The oil light on your dashboard doesn`t always mean your oil is low, leaking, or dirty. Instead, it might mean that your oil pressure sensor or your oil pump needs to be replaced.
If you drive an Audi luxury vehicle, you should have your filter and oil changed every 10,000 miles or 12 months, whichever comes first. However, many vehicles need oil changes every 5,000 miles or 6 months.
If your warning light turns on, you have low oil pressure, and that probably means you need a top-up. When there isn`t enough oil, a sensor picks up the deficit and lets you know. Even if the oil warning light only flickers, you need to have things checked.
Oil pressure drops can be caused by a clogged filter or a serious oil leak, although leaks don`t usually just happen spontaneously. No matter the cause, if our oil pressure gauge heads downward quickly, do the above. Pull over and call for a tow to an auto shop. Don`t keep driving your vehicle.
Audi continuously work along-side Castrol to engineer engine oil to maximize performance and reduce fuel consumption and so recommend using Castrol EDGE Professional LongLife III 5W-30 engine oil for your Audi car.

As you may know, these lights are designed to come on at specific mileage intervals that are preset by the factory. When your mileage exceeds a certain amount relative to the last oil change, this will trigger the lights to come on. Typically this will include the oil light and the check engine light as there are also other basic service items that are checked during oil changes. I would recommend obtaining an owner’s manual for your car if you do not already have one. This will usually indicate the specific service intervals and recommended maintenance items for your vehicle at the various mileage intervals.
The tire pressure monitor will also come on when the air pressure in the tires has reached a specific threshold relative to the tire design specification. Tire pressure is also impacted by the outside air temperature. For every 10° drop in air temperature outside your tires will lose about 1% in PSI or inflation. As you may know, as the temperature of the air changes the density of the air changes as well causing the tire pressure to be impacted by this. When this happens, the sensors in the wheels will detect this change in tire pressure and cause the tire pressure light to come on. Aside from replacing faulty tire pressure sensors, another way to help prevent this type of fluctuation in tire pressure is by the use of Nitrogen in your tires rather than regular air. As you may know, air is approximately 78% Nitrogen, 21% Oxygen and the rest is water vapor and some other small concentrations of gases. Nitrogen is much less likely to migrate through tire rubber than oxygen. This will maintain your tire pressure much more consistently during large temperature fluctuations.
If you’d like, a YourMechanic certified mechanic can come to your home or place of business to inspect the vehicle and perform an oil pressure light is on inspection to diagnose the vehicle and suggest potential repairs.
