Hi All,

This morning on the way to work while sitting at a red traffic light i had a massive bump or knock. I actually thought someone had driven into the back of me.
I put the car into neutral/park and checked the rear bumper. No one had driven into me.

Got back in, selected drive and pulled away like normal with no noises or power loss.

Any idea what it could be and what I need to do about it.

It is totally standard so no mods to tuning or gearbox.

Thank you
