Not a lot has been happening lately. Proudly I can say the S4 has been pretty problem free for some time now. That said, it kind-of feels odd when something isn't wrong.... so, you go looking for something to fix. In that past that can get me trouble so I figure I keep it simple. I put in my K&N Air Filter back when I first got my car, 80k miles or more ago, and I'm sure it likely due for a cleaning. If you have a K&N filter you know it comes in a cherry wood red like color, but mine was more of a charcoal gray.... clearly it needed to be cleaned. Ordered the cleaner and oil kit from Amazon and two days later went to work.....
Stopped by Achtuning to upgrade the ECU. After a hour of no success of re-flashing the ECU we found out my car had already be flashed with the APR software and was just in a "lock out" mode Finally got the APR software unlocked and it only cost $99 compared to $500.... thank you previous owner!
Changed the Oil and Oil Filter with Mobile 1 0w40
Installed PIAA Ion Yellow bulbs in the fog lamps.
