hi everyone, i noticed a noise coming from under my driver side when i hit a bump or when i'm backing up and step on the brake. it sounded like a hammer tap (one tap) the bottom of the car. only on the driver side. know what could cause that noise?

Bloody hell it could be anything, i think though its likely the exhaust moving on its mounts, get under the car and give the exhaust a good shake you'll soon find out!! there could be a bush on the suspension also, but i would start with the exhaust first :D

Oh and welcome to the forum fella :D

ahhh... i have to give that a try to get underneath and shake the exhaust... i was thinking it might be the coil ... can anyone please tell me does our e60 have timing belt or timing belt? thank you

oops! timing belt or timing chain? hehehe

Timing chain buddy!!
