Well this is the end of week three for the repair for my DRC system.
Week one - drop off week - parts were in - or not in - two left side control valves, need a left and a right.
Week two - right and left valves in, installed, On-Star module changed (but not coded at On-star). Pick up last Sat, rear shocks clunking, handling terrible, On-Star not on. Took car home, dug out On-Star, called in ESN and SIDN to On-Star, got On-Star working and phone also, had to eat left over minutes since dealer did not take note as stated of how many minutes were left. So I planned on taking the car to another dealership, got half way there, got call on my cell phone from the original repair site, he really wanted me to let them try again, so I turned around and brought car back to them and got a nice loaner (A6 ) , now end of week three waiting on two rear shocks.
Week three - they located and ordered two rear shocks (right and left) but still reluctant to order front shocks as well. So far no word on parts, but expect them in today! Perhaps they will have the new rear shocks in early next week.
Moving tomorrow, truck all loaded, leaving at 5 am, trailering the A6 loaner so I have a ride back home after the move to apartment. LOL.
Next step after DRC is repaired, new tires - going with PS2's as they appear to get the most complementary comments here and I have had them before on an M3.
