What this video covers
Bobby purchased a 2012 Fleetwood Providence RV, but the vehicle triggered a "stop motor" warning and leaked coolant into the exhaust system less than a quarter-mile after leaving the dealership.▶ 1:31 A mobile mechanic confirmed the failure of the EGR cooler, which allowed engine coolant to bypass into the exhaust stream and potentially contaminate the diesel particulate filter (DPF).▶ 4:59 The repair requires replacing the EGR cooler and potentially the DPF, with estimated costs ranging from several thousand dollars depending on the extent of the fluid contamination.▶ 6:32 The dealership agreed to cover the repairs, and the RV is scheduled for towing to a service shop in Nashville.▶ 7:05 Bobby utilized Good Sam insurance for the towing logistics while managing the repair timeline around a scheduled trip to the British Virgin Islands.▶ 5:59 Modern diesel emission systems, including EGR coolers and DPFs, are prone to failure when coolant leaks into the exhaust path, often resulting in immediate engine warnings and significant repair costs.
