Afternoon all. Hope somebody can shed some light for me. I have a 2010 Leon fr 170bhp. Accelerated hard in 1st gear the other day and since then I've had a rattle. Originally I thought exhaust heat shield but on closer inspection it's the fan on the pulley wheel under the alternator pulley. Is it just a case of tightening the bolt myself or is it a garage job? I've uploaded a video to YouTube but as it's my first post not sure I can add a link. Thanks in advance, Dave.
