Took my m4 to Mt View today for first service (1550 miles)

Drop at 8.45a and pick up at 4pm.

So interesting side note... When the lot boy was retrieving my car it sounded loud, similar to cold start in the morning. I jumped in and drove away but the car exhaust note continues to be louder than before. The car is a tad peppier than before as well (not like it was lacking). At first I thought I was dreaming it but then I picked up my girl friend and she said spontaneously that it was louder so it's not just my mind going.

Any ideas why the exhaust note would change? Valves stuck open suddenly. secret software flash? I wasn't told about.

Also I previously tried to use launch control (before service) but I could never get it to come up. I mentioned to the service writer but there was nothing they did supposedly to enable it - he said it's there and implied I may have not done it right.
