Default Comfort Control Module

Hello,

I am looking for any tips on replacing the comfort control module in my 2001 Jetta. I have the Chilton manual (no help) and have looked all over in forums to no avail.

I have found a replacement CCM at 800vwparts for $100 - but I hate to get into this without knowing what I am getting into.

Any tips on removing the panels below the steering wheel?
Will I need to reprogram my keys? (And will it be drivable until then?)
Do I have to disconnect the battery first?

Thanks,
Jeremy

Thanks -

I had seen that thread (my post was the last post on it). I think I found the unit (hitting the remote unlock over and over and followed the clicking.) And wrote down the p/n (I think). IMO ... 1JM 990 799 ... 0270 3IQ.

I am going to order the part. My main remaining questions were what that thread left open - how to reprogram the keys (and will it be drivable until I get that done), and do I have to unplug the battery (or anything else) when I swap the CCM. These may be dumb questions - but oh well!

I will try to take some good pics as I do it and post a followup with the details.
(And messing around under there makes me think I should install an in-dash ipod and radar detector... hmmm ... one thing at a time).

Thanks,
Jeremy

The Comfort module has nothing to do with the Immobiizer system on your car, so it will be driveable. The Remote keys will have to be reprogrammed, which most times requires a VAG-Com to perform, though the 2 key method is an option as well. In my experience though, most times the 2 key method doesn't work, and you have to clear the learned values out of the module with the VAG-Com and program them that way.

You don't have to disconnect the battery. To reprogram the keys with a VAG-Com, go to address word 46, function 10, channel 0. This will delete the learned values stored in the control module. After deleting the learned values, go to Function 10, channel 1, and enter the amount of keys you want to program. After saving that value, push the same button on all remotes one at a time until you hear the horn beep, which confirms the remote has been stored in the system.
