Just had a new cambelt done and started noticing a low pitched humming sound on full lock at low speed, any ideas please anyone?

If it started to occur after the belt job, look no further than taking it back.
Let them see it, listen to it.
As the belt replacement was done no long ago, it is still under warranty



With regards to the noise, it could be either the wheel bearing or the belt tensioner???

Let us know
2.0TDI 187bhp 395Nm = 70mpg

On my B7, I get a low humming noise on part left lock. I seldom use full lock, but have the car in on Wednesday to try and identify it.
Will post results when I know. them.

Sorry for late reply, the belt was only done about 10 days ago. Thanks for your advice, I will give them a ring next week and see what they say. Not overly worried about the noise to be honest and just put it down to being on full lock, but will ring them anyway, cheers..

Like all the best faults the noise would not reproduce with the technician in the car, though, this was after a 20 mile trip to the garage so perhaps it happens more noticeably when the car has been standing (overnight say). Anyway it was serviced (60k), and the the steering and suspension were thoroughly checked and no problems could be identified.
It's definitely still doing it though! :???:

I think it could be something to do with the auto lock brake??

That's interesting; what does it do and how could it interact with the steering?
