Hi, I'm not that mechanically minded - I once overfilled my car with oil to the point that oil came out the air filter. Problem - when I turn my wheels in an entire lock, I get a loud BOING / TWANGING noise from the drivers side front wheel. I've also noticed that the steering goes a bit wonky when I reverse and turn. Can anyone tell me what this means? I know if I go to a garage, they'll conjour up a whole bunch of other stuff to fix unless I know what the problem is. I've just got a regular 1l unmodified lupo. Thanks for your help folks, Max
