'20 GLC-63 w/ P002477 Code - No symptoms
Hi all,
I am having a reoccurring issue of a P002477 code popping up during diagnostic scanning. Car does not have hard starting issues but has always had a slight juddering/jerkiness issue when moving from a dead stop. That juddering, to me, was always more related to normal operating of the 9 speed MCT but maybe I'm wrong?. Dealership had the car a week ago and cleared the code since there was no hard starting or other symptoms. All this was prior to loading a Stage 1 tune. Once dealership gave it an all clear, I went ahead with tuning. During test runs after the tuning, car through hard CEL with a P0302 misfire on Cylinder #2 and P002477. I already had new coil packs at home (A177-906-0206) so I went ahead and swapped out the coil packs to have that out of the way. P0302 is cleared and solved but the P002477 remains. Car tuning was returned to fully stock and run great (great as stock can).
Any thoughts on resolutions for the P002477 code? I feel I need nudge the dealership in the right direction on this since all they did last time was clear it and cross their fingers. What to do with a code like this and no apparent symptoms?
