Have you seen any weird numbers showing up on your odometer display when you turn on the key. We have a 2005 Bettle TDI this occurs every now and then, the dealer does not know why.

What weird numbers? It could be a defect. Are you sure it doesn't say the maintenance message as listed in your owner's manual? That message should appear every time though.
