Thanks! Looks like the interface is not even identified as HEX-V2 by the (cracked) software - obviously they didn't bother to tweak that. Looks like the clone most likely was a copy of old hardware.




The above from:

No more USB Hex-cam? (or is this just news to me?) Also VCDS-lite question.

Was looking to get a hex-usb+can cable as used ones are about the same price and I couldn't find it on the Ross Tech website. It's obsolete and no longer available. Cheapest is now the Hex-Net for $449. :( For now I'll rent one from fixmyvw. (I have an overboost/limp problem on the freeway I...

Thanks @mmi
That goes a long way to explaining why I can’t code the engine module, but not so much why it has stopped working all together.
I’ve relented. Genuine one on way

 

[huw169]

Just to add. If I still can’t code the engine module I will be steaming mad!!!

 

[huw169]

Gendan don’t piss about. Cable arrived today.

On first scan I got a bit concerned as engine module still had Readiness N/A listed whereas the others didn’t. Just like early cloned scans.

Tried to bypass the long code tool as it still had the drop down menu for byte 5, bit 5&6, so went into Lcode2 as it gives all individual bits. Got to byte 4 and had a message come up advising my to abort. Will post more when I try it again.

Fortunately I’d tried it so many times before, I knew what the Hex code should of been so just did it there.

It took the code first go and CCS all works fine

Obviously it's time to get full snapshot of the van...

VCDS -> Applications -> Controller Channel Map ->

Tick the boxes as above and hit Go

VCDS Flashes screens for a moment (when finished hit "Done, Go Back") and in folder C:\Ross-Tech\VCDS\Logs\.... there will be quite a few files:
adpmap-XX-xxxxxxx....CSV and blockmap-XX-xxxxxxx....CSV

Better to have engine running, or charger connected - just to be sure not to flatten the battery.

@mmi
Thanks, I’ll give that a go and see what it tells me. I bet that spits out a ton of data.

 

[huw169]

@mmi
That’s loads of data!
Got to pop out now, but any pointers on where I should look first and what I might find interesting?
Thanks

 

[mmi]

There's even more - under each control module there is a button "Advanced ID"... to keep eye on if they have updated module software while servicing your van.

where I should look first and what I might find interesting?

Hmmm... it depends... A lot of events are counted in ECU - number of start-ups: manual, automatic, fuel counters, DPF soot and ash build up counters, etc. (file blockmap).

Modifiable parameters are found in the adpmap -file (subset of them also shown under VCDS adaptations). A word of warning here - when you stumble across selection "Reset all adaptations" in the VCDS - do NOT do that as it clears the settings of the module in question and it's not always easy to restore them. As a backup you could do the Raw HEX backup of adaptations - mentioned in my previous post (on screen snapshot).

Then there is another world by recording things (Advanced Meas. Values) while driving - word of warning here: it might be addictive... at least for some of us...
