My wife had just bought a new UP! and it's engine noise is louder than the one we took for a test drive. The sound is similar to a leaky exhaust, although it can't be that as only done 15 miles. I wondered if anyone has a similar issue or whether it normal. I have also ordered an Up! and collect it in couple weeks so will see how mine compares. I did speak to the VW garage and they tell me the car will become quieter after a few hundred miles?
