onto bmw ista diagnostics and go from there, first thoughts, compression test, if all good I would lean towards timing chain & vanos solenoid valve (especially if there was an 02 lanbda sensor error) and a walnut decoke. If your mileage is north of 70K i would be putting a bmw chain kit on as a matter of good practice and engine health.
The garage you last left car to, I respect, they have not the ability to repair, put their hands up and told you who to see, they could have dicked about for days, charged a fortune and not fixed the issue.
