The promised video to DIY DCT fluid change. EDIT!!! Make sure to use ISTA+ and use the "Service Function". A German Forum member said it would make a difference...I didn't believe it. I re-checked my fluid level again using ISTA+, and there actually was a 400ml difference. I know that's not much, but still better to be safe.
I've added the ISTA+ bit into the video...it's just an overview of using the program when performing the fluid fill.
