I have a 2004 Golf tdi, to my understanding I have a fuel cooler but I don't see it. Is this correct and where is it? Does this need cleaning or maintenance?

Yes, under the pass side floor if auto, no cleaning. This is because you have a pumpe duse.
Later cars had a front mounted fuel cooler.

Read around the FAQ and you will find a wealth of technical info and how tos. Start here

What does it look like, there were no pix of it in those links?

Let me clarify, all ALH automatic transmision and all pumpe duse have a fuel cooler.

The mk4 body has it under the pass side, the mk5 body has a front mount fuel cooler.
