Is it only possible to erase codes 50 times with the lexia??

[CitroSwede]

Hi everyone.
I have searched in the forum, but i didn't find a topic about this.
I have for the first time tried my china-lexia on a C5, i helped a friend to erase some codes on his C5 HDI.
But after every time i erased an engine related fault code, the lexia said that i had 50 (or was it 25?) possibilities left to erase a code.
And for every code i erased, the times remaining went down.
It also said something about a "sales region" or something like that.
This message was only shown after i had erased an engine related code.
This counter was only visible when i erased codes on the C5. It says nothing about this when i'm erasing codes on my xantia...

Does anybody know what it means?
Does it mean that i only have this amount of times i can erase codes on that specific car, or does it mean that the lexia itself locks up when i have erased the maximum number of codes?
Or... is it just a false warning, nothing happens when the counter reaches zero?

I have the usual lexia-clone, the same as everyone else i suppose.
Does anybody have a clue what this means?

Anyone

I know DickieG and I have discussed this in the past but never formed any positive conclusion..

We believe (hope) that after 50 the counter rolls over to zero but we've never proved it...

In the 'Sales' bit you're supposed to record the mileage (kilometerage?) when the reset took place...

I have searched on many different places on the net, but nobody seems to have erased more than 50 times.
But... i suppose that everything is stored in the software on the computer, not in the interface itself.
So if it locks up after 50 times, it should work again if the lexia software is uninstalled and installed again. I hope..
When i erased the C5-codes, i didn't write any mileage at all when the reset took place. It seemed to work anyway.

Well, for once i was lucky when i did a web search and i found some info about this on another forum.
So i quote the text here, so other members will see it too.

"the 50 times error erase, means if you reach this you will still be able to continue"
" 50 only means it will only store 50 logs, so if you erase faults 51 times, it will start over writing stored logs!

Sounds good. I would be surprised if a lexia-clone had some sort of built-in limit.
If that were the case, then would many people have been VERY loud on the net forums.

I have seen a car with more than 50 codes erased, it was a C8 (no surprises there )
The diagnostic session just fails to tell you how many previous codes have been cleared.I was led to believe the Ecu would shut down at this point, but I can assure you this does not happen

Excellent Thanks for that Lighty. 50 is a lot. Rattiva in all her 204000 miles has only had her engine ECU looked at four times (or is that 54 time or 104 times?)...

No because after 50 it doesn't tell you any number, so your little gem has been well behaved

Or neglected

I did a C6 last week that had 326 faults mostly because to multifunction screen wasn't working due to a faulty RT4...... but that's another story.

The fault storage capacity is down to the design of the ECU.
40 or 50 codes max before overwriting was common in ECU's designed in the early 1990's.
Modern designs of ECU have much larger fault storage capacity.
I would not be surprised if the earlier versions of the Lexia programme had similar fault capacity limitations built into the software.
Software designers do not waste time testing a programme beyond its actual needs.
They have enough trouble getting it to work correctly after a fashion within the required limits.

The 50 limit and milage recorder is only on the injector menu though, you can erase all other faults without having to impact on this limit.

Though yes, its not really a limit ...

Donning one's professional hat for a moment, amen to that brother!!!

Sounds like the business policy of BL in the 1970's
