Better late than never! Even my spare OEM tensioner pulley does not have a maker's name on it - just the part number, 'BMW' and 'Slovakia.' Why are you set on having a pulley made by an OEM manufacturer anyway? All you will get is a similar component made by an anonymous manufacturer in eastern Europe! You may as well go to German & Swedish . . . In terms of life, my original Z3 aircon tensioner pulley began to get noisy at about 100,000 miles, while the belt tensioner on our Golf TDI remains original at over 240,000 miles and 24 years. Admittedly, on a realitively low-revving diesel they both enjoyed about the same amount of revolutions.
