  I was driving hit a puddle of water, then all the sudden my power steering went out. I took it in to get looked at, and I'm being told it will cost several thousand dollars to fix the power steering. In addition, this vehicle has air in the suspension, but it now makes sounds when it lifts and takes a longer period of time to lift than normal. Something is effected in my suspension, as well. My vehicle only has 67,689 miles on it, and it should not be having power steering problems from driving through a puddle of water. Lastly, after calling in to Audi, they did a search for the warranty, and Audi did add an extended warranty on the power steering of 125,000 miles or 10 years, which ever…

This could have caused a fatal accident while I was driving my family the store.

  The turbo failed while driving the car at normal speed trying to enter freeway. Luckily I was able to get the car to the side of the road safely. The vehicle has always been serviced by Audi on prescribed intervals. After researching, I found a TSB on the oil screens that feed the turbos. The dealer (Audi Miramar, San Diego) told me this is not/was not a required repair and quoted me $16k to replace the turbos and replace the faulty screen. I ended up taking the car to another authorized Audi repair center and got them repaired for $9k. Audi needs to address this before someone has an accident.
