Ccc modules can be repaired by lau!

I am finally getting round to sending my ccu to LAU. Can anyone tell me what functions i will lose without the ccu connected and would the car still be driveable?

No, you can't. When you use the lock on the driver's door, you physically control the lock in the driver's door, meaning that door can be locked. However, the door lock sends a signal to the driver's door control module that in turn puts the 'lock' command onto the convenience CAN. Without the CCCU in place, that signal can't reach its desired destinations, namely the other door locks.

Without the CCCU, your car won't lock, you'll not have an alarm, you'll not be able to put the windows down, the interior lights won't work as they should and things like the fuel filler release button may also not work, though that problem is easily overcome.

Cheers,

Tom

What version of CCCU have you got? With a 51-plate TDI, I imagine you'll have a Q unit. If you can confirm your version, I may be able to help here...

Someone correct me if i'm wrong but if you lock your car with the drivers door open using the central locking button on the inside of the drivers door then lean over and disconnect the plugs from the CCU i believe that all the other doors and boot will remain locked but you will be able to unlock and lock your drivers door with the key manually, so your car will be usable and be able to be left securely.

Only down side as i see, is that you won't be able to carry passengers as you won't be able to unlock anything else.

This is true! If everything other than the driver's door is locked at the point when you disconnect the CCCU, then you'll be able to continue using the car with just the one door.
 
Hello,

Maybe im too late, but some experience from me.

I was driving A2 for few months without CCU. What doesn't work: el. windows, interior lights, central lock, boot lock and fuel cap. Also, no parking brake lamp :)
How to overcome these problems. If your CCU is still a little alive, connect it, use central lock to lock rear doors. Disconnecting CCU will leave rear doors locked and both front will be lockable by key.
If you want to refuel , open your boot by using emergency "hatch" , then remove right side plastic cover for lamp inside boot, and push down the "cylinder" to open fuel cap.
I sent my unit for repair to Lau month ago, he received it in 3 days, sent back another day. Tho, received it after 20 days, but it's because Lau sent it on Christmas, so long delay from German post :)

Hope it helps.

Thanks very much for the additional info, as this answers a question that I had about how the convenience CAN system operates.
It follows that...

When the driver's door control module puts the 'lock' command onto the convenience CAN, the other door control modules clearly act on that directly, with no routing via the CCCU. So, if you've got a car with rear electric windows (and therefore 4 door control modules), all 4 doors can be locked and unlocked without the CCCU in place. Only the boot remains a pain.
However, in cars with manual rear windows, I know that the CCCU acts as the door control module for the rear doors. Therefore, if you've not got electric rear windows, the rear doors cannot be locked or unlocked without the CCCU in place.

Cheers,

Tom
 
Rear doors with manual windows can be locked ONCE. If you remove CCU after locking, you will not open them from outside, only from inside. If you open from inside, they will remain unlocked and will not lock again without CCU.
Boot is always openable manually, but I agree with pain on unlocking :)
 
Just a quick update. The car will remain secure if you remove your ccu. I opened drivers door and while open, engaged the deadlock from switch inside door. then leant over and disconnected the ccu. once done, i closed the drivers door and locked from outside. All doors and boot remained locked and alarm functioned..:)
 
Just received my ccu back from lau.. should it just be plug and play and everything will work, or do i need to get get the key re-programmed? before i sent it to lau i was having probs with windows and c/locking. fitted it today and windows are fine but central locking still not working from key fob..
 
You can just plug it in and everything should work... except the remote keys. They'll need to be rematched to the CCCU.
