor fuse, as shown in pictures in post #52 in the attached thread link, upper relay with # 370 on it.

I checked the fuses and there is no fuse in space #15 and #42 was 25A and it was fine.
I went to our local VW dealer and picked up a J329 relay replacement (p/n 4HO 951 253)* and installed it. Turned the ignition key and nothing. It's still not starting.
So far I have replaced the brake switch and J329 relay and still it won't start. Dang!
*the 4HO 951 253 was an updated part number for #8DO 951 253 according to the VW parts guy

You never did tell us if the brake lights work after you replaced the BL switch, so please let us know, ALSO, any chance of posting some pictures of the dash when you insert and turn on key ?

Yep, kind of why I had to open it too... After you do, ask yourself why they didn't redo it a bit and put the ECU's inside there instead of just thrown in the plenum with a few chastity belt brackets.

In 30 years it's been rare to actually encounter a relay fail. I can think only a couple of times in older cars, heavy duty or high current switching.
A quick scan of the car diagnostics from the entry & start auth module will yield the issue. Other than that you have to trace voltage through the relay base terminals (in-series chain) during an attempt to starrt (=PITA)

sounds like he might have a neutral/park safety issue, see if the P R N D S is all lit up, if it is Neutral safety issue car will never start, if it not still try this remove the ash tray in the front of the shifter there a small hole take a screw driver and push it in the hole push it down you should be able to move the shifter out of park put it in the N position and try to start... if that doesn't work Ill tell you how the try to activate the starter manually to test it, it might just be dead also...

Update?
Im guessing once vcds is hooked up you'll find the starter is jammed and you may need a new one. Also I have an 04 and I don't need to press the brake to start the car.
