BillT, welcome to iRV2.com. We are glad to have you join us here and look forward to reading of your adventures and experiences. Good luck on the autopark brake issue. Once you find and repair the problem you may want to find a shop that uses the BG flush system and have the fluid completely flushed, system cleaned and new & conditioned fluid installed.
