Hi,
I've just bought a 2008 E91 335d (pre-LCI).
The previous owner has had the CCC system upgraded to the CIC system, and I'm very impressed with how it works.
I think there are a couple of mods left to do:
1 - The previous owner mentioned they've not yet upgraded the controller to the CIC version - e.g. I have the one on the left.
On eBay these seem very cheap (£30). Is it plug and play? Do I need to do anything else to fit?
2 - Upgrade the maps to the latest version.
3 - Potentially replace the HDD with an SSD.
Apologies if this has been covered before - I've done stuff with ICE before, and done BMW "coding" (NCSExpert) on my E85 Z4 but all this iDrive stuff is new to me!
