2009 BMW M3: Another day, another E-warning

October 13, 2009

On Sunday I asked the question, "Maintenance Reminders: Are they making us lazy, or are they keeping our cars better cared for?" and there were mixed results. Mostly, though, you thought as I do: It's best to be aware, but at the end of the day, having a computer tell you what to do is a handy back-up.

Trouble is, sometimes you encounter a problem soon after taking preventative action. For example, Friday night, some 48 hours before this warning, I checked the tire pressures on the M3 before a slightly spirited run through SoCal (which we'll get to in another post).

At this reading the driver side rear tire read 28 psi instead of the 35 the door sticker wanted. I gave it a visual inspection, rolling the car back and forth, saw nothing hit the closest gas station, got back up to 35 psi, and then drove the 4 miles home.

The M3 is at Stokes now, we'll know more soon.
