Urs6 trip computer blank?

[89 Coupe]

Today my trip computer went blank. I've had the car almost 2 years now and its never had a back light, not sure if they are meant to have one or not?
But the trip computer has stopped working all together. I checked the manual which I didn't really see anything helpful in there so I checked the fuses and they are all fine.
Also the auto check / warning light is not working either.

Any suggestions?

Hey, thanks for the info! very helpful, might jump into it tomorrow and have a look whats going on inside the dash cluster.

Hopefully it's a nice easy fix

It has started to work over the last two weeks but giving incorrect values or frozen on one value, flashing the cycle of warnings on first start up.
In the last week after buying the correct tools to take it apart haha it has returned to normal functions and I have replaced all 11 bulbs giving it a fresh look (about 4 were blown) and confirming that yes it does indeed have a back light which I am very pleased about.

Just for that dash alone I would own one of these cars!

Its a great looking cockpit and only 5 screws to take the trim and cluster out completely!

i think Audi have lost the plot with their more recent efforts in cabin interiors......these old ones seem to have a much more aesthetically pleasing, more cohesive layout

btw where did you buy the bulbs and how much? I got scared off the dealer years ago when they quoted about $7 a bulb. I've been scavenging them from spare clusters and pick a part ever since

Hi, I got them from Archibalds for $2.50 per bulb, the lads in parts department there are great to deal with.
