I've been told this could be a major issue, ie Camchain stretch! It's just gone into limp mode as in no boost whatsoever and a hill is virtually a nono 😔 the thing I don't understand is that usually with a stretched chain it'll make for a pretty noisy engine ie rattles etc this is super quiet, not a sound. Also it's been suggested it could be a dpf sensor being faulty throwing out a suspect fault code!! Guys.... I could really do with some help which I'd truly appreciate. 🙏🙏🙏

 

Has it been scanned for fault codes?
