Way dont work on citroen c5 2.2hdi 2004?
DB is v7.02, lexia is cheenese clon

[mattydr67]

You firmware is higher for the DB v7.02
Upgrade your Diagbos to v7.57 and it will works
Or downgrade your tool firmware to fw4.2.2 using PSA Interface Checker and then try to test the car again.
Also I belive your tool is already flashed
Good luck

Does telecoding works on 7.76?

@mishja,
You are saying "Yes, is flashed", what is flashed and to what version, also did it work or not? this could be helpful to others, it also assures"mattydr67" of his proposed solution.
Please be clear in your message.

@barbo,
Yes Diagbox from v7.66 and above, does Telecoding, but there are reports that there are issues with Peugeot 208. It would be helpful if you try it on your car and report back.

Flashed means that his tool has the not blacklisted serial ( C )
Flashed by one of the all known methods. ( flashed with external programners or by Mr. NLC solution )
Good luck

Upgrade to DB v7.57,still no working of all modules on C5 2.2hdi, work engine,front ligths, ABS, suspension, gear box


my English and spelling is bad, sorry for short posts
interface is flashed with mr. NLC solutions (vci updater),interface serial number is 921815 c (it was b, it seems to me is blacklisted), whether there is a solution for this interface with external programmers or better with mr. NLC method, or not solution at all. helping a friend who has 56 years and does not know a word of English. it possible to change any way the serial number, i change MAJ_ACTUAL to MAJ_FALSE but again the same situation.

[mattydr67]

Mate if your tool is flashed with Mr. NLC then you don't need to change the serial
I told you. You have two options
1. Downgrade the firmware at fw4.2.2 using PSA interface Checker and then use the DB version v7.02 that you have it alrwady installed
2. Upgrade the DB at version v7.57 and use the tool as it is
Good luck

I upgraded DB to v7.57 end is the same, so that is that, doing what he's doing. maybe some possibilities of modifications will help? thanks

@mishja,
1- Can you check if your board has the 10k resistor marked on the board missing or present? (see attached photos 1 & 2).

2- Is your device a "Full Chip" or some chips are missing? (Example photo 3)

I assume if it was flashed from B to C on board, then it has the Optocouplers.

Also, are you putting the correct RPO code for your car?
