Hi

I was driving with my dad today. He accelerated hard to pass a truck. The gearbox kicked down and the car was just starting to accelerate when there was a loud bang that sounded like a gunshot. I can't remember exactly where the bang came from but it didn't sound like the exhaust area. Now the car won't rev past 2k rpm unless you manually change down. I think this is 'limp home' mode? We're going to call the local dealer in the morning. I'm just wondering if anybody has any ideas?
It's the 2004 S320 CDi - done 78k and has the 5 speed auto transmission.

Thanks in advance
Ollie
