I used Pentosin DOT 4 LV. Available online or locally.Also, what does this entail with the brake fluid change?
Purchase a Motive Power Bleeder with the European adapter (Amazon).
I used a Mity Vac to suction out the reservoir. Fill the reservoir with new fluid, add fluid to the Motive, attach, pressurize.
Start at the calipers farthermost from the reservoir. Bleed.
You DO Not need to use the VCDS procedure unless you replace the ABS pump, or run the system dry.
Search YouTube, Vortex, etc. Lots of DIY vids.
