I just paid £47 to bmw to instal a new rattle today.
Had one at the very rear of the car that comes and goes occasionally. Since I booked the car in 3 weeks ago it stopped but when the car was in for the booking today they investigated it.
They found it was the b pillar which confused me as that's the middle of the car.
Drove the car up the road to hear this new rattle.
£47 for a rattle is a bargain I thought.
