Hi Everyone - I'm new to this! Hope you're all well. I bought an Audi A8 2005 SE Quattro 3.0 Diesel 5 weeksn ago. It was parked over night in a secure car park that can't be entered without a key. The car had been undriven for over 15 hours. Suddenly Sunday afternnon smoke was seen comign from the bonnnet and within 10-15 minutes the engine exploded! Has this happened to anyone on here or anyone you know? Is it even possible? I'm totally stumped!!!!
