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

[zloybob]

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

Ill see if I can get in this weekend and have a look around. Maybe the current loading mode shows the base value in comfort mode when the voltage value would be 0????? It could be the admap was read with the car ignition on and no voltage supplied to dampers????? (I don’t understand how an admap is read!)

Someone else must have explored this as an option????? I have searched and found no threads / info.

Tried this today, to try and dim the LED DRLs while the blinker is on
Address 09:5Q0 937 084 AJ recoded (ADP-(12)-Leuchte2SL VLB10-Lichtfunktion E 2) from not active to Blinken links aktiv (beide Phasen)
Address 09:5Q0 937 084 AJ recoded (ADP-(15)-Leuchte2SL VLB10-Dimming Direction EF 2) from maximize to minimize

Address 09:5Q0 937 084 AJ recoded (ADP-(12)-Leuchte3SL VRB21-Lichtfunktion E 3) from not active to Blinken rechts aktiv (beide Phasen)
Address 09:5Q0 937 084 AJ recoded (ADP-(15)-Leuchte3SL VRB21-Dimming Direction EF 3) from maximize to minimize

And it works.
But I want to just dim the light, so I tried:
Address 09:5Q0 937 084 AJ recoded (ADP-(14)-Leuchte2SL VLB10-Dimmwert EF 2) from 0 to 26
Address 09:5Q0 937 084 AJ recoded (ADP-(14)-Leuchte3SL VRB21-Dimmwert EF 3) from 0 to 26

Which didn't work - the lights just stayed full bright. I also tried setting the direction to maximize, but it didn't change anything. What am I doing wrong here?

Bob: hi - you have an interesting way of thinking (which is a good thing)! I don't have the high-end headlight assemblies on my mk7, but my understanding is that the 2 x Leuchte-sets that you mention perform the following two functions on LED based fittings: DRL- on the AB alpha pairs and parking lights on the CD alpha pairs. By placing the new DRL "wink" function on the EF alpha pair, don't you get a conflict with the parkers? That is - doesn't the DRL wink still happen when the parkers are on (which it shouldn't)? I'll confirm later, but I suspect that a better arrangement might be to swap your settings for the CD and EF alpha pairs.

My understanding is that EF should have higher priority than CD and AB. Swapping them doesn't explain why it works when set to 0

Had a little look around. You are correct nothing seems to change when i change the modes with the car running and re read the module.

The options under the loading mode are as follows:


Driving mode i assume relates to the switch-able mode in the car. How do i get the the values related to the subset of information??? Comfort, Normal Race etc???? Why would it be off and not driving mode??????

Ill rummage around further!
