Instrument cluster fault????

[pdf11]

Hi all. Having problems with my 2001 a6 2.5tdi Quattro sport. It started blowing fuse number 15 which from what I can tell power voltage meter and clock memory. I've checked the battery, everything reads as it should. The VAG com code comes up with
Address 17: Instruments Labels: 4B0-920-xxx-17.lbl
Part No: 4B0 920 981 B
Component: C5-KOMBIINSTR. VDO D12
Coding: 00460
Shop #: WSC 00001
VCID: 25410EECBF9C8736C81-5140
WAUZZZ4BZ1N131982 AUZ7Z0A1787595
1 Fault Found:
00668 - Supply Voltage Terminal 30
53-00 - Supply Voltage Too Low
When I turn off the engine, the rev counter, temp and fuel gauge freeze, staying on the positions they were on. When I turn on the ignition, the said gauges an rev counter start flickering until they reset. The voltmeter takes its time to reach 14 v. On top of this, all red centre console lights don't work. Checked all fuses, all ok apart from number 15 which keeps blowing.
Any help would be greatly appreciated
cheers

Disconnect the clocks and try the fuse 15 again to rule them out. trace the wiring and any other equipment
on that fuse as well
