2009 Peugeot 107 banging

Could be many things , rear s/absorber , rear spring , exhaust / heat shield , rear suspension bushes , wheel bearings etc , needs checking to ascertain exactly what is causing it

Many thanks for the fast response. She will get the local garage to run checks on Monday.

That's good .You dont want to take any chances with a car your daughters driving , It's better to make sure it's safe and have peace of mind . Hope it's some thing minor
