A collection of many VCDS tweaks in one posting

OBD Scanners - TDIClub Forums - forums.tdiclub.com
After I got my 2015 Passat I did a lot of searching for different little tweaks to be done on the car. I found some in Audi forums, Golf forums and other VW forums. I have done and use many of these different tweaks. Some may not work on your vehicle and may require your vehicle to have equipment that may not be on yours.

I am not responsible if you do something that will cause a malfunction on your car. Use these at your own risk.

Auto Closing Sunroof & Windows via Rain Light Sensor

Requires the (RLS) light sensor. RLS may not be present on some 2013 models. If there is no drop down menu in Coding then you likely have no RLS. This will require coding the master [09] - Central Electronics module and the Sub-System RLS.

[09] - Central Electronics module using Coding, Long Coding Helper

Byte 4 Comfort Operation Windows/Sunroof via Rain Sensor must be enabled

Byte 4 Comfort Operation Windows/Sunroof via Rain Sensor (Rain Closing) active must be enabled

Sub-System RLS (from the drop-down menu) using Coding, Long Coding Helper

Rain Closing active must be enabled

Fuel Gauge and Fuel Consumption Adaption

I've done some testing on a '10 Gti. The Instrument cluster adaptation results are:

"Display correction of consumptions and operating range" found in Adaptation, from the instrument cluster. The value should be 100% from the factory.

Increasing the adaptation value lowered the Mpg data displayed on the MFA. So, If you want to lower the average MPG displayed on the dash, try increasing the adaptation value to 102% -> 105%.

If you wanted to Increase the Mpg on the display, lower the Adaptation value to 95% -> 98%. ---------------------------------------- ---

"Display correction of fuel gauge" found in Adaptation, from the instrument cluster.

By default, this was set to 0.0*. The Max adaptation values are +/- 10. The total range of fuel gauge movement was near 1/8th tank.

Increasing the value to 10*, makes the needle raise by approx. 1/16th tank.

Lowering the value to -10*, makes the needle lower by approx. 1/16th tank.

I dug into this and believe that the sender in the tank has a normal operation range of 70O -> 270O.

-----------------------------------------------------------

Seatbelt chimes

You can have that pleasant chime by going to

17-Instruments->Adaptation->Seat Belt Warning - Version 3

And you are not warned when you go over 74mph!

so you don?t have to change everything else back to US measurements...

Steps to get "Alternate Speed Display" and Large Digital Speed Display

Based on 2011 Canadian Model with KPM Dial Speedometer

When heading down to the United States it would be handy having something showing in MPH. To get this smaller digital display in MPH in the MFD area:

1) Bring up the settings menu and scroll down until you see ?Alt. Speed Dis.¹?;

2) Select ?Alt Speed Dis.? by pressing the OK button;

3) Once back on the main MFD screen you will now see MPH between two lines where the temperature was previously.

4) Above these two lines you can select various info screens by using the down or up arrow. Scroll until you see your preferred choice to display while driving. Also, by pressing OK you can, for certain screens, toggle between Screen 1 or Screen 2.

Screen 1 is the single trip memory. See the owner?s manual for reset limits.

Screen 2 is the total trip memory. See the owner?s manual for reset limits.

Now I would like to share how to display the large digital KPH in the MFD area.

1) Bring up the settings menu and deselect ?Alt. Speed Dis.¹? by pressing OK on the steering wheel;

2) Scroll up and highlight MFD data and then press ok;

3) In the options list make sure ?Digital Speed? is ticked. If not, highlight and press OK;

4) Now return to the MFD display that shows the various info screens and using the down or up arrow scroll until you see the large digital KPH appear. When it appears just leave it there;

5) Now your KPH will be shown in large digital numbers and you will also have the dial showing KPH.

Intuitively, this should work for US model cars, but I am not sure. Feedback is welcome from our US neighbours. I believe you cannot have the larger digital KPH displayed at the same time as the alternate speed setting, namely MPH. .

Auto release parking brake when in gear with accelerator pedal input for Audi's

Select the parking brake module (address 53) enter coding, and simply change the last digit of the coding from 2 to 1 for ROW.

You can now apply the parking brake at long red lights, and use it as a brake hold. When you are ready to set off again simply tap the throttle and the EPB will release.

-----------------------------------

Re-Fueling to empty

In my pursuit to the above topic i came across this VCDS tweak. Not sure about other 2012 Tiguan owners or other new VW models but here in Australia I did not have this function.

Plug your VCDS cable in and access module 17 instruments

Enter the UDS Adaption 10 menu

Select the channel with the label "Volume to be replenished"

Change the stored value from "no" to "yes" and then select "do it" to save the setting and exit VCDS

You should now have an extra option in the MFD settings called refuel

A value will then be displayed once 10 liters of fuel has been consumed from a full tank that will be required to safely refuel the tank to full again.

Not sure if this will work with 2011 models that have a similar instrument panel display but maybe a few 2011 owners can have a crack at and let other forum readers know. I do know from my research on attempting to activate the driver alert system there is subtle differences in the coding between the BCM module 9 and this module with older 2011 pre facelift models.

A Full tank should read near 70O. Empty tank = 270O. You could check the actual resistances with a DVOM at the fuel level sensor in the tank -OR- By using Advanced Measuring Values, check "Fuel Level Sensor 1" (138).

However, I don't think any adaptation modifications are going to correct your concern. If you change the correction of fuel gauge, the actual needle range may become corrupted. After filling up, the tank may not read full, or worse..the empty tank range may not read correctly resulting in the vehicle running out of fuel.

It's possible that the fuel level sensor "G" is faulty. I really haven't noticed any issues with mine. The car only gets 27Mpg, so I don't stress myself out by monitoring this. It displays "Please Refuel" and I find myself filling the tank quite often!

----------------------------------------------------

Finally, after research, I was able to setup service reminder on USA spec cluster. I think is very useful feature, no idea why is disabled on US cars.

Anybody with VAG-COM can do that, by changing coding in your cluster. This only can work on cars with CAN BUS build from 05.00. for example US Golf cluster coding is 07232 so you have to replace 4-th digit (3 with 0 as for cars with fixed service intervals without oil/temp. sender), after this go to:

channel 43 in Instrument Cluster (upper limit for distance to next inspection step size is 1000 km,

by default 15000km = 9400 miles)

channel 44 is upper limit for time to next inspection in days, step size is 1 day by default 365

channel 40 is distance traveled since last inspection, step in 100km (ex. 5200 km= 052)

channel 41 is time elapsed since the last inspection, step 1 day

First, the Channels 43 and 44 must be adapted, because the values of channels 40 and 41 may not be greater than the upper limits of channels 43 and 44.

Adaptation must be done using kilometers (1 mile equates to approx. 1.609 km )

To reset service interval, go to Instrument Cluster Adaptation channel 2 enter 0 and save.

Service Reminder will display on your cluster (in place of the current odometer display, just for a couple seconds) after certain mileage (usually 2000 miles or 3200km or time set in channel 43 and 44, as Service in and it will countdown every 100 miles(km), when you turn your ignition ON.
