One of the favourites ... a faulty idrive on BMW 530D E60

[Hammerant]

The screen flashes the grey screen with the BMW logo. It cycles on off at a lazy interval.

I tried the three finger reset. No result. 

I could hand the car over to an audio/electrical  specialist who would fit a salvaged unit of unknown condition/age for around £400.... but

what is the sensible process of diagnosis ?  eg could it be one of the fuses ? what next ?

The fact that the screen lights up with the logo suggests, it is not dead, but how not dead is it ? is it barely alive or alive but needs a tweak?

I am dying to know and would be really grateful for any advice

Welcome to the Forum

Check www.realoem.com put the last 7 digits of your Vin into the search box it will call up your model then if buying parts you will know what will fit.

You could contact specialist repairers such as Cartronix, or ECU Testing or BBA Reman then if it's  repaired (1) You know it will fit and (2) It will have a Warranty

From experience the I-drive controller was an early culprit as was the CCC unit, yes check all the fuses and Connectors (unplug spray with a good contact cleaner and re-make the connections) 

I have had 2 CCC units repaired/upgraded by Cartronix for friends of our sons and replaced 6 or 7 I-drive controllers. Normally a Diagnostic Scan with BMW INPA/ISTA or BMW 1.4.0 will point you at the right solution

Hope this helps
