Hey all, hows this for an introduction to a new forum.. 1st post and ive a problem! Had my '00 S3 for two days now and so far all has been excellent. However jumped into it just now and it wont start.. Dash lights up, but the engine wont turn over. Popped the bonnet just for a looksie and right at the front of the engine bay above the left-hand fan there is a metal cylinder with an electrical connector which is making a clicking/whirring noise. Now im presuming it has been doing this all night since i last used it, hence my flat battery.. Its right in between the two pipes that you can see in the pic. Anybody know what it is/does? And if i can unplug or sort this out now? Many thanks. Phil P.S loving the info on this forum so far!!
