1) What are you guys using as a breaker bar for getting your wheel lugs off? I'm afraid of breaking that POS in the jack kit.

2) What is the difference between my oil temp gauge on the lower left on my instrument cluster and the temp gauge in the top center of my instrument cluster that seems to never move regardless of driving habits, outside temp etc.?

I use my decades old Craftsman 1/2" drive 16" long breaker bar.

The lower left is oil temp and it moves especially in hot weather long drives.

The upper gauge is coolant temp and is cpu controlled to stay in the center during modest temp changes. Audi was getting too many complaints when the temp gauge was a true reading gauge.

...despite the length of your torque wrench, (which you should be using to make sure your lugs are torqued correctly, IIRC it's 85 ft lbs), don't use it as a breaker bar.

is a service center to have the wrench tested and calibrated.

so much recently and I always have to remind them:)

so it's there in case of a flat. It works okay, but well serves the unique purpose of easy stowage for emergency use, so I accept its limitations. Always hand torque at 89. Never calibrated, but I use mine 6 times a year or so since new 3 years ago so hope it's close enough.
