Hi everyone,
I want to replace my ST 2018 shock absorber but don't know where to change it to be safe because someone said it has a problem. What do you think about the error story in the anti-collision system? What should I do to change to a safer and more suitable device?

Never heard of this, I know the headlight levelling sensor is attached to the shock and can cause issues if it's not changed properly

Sounds like something you never want to go wrong, personally I'm not a fan of those systems and I didn't spec it when I bought my Focus.
