This section covers miscellaneous tweaks that I have done and have found useful. I have several VW automobiles and have relied heavily on the excellent information posted by other VW owners on various forums. Thank you!

You take full responsibility for trying any of the following!

Note that you will require a VAGCOM cable and VCDS diagnostic software for your automobile.

Item Automobile          Description Directions Reference      
1 2010 VW Tiguan Enable locking of the doors with a second key FOB. This is predominantly for those in cold climates that might want to let the car run for a few minutes to warm up. Note that apparently the user manual recommends against warming up the engine by letting it idle. Turn Bit 2, which is Remote Control with "Terminal 15 On" inactive, under Byte 4 under Coding in Module 09, Central Electroncis. golfmk6.com
2012 VW Jetta Turn Bit 2, which is Remote Control with "Terminal 15 On" inactive, under Byte 2 under Coding in Module 09, Central Electroncis.  
2018 VW Tiguan Enter the security code and then set Access Control to 1 for "Funk bei Klemm 15 ein to Active" under Adaptation for Module 09, Central Electronics. golfmk7.com
2 2010 VW Tiguan Often called convenience lane change signal or comfort blinker, the default is three "blinks" when you lightly tap the signal lever. I have changed this from three to five.
2012 VW Jetta
2018 VW Tiguan Enter the security code and then set the number of blinks to 5 for "Turn Signal Controls-Komfortblinken Blinkzykien" under Adaptation for Module 09, Central Electronics. ross-tech.com
3 2018 VW Tiguan Display the number of LED bars on the fan knob, which corresponds to how fast the fan is turning, when in "Auto" mode. By default, no LED bars are illuminated. Turn Bit 6 on under Byte 11 under Coding in Module 08, Auto HVAC. ross-tech.com
4 2018 VW Tiguan If you upgrade the left inner rear tail light from the default North American fixture to Euro one with a rear fog, essentially the reverse light becomes the fog light on the left side. Enter the security code and then set the new value for "Au├čenlicht_uebergreifend-LDS_mit_Nebel_Schlusslicht" "Yes" under Adaptation for Module 09, Central Electronics.

Also set the new value for "Leuchte28RFL LC11-Lichtfunktion A28 to "Nebelschlusslicht wenn kein Anhaenger gesteckt", which tells the BCM to use the rear fog lamp in that position.

Note that you must have the Euro light switch for this to work. The step by step guide by type17volkswagen on the vwvortex.com forum is excellent.
