The Audi is being incredibly frustrating right now.
It's been sitting at my mom's house, which is 120 miles away from where I live, unable to start. A buddy and I pulled the starter off and took it to Autozone and it tested as dead. So we put a replacement one on, but it still wouldn't start.
I bought a replacement power steering pump from evocoupe1racing (Greg) for it, and it hooked straight up to two of the three hoses, but the filter-equipped banjo bolt for the third hose was too narrow for the pump. I then went to the Audi dealership and looked up the part number and eventually found what we believed to be the correct bolt. I ordered it from ECS Tuning and then had to go back home for New Year's.
Fast forward to this weekend. The bolt arrived over a week ago at my mom's house, so I came up this weekend to install it and then begin work on the starter. The bolt ended up being the exact same bolt I already had, so that was a bust. Failing that, I began trying to diagnose the starter. The voltmeter in the car was reading below 12 volts, so I jumped it with my Grand Prix. It wasn't going up quickly enough for my patience, so I took it to Autozone to get it tested. As expected, it needed a charge. They charged it for free and the battery tested as good. It's only just over two years old, so that's to be expected.
I moved on to the starter, but can't really figure out what's wrong. I have a battery that has tested as good, a replacement starter, and a new (within the year) ignition switch. This is incredibly annoying.
