Anyone know what whirring sound of engine might be - I have noticed it before but seems louder recently . Making the whirring sound in Lower gears and higher revs can’t notice it below 2000 revs and no noise when stationary.
might just be the normal noise of engine but not had the vehicle that long 2009 1.9 T5
Thanks

Sounds like a bad bearing on the aux belt. Will definetly be something on that side i would say. Get someone to rev it and take a look see if you can pinpoint it.

There's an idler wheel and tensioner wheel which both have bearings. Check the state of your auxiliary belt - it's pretty easy to remove and refit a new one (just done mine myself). With the belt off, you'll be able to spin each of the pulleys by hand and see if they're running freely. Replacements are pretty easy to come by.

Thanks for the advice much appreciated

Definitely a bearing has gone, if it doesn't make a noise when stationary and revved, it's nothing to do with the aux belt, or cam belt, it's the gearbox input shaft.

Wow! Just listened to that video, It does sound like a gearbox bearing. You shouldn't drive it much like that because other damage will be caused. Mine made about half that sound and the fault was the input shaft bearing as bluezie suggests. The problem is that the bearing can turn on its shaft and machine it down. Unless the damage is very light this results in a gearbox strip to replace the parts.

They will probably only be interested in an exchange box. There are specialist gearbox places around who will repair yours but check all feedback carefully. If you are near the Midlands Ian Peck in Wolverhampton has a lot of experience with T5's. It is an expensive business unfortunately especially if you factor in a new DMF and clutch which is probably worth changing unless you know their history already.
