The topics below all have one thing in common. They all report and discuss the same FAULT! Yes a FAULT that has never been rectified by Land Rover. If you have a S/C or 2007 onward TDV6/TDV8 HSE, then your car is fitted with DYNAMIC RESPONSE and is likely to develop a knocking noise which sounds like 'water pipe hammer knocks' coming from the area of the front suspension. If this is the case, then your car has a FAULT with the DYNAMIC RESPONSE system and, if like the high number of owners below, your dealer can't/won't fix it, then at least insist your dealer reports this 'water pipe hammer knock' noise to Land Rover as a FAULT, using an Electronic Product Quality Report or EPQ Report. STRENGTH IN NUMBERS.

Mine has this knock thru the ARC system also. Still in dealer, they have changed the steering column and have also shown me the LR bullitin regarding knocking thru the dynamic response and have said that it is normal. There is no fix as this is how it works apparently. The noise is the hydralic valves. The bullitin states at 20 mph rock the steering and a knock will be heard left to right.

The following is a quoted from an earlier post by Nutty Nige and contains a test to positively identify whether the Dynamic Response 'KNOCKING FAULT' is present in your RRSport or whether a different fault is the cause of the knocking.



"I think we all need to be aware of all types of noises that are present at the minute so as not to get confused. The loud grinding noise heard when turning on full lock when cold is normally the steering lock stops and it normally does it when the suspension is still in entry mode. Any chattering noise or un-even feel in the steering can be the steering column or the lower column joints, on any slight vibration or wheel wobble you might need the modified rack mentioned above. The Dynamic Response knock that is called Characteristic is defined by driving at around 20mph on smooth tarmac, then snatch the steering wheel one way then the other- the harder you turn the stering wheel the louder the knock. Then switch the vehicle off remove the battery cover and you will find a long fuse box next to the battery. Remove the fuse box cover - 2 rows of fuses on the right hand side as you look from the front of the vehicle and a lot of relays on the left. The row of fuses that are nearest to the relays and furthest from the wing, count back from the windscreen end including the fuses and the empty slots to the 5th fuse you will find it is 15amp. Pull this fuse out and close the bonnet. Start the vehicle, you will notice the red light on the dash a picture of a car with 2 arrows above it, this means the DR system is no longer active. Now carry out the same test at 20mph, You will find when you snatch the wheel the noise has gone. Stop the vehicle and replace the 15amp fuse. Replace the fuse box cover and the battery cover. Start the vehicle up and you will notice the light has extinguished- carry out the test again- the noise has returned. This is the characteristic noise mentioned in the technical service bulletin. I hope this helps."

I have a 2006 MY SC registered a month ago - I noticed this problem at low speed and was v concerned (as the same system had problems sending a water pipe type tapping through the brake pedal on delivery, which necessitated a software update).

I subsequently noticed the steering knock, took the car in to my dealer's service center and then took two LR engineers out to replicate the problem - FYI it seems much less pronounced with more weight in the car.They did know what I was talking even though it was happening in a watered down fashion.They also claimed that it was partly the result of steel ball joints as well as the electronic stability etc. I was also told it is "normal".

They then put the car on a hoist and checked the tightness of all the front suspension and steering joints - if you haven't ever looked underneath your sport you should - the way the rear transmission is mounted to the chassis looks like it is designed to withstand a nuke, and the chassis members look incredibly strong - basically the vehicle is seriously engineered whth what appears to be significant reserves of excess strength and torsional rigidity - vv impressive!

The vehicle was then plugged into the electronic diagnostic equipment to check the electronic suspension etc - it measures a whole series of values/parameters to make sure everything is within the required tolerances.

Perhaps this is commonly known but in case any of you haven't owners should see this test - the car dances around going back to front, side to side, corner to corner etc as the suspension is articulated. It looks a bit like one of those LA lowriders with trick remote controllable suspension. While I am not 100% satisfied, seeing this and watching the thorough way in which they went over the car meant that I left feeling more confident in the vehicle's integrity. Then I read this part of the website.................

I really love this car, but hope it doesn't let me down. Time will tell.

Any further advice on this problem would be much appreciated.

Problem

if it were a charateristic of the car then mine should have the knock too - but it doesn't - said this before but it sounds like an assembly or components tolerance issue to me

Kaine,

Perhaps you should offer yours to LR and ask why you haven't got this characteristic

Guys - this thread should be joined by the admin police to the other (larger) one on the same topic - despite all this/these emails/qns there is no answer/realistic response from the manufacturer...................

Think of the amount of money the people on this website have spent on these cars.


V disappointing - moreso having read some of your (the collective members') posts on the topic

Burn them ALL and in doing so liberate yourselfs from the knock...


...then buy a TDV8 Vogue

Must be time for direct action!

Mine was looked at again recently, it has come back even worse! Not only has the tailgate rattle re-appeared after they replaced the plastic molded shroud on the locking mechanism - it had fallen off and was rolling around the boot space.

I reckon that they may now have disconnected the DR as mine now handles like an upside down jelly mold on acid!

If you are thinking of buying a RR Sport, read this forum very carefully first !

If your DR has been disconnected or the fuse has blown you will get a warning light on the drivers binnacle.

You must be driving your vehicle really hard if you think the handling has changed so dramatically. Normal day to day driving conditions shouldn't really have any effect on handling performance between vehicles with or without Dynamic Response.

I do drive my RRS hard on occasions.

I have just returned from the south of France having recently traveled about 1200 miles the car does feel different for some reason - less sure footed, more body roll on the chassis etc. I have no indication on the binicle so maybe its somethings else.

I have told LR that I would welcome a test drive by one of their "experts" in an attempt to find out why my baby is sooooo poorly

I am new to the forum, and have recently placed my order for RRS TDV8 HSE which I have been promised will arrive by end of September !

Reading through the "KNOCKING" issue raised in this forum I am very concerned !

Does anyone have the latest update on this issue ?

Is there any way that I can get some assurance from the dealer that if this problem arises they will provide me with a replacement vehicle until they resolve the problem ?

Peter mentioned that we should contact LR or TopGear maybe we could have some kind of electronic vote/email petition which could be sent to the relevant people at LR ?

Forum admin is there a way to do this ? Does anyone know who would be the correct person/s to contact in LR so that this issue is taken seriously and resolved ?

Man this thing sounds crazy.. there are a lot of people who have spent atleast 50k each on these vehicles and LR needs to do something about it.
