Recent strange noise from engine bay

Post by Mr K Alpina » Wed Mar 13, 2013 3:28 pm

Over the past few days I've noticed my 2009 D3 BT is making a very annoying (albeit not particularly loud) noise from the engine bay on idle. The car seems fine (e.g. power steering ok, brakes ok) but the only thing I've noticed is that when lifting off the throttle, the car doesn't glide so much. This is a very subtle difference however.
Difficult though it is, the only way that I can only describe this noise is it sounds like a toy train. Or if I could spell the noise its: "Fut-Tsch" for every second that passes.
I haven't had the opportunity to try and pinpoint the source, but as I'm on the website I thought I'd mention it and see if it's something anyone is aware of?
The car is due for it's MOT soon so I guess I can ask the garage to have a closer look.

Have a look for loose pipe / tube around the turbo area - have someone rev the car whilst you look / listen ...

I'm pretty sure the power steering on the BT is electric rather than hydraulic. I'd place my bet on a belt from the noise you describe.

Does the BT have all of the efficient dynamic gubbins on it? Maybe something to do with the freewheel mechanism?

I asked someone who had a lot of experience with the BT and
A Distinguished Gentleman wrote:...the V-belt is often troublesome on those engines and it may be that...especially if it has a sharp 'whiplash' sound on start-up. Joe is correct about the PS, too
so perhaps that will help with the diagnosis

I think it does make a clatter on start-up (excluding the diesel sound)
Is it something that should be looked into immediately or can I wait until the MOT in about a month's time?

Hello, Mr K, I'm not sure anyone would dare answer that last question by saying you can wait a month. [Though you never know!] Well, I wouldn't anyway.
If you are worried enough to ask the question, my advice would be to get it checked out ASAP. Ultimately the answer to whether you can wait a month will depend on what the problem turns out to be........ :wink:
