Hi all Love the site and have found a lot of answers to my many questions without the need to post..so far! I have a S3 L&K DSG with which I have had no issues...until now! Had the car from new in May 2019 and have covered 32k unevenful miles. Parked up the other day as usual. Returned to car a few hours later to find that when I hit the start button, the starter motor span up and kept trying to start the car but couldnt or at least didnt. Did this a few times and no error messages appeared which I thought was odd. I went through process of turning car off, locking, unlocking but the same thing kept happening. The only thing that was different on the previous journey was that I had to switch off the child locks to let my rear seat passenger out. In frustration I hit the child lock buttons again and then the car started. Not sure if this was just a fluke and not related but thats what happened. Was just wondering if anybody else had anything similar happen to them, ie starter motor spins incessantly but car does not fire up? Hasnt happened again by the way, well so far! Thanks in advance.
