If you are thinking of replacing your faulty CCC unit with another one, you should ask yourself why you should pay more for the same service. In fact, all CCC navigation units currently for sale are refurbished CCC units. Let’s destroy some myths first.Īll CCC faults can be repaired. We discuss what CCC repair methods to try or to avoid and whom to trust with repairing your head unit.
In this article we make the case that it’s cheaper to have your CCC repaired, provided you choose a professional service. This article is meant to help you make a choice. But deciding whether to buy another CCC or have it repaired and by whom can be a daunting task. Correctly diagnosing a faulty CCC may be tricky by itself. I recommend you check these first.If you’re dealing with a faulty iDrive CCC head unit, you probably don’t know what to do about it. The one you want is the one with about 5 connections on the top, but beware that as you pull it out of its slot there are also connections on the bottom. Remove the top, which I seem to remember is 4 or 5 fasteners, then inside there are 3 control modules. Take that out, under that is a plastic box.
That is the pod right below the windshield. The module is hidden in the engine compartment on the passenger side under the cabin air filter housing.
It does sound like you need to look here first. I got one as my car is 8 years old (650 convertible) and I still have an issue that I thought this may solve (hesitation / jerking when accelerating hard from a start). A brand new module from BMW cost me $130. There are a few YouTube videos out there detailing the fix. It has 11 fuses on it, as well as an issue with a particular solder joint inside on a relay that becomes a "dry joint". In the 645 and 650, as well as several other models, there is a power control module that affects everything from fuel injection to radio power.
