I have a Toyota Corolla Verso bought in 2005. Recently it has started to make a noise somewhere in the steering column. Whilst it is only as loud as a clanking keyring, the odd thing is that the noise is made at irregular moments, nothing to do with speed or turning.
Most odd of all, the car can be motionless (engine running, handbrake on) and the noise will start and stop of its own accord, without anything moving. Yes, with my hands off the wheel!
If forced to guess, I would say the sound is coming from that part of the steering column nearest to the driver's knees. It reminds me of a motorised kids toy that is held so that the parts cannot move, and the internal mechanism slips and jerks. (For the purposes of this test, all children and toys were removed from the vehicle).
If you know what it is - can I safely ignore it, or do I really have to get it fixed?!
