That's useful - do you have a photo or diagram to share? I noted that there is a small deflector on my S4 - but it is 1cm too shallow. I will try to get pictures of the damage when the car is repatriated!
Update on my Aero 1. Repair to front end ~£2500 claim directed towards Falck recovery in DK 2. Repair to sump ~£350 claim directed to Aalborg kommune. At least it's nice in spain!
