History showing long coding changes I did not make

[exult]

Hi everyone, as the title says, I recently looked at my history and noticed quite a few long coding changes that I had not done myself. Is this normal behavior? Should I manually revert everything there I'm seeing? I'm specifically concerned about the engine module changes. Thanks in advance for the help!

^^^ Please don't take offense - but I seriously doubt that those code-string changes could be made to your car and the car still works!!

Even if there were genuine attempts to make these amendments, most of the changes are impossible because the amended values impose a very different Byte count on the modules.

While I'm sure that the crazy, zany software guys/gals @ VOLTAS IT do their best to ensure that these history reports are accurate - the veracity of the information is really dependent on when the snap-shot of values is taken. For example, for VCDS, the data for the equivalent reports is locked-in just before the user presses the "Doit!" button - which is the same as the green tick in OBD11. This means that the history reports in VCDS show what the user asked the module to change - the reports don't show what actually changed! I don't know when OBD11 takes the data snap-shot for these reports - it could be the same as VCDS - perhaps if anyone from VOLTAS IT is reading this. they might respond?

What were you doing to the car @ about 1722 hours on 2018-11-26 (i.e. about 6 months ago)?

I suggest that you make a scan report of the car. Then perhaps check the code-string values on the modules in the scan report with those in the history report.

Hey Don,



I appreciate your input. I thought the same thing...that likely the history was reporting wrong info. Today I looked at the individual history of each module, and the long coding changes are not shown there (actually I think the individual histories do not show all changes there to begin with).



As for what I did that day...I made the following change 4 minutes after those supposed Long Coding changes, nothing before that:



Adaptation

Control unit: 44 Steering Assistance

Name: Driving profile switchover

Values:

Old value: Incremental, controlled over time

New value: Direct, controlled over threshold value

Mileage: 5258 km

Date: 2018-11-26 17:31



I guess its possible either the application crashed mid scan, or I had issues with my phone, but besides that, nothing else was done that day.



I may be overthinking this, but can you elaborate on what you mean by "I suggest that you make a scan report of the car."?

Looks like something had a hissy fit, pretty sure your car would be going mental if you had that data on it

I sense that you agree with the general view of respondents here that the records in your first history file are absolute nonsense. Clearly the values can't be real - which suggests that somewhere, somehow there has been what seriously technical experts describe as a "glitch".

Because yours is the first that we have seen of this problem, whatever caused the odd results is not systemic to OBD11 dongles. We could analyze the problem and in the process, also contemplate the meaning of life (which isn't 42) but it just ain't worth the effort - I reckon!!

So, without intending any offense - yes, I suspect that there are other things in life that would be better served by your attention !

But, if you want to persevere  (simply as an academic exercise) - the answer to your second question is to push the big button in the screenshot below (which is taken from now obsolete software, but it's the same in the latest version of OBD11). After the scan is completed, press the smaller blue button on the lower RHS of the picture and one-by-one check the code string on each module against the records in your first post above - but I think that we both know what the results of the comparison will be.

Yeah definitely. I work in IT so I completely understand that this stuff can happen. I will do a scan and check quickly when I have some time but I am not worried about it. Like you guys said, I agree that had those changes had actually been made, I would've experienced some issues. But still, I figured I'd ask to begin with just to make sure. 

Thanks again for you guys' input!
