Swapping A4 B8 Convenience module - tips/tricks?
I'm about to help a friend of mine swap the Central Convenience Module (8K0907064N) on his 2009 A4 Avant.
He has a raft of errors showing up when I scan with VCDS, corresponding to a selection of "real" problems with his car. The CCM seems to be the main culprit (long-standing EEPROM error among others) and potentially is implicated in others. He's ordered a used replacement of the same N version and I plan to check the coding and replicate using the Ross-Tech reference: http://wiki.ross-tech.com/wiki/index...Comfort_System Edit: Sorry, here: http://wiki.ross-tech.com/wiki/index...(8K/8T)_Tweaks Is anyone aware of any relevant tricks or tips to help with this; the unit seems to be located quite accessibly behind a removable panel in the offside boot area? Are there any component protection issues for example? |
That platform has two BCM's, and you missed a number off the part so not sure which module you mean?
Either Address 09: Cent. Elect. (J519) 8K0907063N or Address 46: Central Conv. (J393) 8K0907064N - But I think this is the one due to your description of its location. Just note down the current coding and perform a Controller Channel Map of the current module prior to removing it. If you need security access try 16017. Not sure about CP on that platform. I would note this caution from Ross-Tech Quote:

Thanks for the other advice too, every little helps. +++ And by the way, I don't think this vehicle has keyless entry, it's press buttons. The key fob has to be inserted in a slot in the dash to start. |

It's not so much to do with KESSY, more that the immo is onboard 8K0907064N.

Does seem a bit odd though given it's location remote from the key/cluster. :Confused: |
