View Full Version : Car won't respond

11-04-2014, 03:45 PM
My A6 this morning did not respond to the start/stop button and after attempting to use the key, the key locked in the ignition. There is no response to turning the key (no dash lights, accessory mode, etc.). It just turns back and forth without releasing. Some other electronics in the car work fine (door locks, MMI turns on with volume button, etc.) but no response whatsoever with the key. I managed to get the key out using the little release button, but no change in the car's behavior. It won't respond to any of the buttons on the key when pressed.

Below are the results of a VCDS Auto Scan:

Looks like the EZS/Kessy/Steering lock (05-Acc/Start Auth) under the steering column is not recognizing the key/transponder. This can be a key/transponder issue or an issue with the EZS Kessy itself (corrupt eeprom/flash). Do you have another key to try? Battery voltage ok?

If it wont respond call it back.

You sir have added some much needed humor to this situation.

I have tried my other key to no avail. The car battery is full (I can access that section of the MMI).

Would there be any benefit to clearing the codes at all?

Access control module failure is what it sounds like, I had this problem at the beginning of the year. Had to have it towed to the dealership and they had to replace the steering column, it was a bit of a hit financially but there wasn't a way around it from the research I did on it. Hopefully it's not that but from the sound of it you will need to have the steering column replaced.

Sounds like steering column- pretty common now unfortunately and yes it's gotta be the dealer most likely ...

Control Unit for Access and Start Auth (also referred to as J518 or EZS/Kessy) failure. Faulty component in the system board, broken microswitch or corrupted flash in the Motorola MCU . Dealer or can also be repaired using a donor unit from salvage yard... via eeprom/flash cloning. The unit is essentially part of the steering column, but can be separated and removed.

Good luck with that, there was 1 thread here I found in which the guy did that and it cost almost as much as just replacing the whole steering column plus all the time it took for him to do it. If I'm not mistaken when done he said it wasn't worth it. Now you are probably correct that you could find the steering column in a wrecked car and swap it out and it would be cheaper but that probably isn't so easy either to find and have the dealer or other mechanic swap them. Then when the swap is done you still have to code the keys to the new column, it's a lot of work.

Plug n play if EEPROM is cloned. EEPROM contains all needed info (specifically: VIN, PIN, Component Security Bytes, MAC address, Power Class and all Key coding). Or adaptation of second hand unit via OBD2 with special tools (and I don't mean VCDS). Not sure what a new J518 runs, but if new unit from dealer it does get coded via Geko online access - Germany, which is obviously extra $. The unit is a brain of the immo system.

Definitely not a dealer only job.
