Engine Pop Sound on 1st gear acceleration (ecodiesel)
Have had my Eco diesel for 2 months now (3k miles) and it's been great and have had absolutely no issues until today. I noticed that when I go from a full stop and start accelerating in first gear my engine makes a loud popping sound like the gear isn't catching correctly and almost skipping a gear during the initial acceleration. I tried accelerating slowly to see if I was pushing the throttle too hard but the sound occurred randomly and sometimes was completely fine. It got to the point where every time I went from a full stop I was bracing for the sound to happen. Any time the sound occurred it sounded like it was coming from the engine but I could also feel it near my foot like something was caught underneath (nothing appeared loose under the car).
The sound was loud enough that the cars next to me definitely heard the sound as I started to accelerate from traffic lights. Has anyone had this same issue or can help point me to what the problem might be? I plan on bringing it in this week to check it out but it is definitely concerning as I wasn't expecting to have issues with a brand new car this soon.
