I'm just back from my dealer who agreed to put in the VCDS codes for 3 items:

Cornering fog lights (STG09/BYTE12/BIT06

Tear Wipe (STG09/BYTE14/BIT04)

Coming Home Lights (STG09/BYTE10/BIT02)

None of them worked.

Just looking at a print-off he gave me, just above the Byte and Bit columns, there is a heading "008 - Coding (Service$22)"

I'm wondering if this means he was in STG08 and not STG09...

My car is a 75bhp manual green tech - were the codes for these 3 functions I found on the forum for the 60bhp or something...?

Any help you can give me to give my dealer would be appreciated!

Thanks

I might be able to get hold of a cable and software soon. Will have a look and see what it says on the screen at the time.

Dealers do not use VCDS, so I assume giving them a list of channels, bytes and bits would be pointless.

What is tear wipe then?

It's for getting the annoying drop of water that runs down your screen 3 seconds after the wipers have stopped, after using you screen washer.

They might use a different system, but the print-out he gave me of the screen he accessed has exactly the structure described in VCDS (STG/BYTE/BIT).

Whe it gets down to the Bit level, there is then a string of 1's and 0's (eg. 101101001). He assumed that 'activating bit 6' would mean counting along that line of 1s and 0s and changing the sixth to a 1. Could this be where he's going wrong...?

STG 09 on VAS is equivalent to 'Select Control Module' -> '09-Cent. Elect.' in VCDS

Yep, that's the area he was working in...

If he does not know how to read binary code then yes, the code will probably be 8 digits long, the 1st digit is bit 7 and the 8th digit is bit 0.

So if I give you the current binary code in-full for each of the 3 things I want to change, can you reply with what it should be changed to in order to work?

Yes sure, I don't 'normally' do coding by changing the binary code (or the long code directly) but I have done it a handful of occasions where there has been no choice.

You do need to make sure that you are 100% sure you have the correct byte and bit, if you are happy that these are correct for your controller then it is certainly possible.

Hi Gizmo68

So, for the...

Cornering fog lights (STG09/BYTE12/BIT06

Tear Wipe (STG09/BYTE14/BIT04)

Coming Home Lights (STG09/BYTE10/BIT02)

...here's a recreation of what the STG/BYTE/BIT settings are currently on the print-out the mechanic gave me:

Vehicle system

09 - Electronic central electronics

008 - Coding (Service $22)

Select coding value

(I have had to attach the table below as an image as the message board formatting could not keep the columns in line)

If you can say what the relevant lines should be changed to, that would be hugely appreciated!

Thanks in advance.

Thanks v much Gizmo68, much appreciated. I'll take these into the dealer next week.

It took me all of 5 minutes from connecting the cable to the car and opening VCDS.

I now have cornering fog lights and tear wiping working.

The coming home lights are not working at the moment but it may not be dark enough to activate them.

Many thanks Gismo68

Put your hand over the sensor...

I cannot get the "coming home lights" to work, all the rest do.

On the mkII octy one of the settings needs to be set backwards, something about personalisation, set it to what seems to be the wrong one.

This is from memory and may be wrong.

OK Where is the sensor for the ambient light?

I did managed to get single door unlock to working by coding Byte 0 Bit 0 (not bit 5)

Its the one for wipers on the windscreen. If you don't one it will complicate things.

Tried coming home lights STG09/Byte10/ Bit2 with no luck so I tried the others in turn 1, 4, 5, 6, 7 but still no luck

The one on our Citigo windscreen is the City Safe sensor?

I think that is completely different.

What happens if you leave the headlights on and turn off the ignition?

Finally got booked in at the dealer this morning - they used the codes and all worked perfectly.  

Thanks to Gizmo68 - this is the Skoda Community at it's best!
