live in Montana, went to Virginia to check out our daughters' college (Liberty). Long trip, just bought the RV in May 2019, got to Billings and the engine Check light went on, did not notice until Buffalo WY. Took it to a O'Reilly auto parts store, they were able to tell me what the error code was, was the exhaust filter (P2002) code, which we found was 1345.00, but had to be shipped from Billings--but none of the 4 diesel mechanics would work on a sprinter engine. So, called MBenz and they Towed it up to Billings (large bill for them, none for me, still under warranty). took two days out of the trip of three weeks total. Found out it was NOT the filter but the sensors on both sides. But, after that all went well, rode nice. Had a wonderful trip, did not really like having to drive over 2000 miles back, but found some very nice RV parks to overnight.
