I've got this error (P0299) on my 2019 Diesel Ram at 21,000 miles. Also notice it has a bit of a surge under load, which seems to have been there since it was new. Now that I'm watching the turbo pressure on the dash I see that surges at the same time. Went to Dodge in Fairbanks and was told they can't even look at it as they are booked out 2 weeks. Should I be driving it while I wait? Considering I paid them over $70K for this truck I not to happy about the wait.
