My 2007 honda accord which was bought a few months ago,the outside temperature gauge has stopped working, also i noticed a week earlier a spot of oil on my driveway which came from the car near the drivers side. upon inspection couldnt see anything leaking, besides the temp gauge now not working is this an indication of a problem that needs to be attended to!

If you brought your car to Honda for service, they probably forgot to reset the maintenance reminder. If you took it to another shop, they probably did not know how to reset it. Anyway, the reset procedure is:

Put your key in the ignition
Turn the key to the II position for a couple of seconds
Then turn the key to the off position
Now push and hold in the odometer reset button
While still holding the odometer reset button, turn the key back to the II position
Hold for I think 10 seconds or so and your maintenance reminder light should reset it self.

Sounds like a leaking valve cover gasket. The parts are around $50 to do both cylinder heads from www.ecstuning.com. It's not a major issue, but it may be a sore point to a potential buyer.

I have the same problem 52000 miles on a 2006 525 i. I see some at the top of the engine near a square plastic cap. I cant even find the dip stick
