Hi

I've always had a little 'dink' noise when moving off from a standstill, particularly in reverse, sometimes forward, around half a second after I move off. It has never caused an issue or got any worse over about 40k miles, and I've never really known if it was normal or not.

I've just been reading a thread about similar and Haldex low oil was the cause. I also read in another thread that pulling fuse FB6 will disable the Haldex.

So not knowing anything about Haldex's, my thought process is that disabling it may help identify/troubleshoot the cause.

So my question is, is it that simple? Will the Haldex simply shut down? What effect would this have on the drive of the car? Is it safe to do so? Anything I should know?

Thanks.. .

I wouldn't disable the fuse as you will get a fault warning hdc fault. I would recommend having the haldex oil and filter replaced as it quietened mine. My unit was so low on oil that it would freewheel whilst turning at junctions resulting in a sort of grinding noise.

Thanks. I only meant disable it to eliminate or confirm that the Haldex was the cause of the noise obviously. But it's due a service shortly so will get it done regardless.

I have a problem: when the steering is in the end position (bottom right or bottom left) the rear axle jerks and it worry me.
I removed the fuse as you say but the problems persists.
I removed it for your same aim, understand if haldex is working or not.

Please note that no errors was showed in the display.

So I quote your question.

What effect I have to aspect pulling the fb8 fuse.

At last someone else showing up with the DINK. Was my first post and had this from day one and demanded it be sorted, still there ! Its beyond LR to deal with it but it could be as simple as the brake pads moving or a spline that needs locktite. I just live with it now.

Rear Axle changed at one week and Haldex has had the "Bell" treatment this year. FL2 MY10 TD4 GS traded in at 2 years

Actually I had a PM from someone last week with the same, who was also off to Bell to try and sort it.

I still haven't had my haldex serviced, on account that the oil was changed when I had work on the diff 2 years ago, and the oil still looks pristine. But I was wondering if the levels were slightly out or the refilling procedure hadn't been followed correctly. (Or if it was just my central locking all along )

I'm sure it's not my brake pads. If it is it's continued through a pad change. It feels and sounds like something mechanical engaging.

continuing in my research I would like to have a simple information.

the test condition is the following
  removed the famous fuse and placing the car on a hydraulic bridge with all 4 wheels free and the first gear with the engine off.
which it is the correct behavior of the rear axle trying to turn the wheels manually?

Front transfer box?

The bearings can fail, can give a knock for a long time before it finally gives up the ghost.
on mine the input shaft splines failed - the slop in these will give a clunk as drive is taken up.
taking the prop shaft off is a good way of isolating the unit, disabling the haldex might work.

Also front drive shaft splines can wear. Tangiers Orange - gone, missing her

To be fair I asked Austen at Bell to just service my Haldex not look for the rear Ding.

So I look forward to someone telling me what it is but don't bother if its expensive to sort

Mine has the electronic hand brake and that may be the culprit releasing. FL2 MY10 TD4 GS traded in at 2 years

I have the dreaded 'clink' which is probably the same as the 'ding' and the 'dink' !

It occurs about 1 wheel revolution after moving off forwards (I always reverse into parking spaces) and after 1 wheel revolution when reversing i.e. it always occurs after a change in direction.

It is nothing to do with handbrake shoes as it occurs after parking without the handbrake and when reversing after a journey.
It is nothing to do with the pads moving in the calipers as I have tested for that too.

I emailed Bell's, as I read it could be to do with the engagement / disengagement of the Haldex, but got no response.

I have checked, with weight on the wheels, for problems with suspension bushes but cannot find anything loose.

I have checked the rear drive shafts and cannot replicate the noise there.

I have checked the diff oil, which was a little low, and am going to replace that this weekend.

I would like to get it sorted at some point ! FL2 HSE Auto Galway Green

Andy - to be honest it sounds like it's behind the driver in the middle of the car, but obviously it's very hard to tell.

YorkyBob - manual handbrake here, so can probably eliminate that.

Pedro - totally agree with the 1 wheel revolution description on change between reverse and drive... which is why it's strange, as whatever needs to engage to drive the car has already happened. Please report back on diff oil change

Yes de1979, it was me who PMd you last week.

Reporting back as requested

Changed the Diff oil a couple of weeks back and have still got the 'clink' / 'Dink'.

I am now gearing up to remove the Haldex and clean / service it over Christmas as my Christmas present to myself

I will report back on the outcome in a month or so. FL2 HSE Auto Galway Green

Nice one. As I say my Haldex oil was changed, but you can never be sure the refilling procedure was followed properly! Looking forward to hearing back...
