S80 info display dead
 

Hello,
i've S80 T6 2000 with 2.8 twin turbo.
The display doesn't show information and warning messages.
I think there should be open-door indicator but it's also invisible...
Is there a specific fuse I need to check again? Illumination dead? Allthougt all fuses checked multiple times.
Please, advice from what to start searching?

Also, cruise control doesn't work. Maybe there's connections between these 2. It just shows CRUISE in dash when turning it on, but that's all.

Update. Seller had removed illumination behind the dash. Crap. Ay least, this is solved.
Got the srs-airbag service urgent.

That is why bulbs were removed.
You need to get error codes using dealer's computer. Sometimes it can be
just removing socket when ignition is on in this case clearing the errors will do the trick. But if errors are Red (means there is a real issue) that does not help.

^^ that fault is because of someone have changed front seats from half-leather heated electronically operated to full leather heated. They have different connectors and safety belts aren't connected to the car. Got the half-leather interior that needs to be redone.

Yesterday once again one number plate light blow out. Wish me luck finding the reason why it's out again. :) That's why I got "Bulb failure position light" error.

Now I need to replace front left ABS sensor, both right side lambda probes. And I haven't even looked under the car. Paid 30$ for Bosch diagnostics.

Got the cruise working but it works until dash light up error for ABS/STC -> triangle with sliding car icon. :D

Resoldered ABS/STC ECU connector pins and 3 problems now gone:
- abs error gone
- stc error gone
- cruise works.

One error about airbag remains. :)

Those fault codes are back. So, this time need to find unopened working ecu :D fcuk s80.

looks like you did not do research on the S80 before buying. otherwise you would have known the problem older S80 face.
or maybe you are rich and can afford hefty repairs

I'm not owner, I'm person who's doing repairs.
Resoldering ecu took about 1h including taking it off and putting back. 10usd maybe...
