Hey guys. Long time lurker first time poster here. I have a 2007 a4 s-line and last week the regulator in my driver window failed. I followed this tutorial (http://www.audizine.com/forum/showth...lator-Tutorial) which was super helpful and I was able to fix it and saved lots of $$$. It worked perfectly for a few days, however, this morning I rolled up the window and once it closes there is a loud grinding noise like the motor is still trying to close the window even though it is already closed. This doesn't happen when lowering the window and there is no grinding or any bad sound while the window is going up and down which makes me think the new regulator is fine but there is some sensor issue with the motor. Has anyone experienced this or any thoughts on what could be causing it or how to fix it?

Many thanks.
