Faults 00003 00447 00532 Display Cluster & Fan Display Not Working

[Badadd]

Hi everyone - we have a 58 plate A3 8P 2.0 diesel with some strange faults that have left us (and the garage) scratching our heads. There is a background story as to why the garage had the car in the first place, which was related to ABS, which is now fixed. I can elaborate further if needed. These problems seem to have started since then and at this stage, we presume unrelated.

3 faults currently found:
00003 - control module
00447 - function limitation due to over-voltage
00532 - supply voltage b+
Screenshots of VCDS errors attached

Digital display on the instrument cluster and the fans has stopped working.

We were getting a low voltage from the battery, which was old, so changed it after the above happened, this did not fix the issues.

Can anyone help us? Thank you.

Which control module is that logged under?

Just asked the garage, they said "instruments (measuinrg block 17)" - does that help? Thank you

Sounds like the clocks, aka instruments are ********.

 

[Badadd]

oh dear - that doesnt sound good. Would the fan display stop working at the same time too though?

Surely your garage can figure what's going on, but cluster can cause number of things to not work, but I'm not aware of the car situation so I'm just talking from experience.

I have the exact same issue (same codes, same make/model but a 2009) did you find a solution?

Put the key in the ignition this morning to find the dashboard & the A/C display have issues:
Dashboard bulbs work (handbrake etc.) but none of the dials or dashboard displays work.
The A/C functions as normal but the display doesn't work.
(everything worked fine yesterday).

Tested the battery & alternator, checked cockpit fuses & main fuse box (no issues), scanned with VCDS, results below:
