New to this forum. I have a 2015 VW Golf TDI with 56,000 miles on it. A couple of months ago, Dpf light as well as glow plug lights came on- both solid. The Golf is also in limp mode. I attempted to drive the car and burn off the extra soot with no luck. Shortly after, I attempted to perform a forced regen, but it wouldn't take. Brought it to the dealership to cover the dpf under warranty, and they denied me. Dealership said it was in need of dpf replacement. I replaced the dpf myself, but after replacing, I am getting the same lights as well as still in limp mode. I attempted to drive 15 minutes around 2k to 2500 rpm's, without any change. Any suggestions now that the dpf has been replaced?
