Frankberg Window Regulator Withou Motor Rear Left Compatible with X3 E83 SUV 2003-2011 51353448251

Fitted perfectly

The window regulator does look similar to a genuine BMW part but the quality of the fixed bolts and rivets does not appear as good although it should be OK , time will tell regarding corrosion .The top and the lower plastic wheels for the cable seem lower quality and the top wheel on the one I purchased is buckled .Testing the movement of the driving dog from top to bottom and it had some slightly tight spots . I applied a good quality oil to the cables and other moving parts which improved the movement considerably .The window motor did not align perfectly on the mount lugs but it was very near and sequentially tightening the screws helped to seat things properly .One section of the cable sleeve has an additional rubber damper over it but it is a loose fit and required tape to keep it in the correct position .I can recommend this window regulator as it is less than £40 .
