Whining Td5

Td5 was pulling me up a hill in 4th, when as the revs dropped it started to whine very loudly. Soon as I built up more momentum I changed to 5th and it whined again until I had some more revs.

Whats causing the whining. It often makes a quiet whine but never this loud. Is it the fuel pump?

Was your Wife / girlfriend / or both of them in the car at the time?

You will need to diagnose the whining by a process of elimination.

It's up to you which one you eliminate first.

A wife and a girlfriend in the landy at the same time, now there's a recipe for trouble.

I was on my own at the time, so I can rule out the girlfriend. I don't think she could make such a high pitch noise as this.

Just been told by a friend that it could mean a couple of things,

1: Fuel pump on it's last legs
2: Fuel filter in need of replacing, blocked making pump work harder.

I'll change the filter if it continues. Although I believed the pump was at the rear somewhere? I don't really know, this was definately an under the bonnet noise.

sometimes under similar situations mine makes a whine a bit like a kazoo but higher pitched. And sometimes a tat-tat-tat noise like someone blowing intermittently on a comb and paper - been like this since new and dealership couldn't find a problem butsuggested it was looking to start a band...

When did you last change your rotary oil filter.
Also if its coming from the front check your turbo blades too.

lots to check......fan belt, power steering fluid, oil pump centre bolt, alternator bearings, could b a leak in the intake piping after the turbo.....

just been fully serviced, so yes new rotary oil filter.

get a small groan at low speeds from power steering, but i know it's not this mainly because I wasn't turning the wheel.

reckon I can rule out the fan belt as it wasn't a squeal more a "whine"

as for the other suggestions, thanks, I'll get checking.

another thing to check, although how ya check it stationary or on the roed is beyond me, is yer viscous fan. have heard of the odd one playin up.

Would transmission fluid make a difference

Just found this on an older thread,

I did a search first, promise!!! (just maybe didn't try hard enough)

.... suggested a defective fuel filter could be the issue so I replaced it yesterday with a new one and the pump is absolutely SILENT! So the filter was the issue....

I think changing the filter might be first on my list of things to try, although being serviced recently I would have thought it would have been done.

Thanks for all the advice!!!

Go to the rear right wheel arch where the fuel filter is.

It either looks NEW (just serviced?) or they didn't change it.

My TD5 makes a nasty noise when the filter needs changed, even ticking over and parked.

So, which END of the car is the nosie coming from?

It's all covered in mud by now!!!

I just worked out what the noise is!! uve trapped ur dogs tail in the door!!!!
