Hey guys,

i have a problem with my warning and clock unit.. the washer water level bulp is glowing all the time, while driving and the ignition is ON.. the tank is full.
in addition, none of the warning lights light up if i turn the key to ignition ON
they only light up, if i use them! ie open the door, parking brake etc.

ok.. i thought my warning unit is bad, so i baught one from a 91convertible which was working fine, and i noticed the same problem as before..

oh please help! im going to go mad, i dont want to go the idiot way and take out the bulp

thx in advance

Could be a stuck level switch in the washer bottle. Pull it out and check it. There's info in the FSM Body Electrical chapter if you need it.

but i dont think its only the washer sensor.. because the lamps dont light up if ignition is ON.

No, the washer light is a problem in itself.

All the lights coming on when the key is just put to ON, is a seperate problem alltogether.

That is an Alternator or alternator relay in the CPU problem if it's a series four car. IF a series four car, all you have to do is pull the small plug off the alternator. Turn the key to ON. Put a ground on the white/black wire and all the lights on the idiot display should come on. If not, then either the alt relay in the CPU is kaput or there is an open in the wiring b/t the alt and the idiot light panel. It could also be a blown fuse to the CPU alt relay but doubtful.

So, if a series four car, do the above. Make sure you don't put the other wire to gnd. IT's the WHITE/BLACK wire, NOT the BLACK/white wire. IF you confuse the two the worst thing to happen is a blown fuse.

To fix the washer problem, remove the washer bottle and figure how to free up the low switch inside the plastic bottle.

The four socket connector to the washer bottle is inside the engine bay about six inches from where the neck of the bottle enters the right fender area. It's black in color. To disable the light, you could extract the green wire from the four wire, black connector.

its a S5 car, so what is difference to the S4 one?

there is a plug with 2 wires, one of them is white/black, i have grounded it, but nothing happend, no relay clicking, no lights coming up. i dont know well how to use electronic tools. i used the option to look for an open. i grounded the white/black wire, and the volt/ohmmeter has shown me an open.

hope u understand what im talking about, im sorry for that.

HAILERS

I was talking series four. BUT, the series five has the same wires and connector. Four wires. One GREEN, one BLUE, one BLACK and one blue with a green stripe.

If you found a two wire plug in that area, I'd say it's the side light plug. Be not shorting that sucker with the light on.

Find the four socket plug with those wire colors described above. Unplug it. The amber light WILL go out.

the all idiot light problem is bad solder points in the cpu in the driver's side kick pannel, take it ouf and resolder the pins,

HAILERS

Sorry, but that's not right. If the author of this thread will disconnect that four wire plug in the right side of the engine bay the light WILL go out. It will go out because the circuit iwll now be open. It's just a switch in the bottle that is frozen together making a circuit. It is NOT a cluster problem.

ok so i have unmounted my IC, and looked for a plug with 4 wires.. found none! only a grey plug at the top of the alternator with 2 wires to it. unplugged it, plugged back on again.. and now it is working lmao.. all lights come up if ignition is at ON. i am glad it wasnt more to work on

thank you all and specially HAILERS

Awesome info HAILERS, I love seeing someone tell how to actually diagnose a problem and not just take stabs at what might be the problem. Quality posts

HAILERS

I guess I wasn't clear on where the four wire socket is for the washer. It's under the airfilter afm. Remove that item. On my car, S4, there are two plugs going into the right fender. One is a two wire affair for the side light. The other is a four wire plug to the washer motor. Disconnect that plug. The light for the WASHER will now be out once the car is up and running and the alt is putting out.

I KNOW this from personal expierience. My WASHER light is on all the time for about a month and the fluid reservoir is FULL. I knew what it was and I ain't a gonna fix it. It's too much trouble for no gain. So when I saw your post, I disconnected the plug and the light went out, to confirm what I had wrote on this site. I plugged it back in. The light does not bother me at all and the washer works.

Glad you found your alt plug and reconnected it so all the lights will come on when the key is first put to ON.

while i was changing the warninglight units, i have just pulled out the bulp for the washer sensor.. so my washermotor works fine, the light isnt important at all.

but somehow, i am experiancing a brakelight problem. i have 2 warninglight units here. the first is one which was in my car, and the second which i purchased from a convertible (its the same as the S5 here in germany (200hp turboII))
so i used the one from the convertible, and noticed that there was no ABS lamp in there. I put in a bulb, bu nothing happened.. i think its a unit for a nonABS version? all the other light came up very well.
well, i tried and installed my old unit again. all lights are working fine, abslight too. but the brakelight isnt coming up while ignition at ON. only if i pull the handbrake?? do not understand this.

or am i that stupid,that i didnt notice my handbrake was tighten while i tried it with the convert. unit? lmao
