Well the gauges are working more frequently now.

I twisted the twin gauge pod in a clockwise direction and they started working again.

LED Displays are lit up but the Tach/Speedo work only after 930 AM....

Next will be the hammer

Did you ever figure out what is going on?

i have a 2005 R53 that the speedo and tachometer freeze when accelerating past 5500rpm.
Most of the warning lights come on also and I lose power steering. Everything comes back when rpms drop. It takes a few seconds for power steering to come back.

Any ideas?!

I agree, sounds like the alternator going out.

I wonder it could be the belt slipping or harmonic pulley starting to fail?

My issue is still intermittent;[FONT=Times New Roman][SIZE=3] ev[/SIZE][/FONT]ery week or so I give a gauge cluster a twist when they stop working and all is fine for a while.
