Not that strange - it is the later HP pumps which cause the noise, the earlier ones didn't have the problem.

Can anyone confirm the "older" model number to be 0445010011 ?

Mark2000cc · 12th September 2012, 08:54

Hi guys really sorry to drag a old thread up but i have this exact noise and its driving me mad,to the point of me not liking the car very much because of it,does anyone have a definitive answer to the problem and would anyone be able to fix it for me,i am prepared to travel any distance because i love the car apart from this.
And is it a expensive fix because money is tight at the minute.
Any help would be brilliant.

Its pointless to even worry about it let alone spend money on it.

When I noticed it I with mine I initially thought it was the alternator bearings or something mechanical.

After doing the standard test thanks to Jules.. (turn the engine off and see if it disappears instantly) I just accepted that it makes that noise but runs totally fine.

Its not really that intrusive to be honest!

Mark2000cc · 12th September 2012, 09:13

I understand what you are saying but i think it depends on how loud the noise is,and on my car its very loud! If it was quieter i could put up with it.

Is all your sound deadening in place? On the bulkhead and under the bonnet?

Is the Engine cover on?

As far as I can work out, you either have to replace the HP pump or a valve on the side of the HP pump, and to me, it seems like a lot of hassle for nothing.

If it aint broke don't try and fix it!

I think if it was that easy, everyone would have done it by now instead of just living with it.

I'm one of the most OCD people I know, and I've managed to just accept it, definitely cheaper that way!

I could understand your concerns more if it was the flagship V8/260 model, but lets be honest, the diesels are more of a utility car.

Mark2000cc · 12th September 2012, 09:26

Yes my cover is on and the deadening is in the correct place,to be honest i dont understand your comment about its only a diesel,at the end of the day its still my car wether its a v8 or a cdti,i still sit in it on a daily basis,i still drive it just as a v8 owner would drive theres

and wether its a utility car or not i would love a fix for it.However if it is really expensive and a major faff i guess i will have to turn the radio up a few notches!

Cheers.

I heard it/ noticed it within days of getting mine. Not that prominent. I no longer hear it, unless I am particularly listening for it.

No one seems to have found a fix for it, but it is generally assumed to be a gasket or a valve vibrating in the later model HP pump. Swapping the pump for the earlier model from a scapper is suggested to fix the noise. None of the Mk I diesels seemed to suffer the noise.

I'm lucky, or not so depending how you look at it. My pump was defective and leaking diesel. It had the whistle too. I replaced mine with a second hand unit from a 2002 car. I only did it because it was leaking though. To put it in perspective mine was £200 to fit + the cost of a second hand unit. I was still ********* it though as I didnt know if the second user pump would work or not. Fortunately for me it did and now my leak + whistle has gone. Im happy but out of pocket.

Would I spend that kind of dough and go through the same stress just to clear the noise? Answer nope!

It is worth fixing if the only thing spoiling the car is the whine!
Afterall it's a one off payment.
