Re: Replacing dash lights
You may be able to reach the bulbs from the back of the instrument panel, you will need to remove any lower panels that block access, if they can't be removed from the back then you will have to R&R the instrument cluster assy and any other unit that has defective bulbs, make sure you get the correct repacement bulbs, they may look the same but have diffwerent luminosity ratings, wrong bulb will be to dim or to bright and hot burning, this can damage the bulb socket, check your owners manual for more info.

The ignition coils on your Audi A4 are what provide the spark to the spark plugs, which sit underneath each coil. Every cylinder in your A4's engine has a spark plug and an ignition coil assigned to it. Sometimes, the ignition coils can fail and require replacement. Typical symptoms of a failed ignition coil include a flashing "Check engine" light, a rough idle or hesitant acceleration. Replacing the ignition coils on your A4 is a quick procedure that takes just a few minutes.
Park your Audi A4 on a level surface and open the hood.
Remove the plastic rivets that secure the plastic engine cover to your engine with the flathead screwdriver. Depending on your engine, there may be either three or four plastic rivets, which are all very obviously placed. Set the engine cover aside.
Firmly pull the ignition coil you need to replace up from the engine. Since it does attach to the spark plug, you will need to apply a little force. Be sure to pull directly up so that you do not bend the metal rods at the bottom of the ignition coil.
Unplug the ignition coil from its wiring harness. Depending on your engine, you may need to use a flathead screwdriver to pry up the loosening latch on the wiring harness.
Insert the replacement ignition coil into the spark plug cylinder and push directly down until you hear a slight popping noise, which will indicate that it has been installed correctly.
Replace the plastic engine cover and secure it with the flathead screwdriver and the plastic rivets to complete the procedure.
My 97 Rodeo had the same problem. No Tail lights, no. Dash lights. There is also an annoying buzzer that goes with the set telling you the lights are on, there is no key in the ignition and your door is open. (you don't notice it when it's gone but you sure notice it when it's back) The Fuse (taillight Illum) was good, The Light relay under the hood was good and all bulbs were good. What fixed this problem was replacing the tail light relay which is located in a panel just to the left of the brake pedal also called the kick panel.Inside there are 3 relays. I replaced the one in the middle and got everything to work. If you need to identify the relay you can put your hand over it and then turn the lights on and off. The correct relay should click. Mine was the middle one. Hope this helps someone because it stumped me for months.
it may be bad, i would replace that and see if the light comes back on,its easy to change ive done a few,just drain the oil then remove bolts and remove, install new gasket with new one,theres a way to bypass to test, i belive if you just unplug it or jump the wires,you can try both ways first before replacing it,if it has more than two wires going to it then dont try jumping it, just replace it, good luck.
The vehicle would seem to lose power as the transmission has gone into 'safe mode' and the transmission control module has detected a fault in the transmission hence the flashing gear display. you need to get someone in a dealer or someone that has the technology to plug into the car and find out what the problem in the trans is. hope this helps.
The most likely cause is a faulty oil pressure switch as there are up to 3 fitted get it checked ASAP could be low oil pressure!!
I take it this is the oil light flashing not "oil" in the dash insert ?
YOU HAVE 3 BUTTONS ON THE DASH (RIGHT HAND SIDE) YOU WILL HAVE ONE WITH A SPANNER (BUTTON A) AND ONE THAT HAS TWO 00 (BUTTON B).....HOLD A,SWITCH IGNITION ON,RELEASE A.PRESS B UNTIL DISPLAY CLEARS..MAY TAKE A FEW GOES BUT YOU WILL GET IT...
