Hi.
My car is 02 TT Quatto and it uses MacPherson strut style.

Coilover is 4 months old, and all other components are 2~4 months old except 22 yr old control arm bush. Only 73000mi.

Front left suspension knocks/clunks over bad roads and bumps. Only when it is cold outside. New strut mount bushing, new sway bar bushing, new sway bar links, new ball joint installed already. Only thing that is not new is control arm bushing. Over 75F, it does not knocks, or maybe very small knock but I can’t hear due to road noise. So I think these are temperature dependent. What can be the issue, coilover itself or control arm bush?

installed yourself? check the bushings. did the coilovers come with new tophats?

#

check all the things you installed. I wouldnt put much time in the cold weather thing i dont think it will lead to much. unless you thing the shock is defective and reacting to the cold.

#

no rubber or plastic isolators on the spring? it that a budget design? MacPhersons strut can make spring noises.

#

did you adjust the height and or preload?

Double check the torque on every fastener you touched. Use a torque wrench. If everything is to spec, do the control arm bushing.

Installed by mechanics, and I do checked it that they tighted everything pretty well

Maybe change the adjustment and see what happens

#

Usually the preload is the ring on the shock and the whole shock body spins on the lower mount to adjust height.

What shocks are they
