VCDS (VAG-COM) codes and programmable options for Golf Mk7

[33ASY]

Thought I'd add that when I lock the car (with the key or door), the lights do turn off. They just can't turn off while driving.

Hey Don,


I'm after some advice regarding your tweak for instrument cluster lighting.


I am finding that with window tinting on a overcast Brisbane day, the instrument cluster often dims to a point where it's almost impossible to read. I have the head lights set to come on "Early" which reduces the duration of unreadability.


I have applied your recommended values for daylight or "X" and found the situation to be a bit better. However, it looks like I would have to tweak the value of X5 further so the cluster stays lit up until the headlights come on, and leave the "Y" values as factory to maintain the dark-out reminder to turn on headlights if I ever have it in the off position.


If my understanding is correct from reading your documentation, I need to decrease the decimal value of X5 from 100 to something even lower.

Alternatively, I could half the decimal value of X2 and X3, and this should keep the clusters lit up for a bit longer until the dark-out kicks in.

Is this right?

Also sanity check: X curve = parking lights off, Y curve = parking lights on?

Any help you can offer here would be greatly appreciated

This morning, the oil temp gauge in the MFD reached 56 C (short commute today) but the oil temp gauge in the Offroad Monitor still showed three dashed lines. I found that a bit odd.

My oil temperature begins to register at 50°C. The number in the cluster has matched the Offroad gauge every time I've noticed it.

Answered my own question. Halving the X5 value in Don's spreadsheet has done the trick, so it would appear. Time will tell.

Also Don, not sure if you are aware, but I think the photo transistor is actually on the side with the Tacho, not in the middle under the MFD as per your literature. I have attached a photo, it's the round thing next to the high beam indicator.

It is the only area that responded to my focused spot light.

Agentthumb: Sorry that I couldn't get to you sooner, but I'm glad that you sorted-out your problem.

Had I responded sooner, I would have suggested that you download my macro spread-sheet and try different lighting curves HERE.

The X5 value is certainly the fixing-point for the greatest daylight illumination, but you might find that the cluster illumination needs a tweak at lower ambient light levels. It's a bit of a compromise really between increasing the illumination on the cluster and not having the other phototransistor controlled items too bright. You could of course also tweak these other curves, if you have the interest.

But if you are happy with my tweak curve, then there's nothing more to do (mercifully)
Cheers
Don
PS Thanks for the location of the phototransistor - I think you are correct - that looks like the spot

Ahh I wasn't clear, I did use your excel doc, and halved the X5 value in the red field from your suggested value. (I was already running your suggested value prior to tonight's tweak)

Thanks again!

Enable WLAN on Discover Pro MIB1
Warning: you will not have data access if you don't have premium telephony, so there will be NO online services. This WILL lead to an error in Phone menu when selecting "Premium phone". It will do no damage, but as with all VCDS changes: use your brain.


Module 5F
Login 20103
Long Coding:
Byte 15, bit 4 = 1 (Phone NAD)
Byte 24, bit 3 = 1 (WLAN Module)
Adaptation:
WLAN: On
(7)-Vehicle configuration-WIFI_Hotspot: On
(17)-Vehicle configuration-UPnP: On (Will enable DLNA)

After you've set this, RESET the device by holding Power for ~15 seconds.
You can now find the WLAN settings in the device settings menu.
If not, that's bad luck. The MIB1 is a mysterious device... it could be that you need to set "LTE Module" to on...

That's all.
Feel free to experiment with this. Be careful though.
Please post your findings here!

Some stats

My Discover Pro FW 192 - WLAN enabled 1.5 years ago https://www.drive.net/l/4359571/
My Discover Pro updated to 388 - WLAN doesnt show in Menu, but show as inactive in Media Source...
Columbus SW 390 (same as Discover Pro SW 38 - WLAN activated successfully https://www.drive.net/l/8898320/
any ideas why dont work with 388 DP?))))

I have 0388 myself and it works.
However, you should look at these things in a seperate way:
- WLAN Hotspot
- WLAN Media Source.

WLAN Media source is only available when you have a DLNA server running on your WLAN network. Otherwise, there would be no source.
You might need to re-enable WLAN again after updating. Updating sometimes resets some settings to what VW wants them to be.

I spent yesterday around 4 hours to attempt to activate the WLAN. And I tried all combinations =)

Including a reset?

Yes, of course =)

Query for all the people that know a lot more about VCDS than I do.

For cars with DCC would the damper values be able to be changed somewhere in the system??? There are obviously values stored so when you change between modes the voltage to the adjustment valve changes.

If you change the springs and they have a 10% higher spring rate if you could adjust the damper values up 10% it would assist controlling rebound. The compression stiffness would obviously be higher from both the spring rate and damper compression.

Monkeysrus: I don't have DCC, but I suspect that the answer lies in the suite of adaptation channels for J250 (which resides at address hex14 on a mk7). Here is an admap for J250 from my database for an RoW vehicle:

If you have DCC on your car, you might consider "intelligent experimentation". Hope that you don't need a security code

Great info as always, thanks Don.

I wonder if looking at the current values when the car is in normal mode and once again in race mode ill be able to identify any difference???? The last few could be of interest!

monkeysrus: Hmm....... I really don't know the answer to your question as I have never played with this control module.

I'm guessing, but I suspect that nothing will change because the adaptation channel 1)-Constant current loading mode-Constant current loading mode; activation is set to off . I suspect that none of the "constant current" channels will show anything but zero as long as this channel is not active. I also have no idea what forcing a constant current value into the individual suspension tubes will do - please provide feedback if you try different values (I'm interested from an a academic perspective)

Perhaps a better way to investigate (before changing adaption channels) is to use the "Advanced Measurement" facility in VCDS first. I'm not sure what parameters are available in this control module - but might be prudent to "rummage-around" in this part of VCDS before modifying adaptation channel values

Cheers
Don
