Previous car was the infamous BMW N47 320d, so I'm fully acquainted with hydraulic tensioner failure, but that had a hydraulic tensioner plus a mechanical one just for good measure!

No oil line .. The hydraulic tensioner does not fail, it is just too stiff in cold weather and overloads the belt when the engine fires up initially .
