Title: WANTED: RB4 encrypted/decrypted dumps (Audi)! Post by: niston on January 04, 2018, 03:35:18 PM I try to learn more about the BOSCH RB4 clusters from Audi A4 B6/8H7, so I'm looking for both ENCRYPTED and DECRYPTED dumps of your clusters!
If you have any, please post both encrypted and decrypted, for the same cluster. I shall be grateful if ultimately something comes out of it ;) Please also include some background info on the IC if you can. Like: Mileage, IMMO 3 or 4, diesel or gasoline and ideally also engine code, if it has def/error or anything, ... TIA niston Title: Re: WANTED: RB4 encrypted/decrypted dumps (Audi)!

RB4 D22 Cluster PIN Offsets (decrypted): 0x0126, 0x0127 - Little Endian Upload more dumps (need both encrypted and decrypted!) for more discoveries. ;) Title: Re: WANTED: RB4 encrypted/decrypted dumps (Audi)!

Title: Re: WANTED: RB4 encrypted/decrypted dumps (Audi)! Post by: niston on February 09, 2018, 03:17:32 PM Did you take dump of NEC microcontroller? Is it possible? I know of someone in Germany who wrote a patch for the dreaded DEF Error, so I suppose it's possible. Perhaps there's a JTAG port somewhere, but I haven't looked into it yet. I should be holding another cluster in my dirty hands pretty soon, so there'll be another crypted/decrypted dump on my part. Not much of a response (as in posted dump pairs) I'm getting here tho, eh? |
