My A4 has displayed some several random warning lights. The other day is was a red symbol of an oil can, yet the oil level is perfect. It didn't stay on long.
Today (during a heavy rain period) my wife had the chime and Brake warning symbol and an orange? Triangle flash up for a minute then go off.
There was another last week but due to negotiating a roundabout I didn't get chance to view the symbol clearly before it went out.
What would cause these random things?
The brake pads and brake fluid are all fine....
