4000 mi | Active exhaust valve producing rattle, exhaust system replaced. Vacuum pump and reservoir for active exhaust valve removed under TSB. Rerouted the lines to the manifold for vacuum pressure. Rattle returned 500 miles later. Second faulty active exhaust valve producing rattle. Replaced exhaust system again for the third time. Parts not available, had to wait 6 weeks for part to arrive. Unintentionally disabled my exhaust valves, removing a paid-for feature from the car. |
