Hello everyone, I dropped my car off tonight and got a 330i as the loaner. I will update with the findings when they become available.
Timber71, Ask to see the old parts and if they flushed the engine to removed any metallic debris. Make sure they document all the defects that were found and corrected and that the intake side was checked and no defect noted. This info would be advantageous should the problem recur....Good Luck..
