I waited until the warranty-running-out trip to the dealer before protecting the lower grill, and got a large stone through the gaps under the bumper last week. At first the dealer said it was the ac condenser, then the intercooler, then the ac and at last we agreed it was the intercooler and OK to drive it quietly, at least for a few weeks. GBP 1300 here plus fitting, but GBP 400 in the UK on Fleabay, so that will be in my suitcase returning from my next trip over, plus plastic grill mesh. Don't hesitate, protect it NOW! And thank you gloucester for the tip and photos.
