B5 Passat ABS Issue, Input Appreciated

Question...if I'm getting intermittent ABS/Brake/TC all lit (plus three beep chime), increasing in frequency over a couple months, would the ABS module be first area of focus, after physical connections? See below

I think so. Those Bosch 5.3 ABS modules are rather notorious...

I think I'll track one down soon to install and code as needed.

Take apart and re-solder the legs on the crummy solder joints.

...a good idea... Most likely, I'll get a warranted refurb...and core the old one, unless I get the time to bench repair it at work.

Guys, I opted to core-exchange through Cheap ABS. The major faults went away after replacement, but I did register a wheel sensor fault. The sensor was pretty oxidized and cruddy, so I cleaned it and have no brake faults, at this point I'll update as I put on a few miles.
