My big brother in Afghanistan just sent me his 2000 Audi A4. As it's been sitting for over 2 years, I have a feeling I'll be spending a lot of time on here getting answers and advice!

I've driven it for a week, and now all of a sudden there is a REALLY loud groan when I turn the steering wheel the slightest bit. The Power Steering fluid level is fine. What should I look for next? Is it still OK to drive while having things checked?

 

If your fluid is full , check the connections of the power steering suction side. There is a good chance there is air leaking past the hoses & clamps!
Does the fluid look like there is a lot of bubbles when running?

 

Thanks. While I am trying to check that out, is it ok to drive the car to work? Or should it not be driven at all until this is resolved?

 

If for some reason fluid is not getting into the system I would not drive it. You could damage the steering system. Also, note that Audi requires a certain type of power steering fluid and if the wrong fluid is used it will create problems.

 

You will need CHF-11S for the steering system. It would probably be best if you can get it repaired as soon as possible.
