My wife's 2015 TDI is on year 3. I finally got around to flushing the brake fluid from all four calipers. I got lucky in that all 4 of the wheel spokes had given me a clear shot to all the bleeders.
Thankfully VW has hinged the access to the Master Cylinder. One still needs a funnel to get the fluid into the M/C as there is a metal panel above the M/C but I have lots of funnels so it was not a big deal.
I put my plastic tubing over the end of the bleeder with a loose overhand knot in it with the other end into the drilled-cap of an empty windshield washer container, the 11mm open end wrench to loosen the bleeder and I step on the brake pedal to get the fluid moving out of the caliper/lines, keep adding fluid to the M/C to make sure it does not go dry, and repeat on the other 3 wheels.
Now we're good for another 3 years.
