I have a 2022 P300 Base model 110 which has run flawlessly for just over 2 years. In late November I took it to the dealer for its annual oil change (I've been doing ~5000 miles / year) and "21,000 / 2 year service" even though it's only done 10,000. I did also have the oil changed a year ago at around 5000 miles. I then left for a long-ish trip to Canada - 450 miles pretty much straight through in 8 hours or so with most of the journey in below freezing temps.

Parked the car at the airport for a week, then headed back. Everything fine for the first 200 miles or so and then there was a check engine light and a whine from under the hood. Car went into limp home mode - which was a little scary on the NY State Thruway. Ran the codes when I got home and it was mostly turbo pressure and a bunch of other safety airbag codes that I presume are related to limp home.

Had the car towed to the dealer who have replaced the turbo under warranty.

My questions are: we know that turbos are killed by lack of oil pressure or contaminated oil - could this be related to the dealer having changed the oil a few days before? Stirring up dirt in the pan? Failing to use the crochet amount or grade of oil? Failing to prime the filter? If so, there's probably nothing I can do about it after the fact.

Anything else I should look for now the turbo has been replaced? I still have two years or warranty and I plan on keeping the vehicle long beyond that - but want to look for any issues that may be related to this turbo failure
