I am comparing my 2008 M5 with my friend's 2006. There are 2 major mechanical differences that have me thinking.
1st, my motor makes a more throaty burbly noise when revved and it's definitely louder than his. When revved his goes voooooooooooooom, mine goes voom burble vooom burble vooom.
When I let off the gas on mine it feels like the motor is twisting (this is in N in the driveway), his doesn't.
Of course, when cruising on the highway the cars are indistinguishable except for the additional rumble of my motor. Any ideas why that may be?
2nd difference is the SMG downshifting to 2nd. Mine clanks (not all the time) when slowing down to a light/stop sign and going to 2nd. His is completely silent.
So, the final question is, do these cars differ that much in sound and behaviour or should I be asking the dealer to check things out?
Thx

Welcome to the forum!
I haven't heard of any mechanical differences between the pre LCI vs LCI M5s and the only thing I can think of is that your car may have the latest software and his doesn't. Chances are unlikely that newer software can affect the sound of the exhaust but who knows. Probably better chance of it affecting the way the transmission shifts though.

aren't the SMG's and VANOS known to be problematic with early build M5's...

Yes, but mine is an 08 and his is an 06 and mine is the one that's noisier all around.

Is it possible that you have an aftermarket exhaust?
While I was recording this, I paid more attention and I can actually feel a slight vibration in the driver's seat as the car burbles when revved. It definitely feels like the engine is twisting a bit.
