My car is a 2015 Golf Sportwagen TDI, SEL trim, manual transmission.

The only things I'm going to put here are things I know work on my car.  They might work on other MK-VII VWs, but I haven't tested.

Here's some Useful Info

What I've done

• 16" wheels (more comfortable, *way* cheaper tires)
• Turn off "comfort signal" three blink lane change
• Disable rain sensor / auto wipers
• Turn off "beep" when locking
• Turn off auto-lock when driving
• Unlock all the doors when unlocking one
• Turn off door trim lights (that stripe below the window)
• Turn off Daytime Running Lights (add clickbox in head unit)
• Tinkered with the power steering response (ended up leaving it stock)
• Enabled the two inner running lights as brake lights
• Tweaked the in-dash fuel economy to match reality (in progress)

What I'm working on

• Amber LED rear turn signals
• LED brake and running lights
• Convex driver's side mirror: No blind spots!
• Towing hitch
• Audi TT front control arm rear bushings
• Open all the windows and sunroof with the key fob and door button
• Close all the windows and sunroof with the key fob and door button
• Make the radio stay on until the door is opened, (or longer), not just until the engine is stopped.
• Panzer plate (or similar)
• Tighten up steering response

Someday stuff, maybe

• Stiffer springs, (but not shorter)
• Better dampers
• Limited Slip Differential
• MIB-II radio upgrade (for Apple Carplay)
• "Cluster Staging" / "indicator celebration" (tach and speedo needles dance when first turned on)
