Just want to say a big thanks to all who post. Im new to the fourm but have a 14 Grand overland eco and been looking alot at deletes on here. Lots of good info. Just left the dealer for a 100% full filter. Talked to the tech who was cool about clearing it and doing a park regen for cheap. I just ordered Autel Maxicheck Pro EPB/ABS/SRS/SAS/BMS/DPF/TPMS Auto Scanner OBD2 Trouble Code Reader and it says it will initiate a park regen. I will keep everyone informed.
