please can any one help with my (brake light bulb ) failure warning light constantly lit on cluster, but no warning sound. my car is a4 b5 1999 saloon.

 

Just replace both bulbs with new ones,normally happens when a buld is on its way out due to a difference in resistance of the two bulbs. Resistances should be the same on both bulbs for the vehicle computer to ok it.

hi thanks for reply ive replaced both bulbs from audi and all bulbs work but warning light for brake light stays lit but no warning sound could it be the relay 387 bulb monitor box its been on for months hope you have any idea thanks.
