dropped the car off this morning at the dealership ~1hr away. Yesterday in addition to the blinking glow plug and MIL I also had a DPF light on the dashboard (Hadnt seen that before). Dealership is assessing and said it could be 2-8 weeks for a DPF and will keep me posted. I didnt hear anything from them today but will call and get an update on prognosis tomorrow. Are there other items that typically need to be replaced with the DPF such as the EGR valve etc...?
