I am so glad you sent that You Tube... last summer my car was in the shop because it was running a bit roughly, but only sometimes. They ended up replacing the engine... thank goodness it was under warranty so I only paid my $100 deductible.
I'll bet that all it really needed was for the?turbo-encabulator to be recalibrated.
First thing Monday morning I'm going to go give their Service Manager a piece of my mind (if I can find one too spare).
