What is this?

[Cromanian]

I bought a 325i sport and there's some kind of water bottle above the rear drivers side arch. Also I must replace a bushing on the same side, is it possible to replace one without taking off the whole arm?

the rear wheel arch???? or at the rear of the wheel under the bonnet?

what bush will you be replacing?

[dips346]

the bottle will the vapour/overflow bottle in the rear wheel arch

[Cromanian]

I need to replace a bushing in the rear on the drivers side, the bottle is under the arch near the petrol cap

re the bushes, theres trailing/swing arm bushes, subframe bushes and top mounts
