Red light on maintenance required is on, what would that mean. Oil has been changed recently, approximately 45,000 miles on the car

VW fill the gearboxes "for life" which means it must be changed at "regular intervals as specified in the dervice manual"you could leave it as long as you want,but could cause problems later.(especially if the car is driven HARD.)the (VW)oil for the tiptronic gearbox IS expensive.

The light comes on every 10,000 miles to remind you to change oil and other required service. There is a procedure to reset the light, do a search on Toyota Maintenance Required light.

The light comes on at fairly short intervals ... even to let you know that you need an oil change. The mileage at which it comes on will depend on when it was reset last time. Here's a link to Yahoo Answers to turn the light off yourself.

This is a oil change reminder. Nothing fancy about, when you get your oil change go into the menu and click reset counter and it will go off. If there was something wrong with your car the check engine light would come on.

THE LIGHT COMES ON TO LET YOU KNOW WHEN MAINTENENCE IS COMING DUE OTHER THAN OIL CHANGES. SUCH AS, TIRE ROTATIONS, TRANSMISSION SERVICE, ETC. ROUTINE MAINTENCE ACCORDING TO APPROXIMATED MILAGE. IT SHOULD HAVE A BUTTON ON THE DASH TO THE LEFT OF THIS LIGHT THAT CAN BE PUSHED IN WITH A PEN TO RESET. REFER TO OWNERS MANUAL FOR SCHEDULED ROUTINE MAINTENANCE ACCORDING TO YOUR OVERALL MILEAGE

Maintenance Required is a light that comes on after a predetermined number of miles. For example, if the maintenance schedule Honda set for the car calls for an oil change at 3000 miles, a new fan belt at 6000 miles, and another oil change at 9000 miles, then the maintenance required light will come on every 3000 miles and stay on until it is reset by the dealer. Some people, especially those that do their own regular maintenance but don't have a way to reset the light themselves, find this an annoyance. But others find it useful and take their cars in to the dealer every time the light comes on, and they rest assured that all of the regular maintenance is always done on time.

What this light does NOT do however is signal that there is anything immanently wrong with your car. It is not a "Check Engine" light (that's the one you should worry about if it ever comes on), but merely a reminder for you to do preventative maintenance. That doesn't mean you should *ignore* it, per se, as you want to make sure you have your car on some kind of maintenance schedule, even if yours is not as strict as Honda's. But there is no need to panic.

It means you need to get your oil changed, or they didn't reset it after your last oil change.

it comes on after a certain amount of miles
look it over check all belts hoses brakes fluids
and check the timing belt if all looks good put your key in the slot next to orange light and it will goto green again if you don't reset it will goto red in a few miles but it is not the check eng. light just a reminder

go to autozone they will scan it no charge and do reset, give u possible causes and repairs, are u sure its not the oil change interval light,your owners manuel will tell u how to reset if thats the case
