What brand of power steering fluid does my car use and where can I buy it?

I had a new fule filter put on. About an hour later the trunk button went out. I had the fuses checked and they were fine.

I returned from running errands in the cold, parked and the next morning when I shifted into reverse it moved 3 ft and stopped. It is making a rattling sound when I shift into any gear as if it is not going into gear. It had no problems before this, didn't make any funny noises, shifted fine the day before. Please advise.

why is my oil crunchy?

The gear shift came off and I'm trying to put it back on. Does the white plastic piece have to be up or down when you put the shift handle on?

Can anyone please tell me if $1100 sounds fair for replacement of tie-rods and front left axel on an Audi A4 (year 2000)? Took 'er in for winterization and looksee today. Different repair show than I typically use. Moving to New England next month and want car to be up to the task. I was surprised to hear the tie rod ends were loose and falling apart and axel on front left side was bad. Does this quote seem fair (it includes alignment)? thanks!

Had my audi smog check now the ECU fuse keeps on burning up, the car only turns but does not start.
