Exclamation CCC is dying! what can I do?

Hello everybody,

I have the well known CCC problem:
My CCC is in a "bootloop", it starts mostly on the first car start a day, but later on the second and further car starts it has a "bootloop". Sometimes after 5-40 minutes its getting bootet and working fine.
I have the problem since a month, sometimes its better, sometimes its worse.

I wanna start a thread here which hopefully will end in an HOW-TO thread for fixing the CCC.

What I did until now:

1. I read a thread in another forum where they reported that you can fix the CCC by replacing the capacitors form the power supply (from the CCC).
So I did, but nothing changed.

2. I also reseted the CCC with INPA, but also nothing changed.

Have you any ideas ? Where we/I can go on ?

Thanks in advance and

Greetings from Germany

Can't do much w/o data. Troubleshoot the unit - start with the power supply - verify power's within spec. How's she look?

Interesting you re-capped....electrolytic capacitors? Pic[s]?

Just looking at PCB's sometimes reveals a fault....look for toasted component[s].

Also, reseat connectors - oxidation's a b***h!

Ok, here is a pic of my power supply(sry didn't made more):[IMG][/IMG]

verify power's within spec -> Sry I have no specs... where can I get them?

In my eyes components didn't look toasted...

Whats PCB ?


Sry for bad english...

I think the interesting thing is, that once the CCC is booted it works fine for hours...
So the problem is connected to the boot process.
If its the power supply and considering that sometimes its working, I think I should disconnect the drives from the CCC maybe power is enough to boot every time --> Its the power supply.
But if it doesn't make a difference we should spend the power supply less attention.

Hmmmm....can's discolored - maybe heat/internal failure - and why is there a can? RF components?

3 toroids and honkin' big capacitors. Did you replace 'em all, identical parts spec? Equivalent Series Resistance is a good test for electrolytics.

Good question re: specs - don't have here - maybe a BMW coding forum.

Look for shiny residue on voltage regulators, diodes, and particularly circuit protection devices, due to release of 'magic smoke.' Come to think of it, might be a resettable fuse causing your issue due to recurring outta spec incoming power.

If all of this is like translating Greek, you need an electrical engineer to diagnose the unit, or someone with experience with circuit troubleshooting. Many Ham Radio operators are DIY engineers - could find a resource there. Luck!

Resetting with INPA does nothing. It's the same as resetting by holding the 2 eject buttons and the volume knob in. It's a soft reset.

Some people have had success in updating the software. You need an icom with a fiber optic connection to do this.

It's a risky process and people have bricked the whole system attempting it.

It's a very strict upgrade procedure. You must update modules on the most loop in a specific order. There are a few modules you must update and most can only be accessed with an icom head.

My ccc acts up in extreme temps. Really cold or hot and it freezes at boot. A soft reset always boots right up though

Hello everybody,

there are some bad news:

The ccc is getting worse and worse. Yesterday, when I started the car at midday the BMW logo appears shortly and disappeared instantly. Afterwards there were horizontal brush in the display, the ccc also didn't started yesterday.

Signs are bad. I give you updates as soon as possible.

Greetings

Hi Guy's,

I'm really disappointed about the BMW quality.
Since my last post the CCC didn't started at all and I use my car every day.
At ebay there are company's which advertise that they can fix every CCC for 150-200(206,94-275,92 US$) another thought was, that I can exchange my CCC with my local dealer for 750(1 034,7 US$).

But I don't want to give up, I try to get some information from the repair-company's , there must be ONE fault which causes these well known mistake.

I keep you up on date.

Greeting from germany

If you end up spending more than $1000 on this repair.....skip the CCC.

Look into a CIC retrofit. It's the newer HD based Nav system is much better than the CCC.

Parts and install will run you about $1200-$2500 depending on options but if you're going to spend the money at all, you might as well upgrade.

Just a warning. If you ever need to update modules in the car, you cannot do it at a dealer unless you get a CCC unit installed. The dealer can only program the entire car, not individual modules.

There are work arounds....like if you're familiar with WinKFP, you can flash and update the modules yourself.

But to do the CIC upgrade, you need to trick the car into thinking it had a later production date by modifying the VO. This will prevent a dealer update because the production date will be "wrong."
