Hmm, still must write that page about the frame format - hey on with the data anyway!
Well these are the idents I've heard about along with some more I found on my bus. Decodes I know about are on the way!
| IDEN | Data | Decoded | Certainty | R/W | Notes |
| 464 | ? | 0% | W | On the bus regularly without engine running (all 0x00) | |
| 4D4 | Audio settings? | 0% | R | I've not seen this (but I have no HU installed) | |
| 4DC | AirCon? | 0% | Looks likley | W | AC/Auto/Demist cabin temp... |
| 4EC | CDC info? | Partial | Untested | R | I've not seen this (but I have no CDC connected - see 4D4) |
| 4FC | Lights status | Partial | Looks ok | W | headlight, foglight, indicator state |
| 524 | Car status 2 | Partial | Looks ok | W | handbrake, left stalk btn, seatbelt warning, door lock, doors open, auto lights/wipers |

| 664 | Dashboard buttons | Partial | Looks ok | W | hazard lights, lock doors and brightness. |
| 6CE | ? | 0% | R | ASCII chars House Number and Street set for navigation (start&end 0x89) also memory lookup | |
| 74E | ? | 0% | Guess | R | Appeared after using remote to access sat-nav - nav instruction?(start&end 0x81) |
| 7CE | ? | 0% | R | On the bus regularly without engine running(start&end 0x87) (like satnav stuff) | |
| 824 | Dash speed & RPM | Partial | Look ok | W | rpm, mph and sequence number (presumably because of needle display?) |
| 8A4 | Dashboard gauges | Partial | Looks ok | W | hbeat, brightness, contact? engine?, economy(mode?) temp oil, water & ext oil+fuel |

| E24 | VIN | 100% | Total | W | 18 ASCII characters matches Vehicle Identification Number |
At present I don't have the standard head unit in the car so I will not be seeing messages from that and I won't be seeing any CDC messages as it is only on the VAN bus via the pass through in the standard head unit. So far this is data gathered from a bus log (VIN removed) taken with the engine off but the key in the ignition position.
Each IDEN is a hyperlink going to the single HTML page with what I know so far. It's ugly but functional!
