Good evening,

I am posting on behalf of my Dad, who is become very irate as he is being sent around in circles by different garages I hope you will be able to help. Here goes the story;

Dad has had the clutch changed on a 2004 Freelander Td4 after completing 131,000 miles.

The clutch was changed but not the flywheel as he was told they are indestructible on the Freelander. And ever since he has had countless trouble:

Firstly when the heater is set to the windscreen and the brakes are applied there is a whirring sound, like when a child has a can in the tire of a bicycle.

Then there is a judder as he pulls away in first or in reverse.

Also when the engine is revved above 2000 rpm there is a metallic jingling sound.

Our normal mechanic seems to think that the problem lies with the clutch that was fitted.

The garage that fitted the clutch believes that it is the VCU at fault and, a transmission specialist believes it could be the flywheel.

Either way there is going to be a hefty bill incurred but could anybody point me in a direction that could fix it please.

it's a dual mass flywheel .. they are potentialy destructable

( i.e. unless someone replaced it with a conventional type )

( google 'dual mass flywheel' .. loads of info about )

no idea what the connection between brakes and demist would be ..
( maybe someone else does )
does the vehicle have AC ?? .. as the AC is activated when 'demist' is selected and fan operated ..
maybe whirring sound is the crankshaft pulley dampener .. on the way out ??

dmf should allways be changed at the same time clutch is ,as its part of the clutch system ,fitting new clutch to old dmf usually shows symptoms quite quickly ,most garages should know this ,or stop working on cars
 
dmf are a dealers con. cars have been fitted with std flywheels for years all cars i come across with dmf i change to std. also why would they make the kits if they cause transmition damage.
 
if they cause transmition damage

in that case .. would have thought damage be down to the way a driver operates the clutch and gears .. .. not all drivers are mechanically sympathetic ..

std will work ,but dmf is much better ,how many damping springs can you fit in a clutch plate compared to a dmf,the extra protects transmission and engine from the harsh torque of modern diesels,apart from its beneficial effect as a heavy flywheel ,its quite well know solid flywheels often have transmission knock at idle with lrs

never had this problem befor they always work for me on lr, skoda, ford ect. never had a problem.

you must be very lucky then ,300tdi commonly had similar transmission knock until clutch was improved by adding better springing,std clutch was at its limit with diesels ,h/d clutch kits often bring that issue back dmf gets rid of it
 
Dmf are a joke should be replaced when clutch done or a single mass one fitted in its place. When I had a Mondeo tdci I fitted a single mass bought the cheapest one and it was no good bought a recommended one and it worked. Dnt no the diff between the 2 other than price maybe the metal but I found the cheap. Ones to be u get what you pay for.

My question do the l series have a dmf

you not sure why they are used then ,as i said before you can get away sometimes without them ,put that doesnt negate the improvement they have over std clutch ,std clutch is ok with an engine running 135 bar injection pressure or tdi at 280 but modern run 1400-1600 bar

he,s correct modern turbo charged diesels have way more torque than older designs and dual mass fly wheels are designed to prolong the life of transmition

What is Dual-Mass Flywheel?
By design, the dual-mass flywheel is to isolate torsional crankshaft spikes created by diesel engine during the overstressing power stroke. Dual mass flywheel separates the mass of the flywheel between the engine and the transmission. By separation, torsional spikes can be isolated and thus eliminating possible damage to the transmission components. But because of many moving components (gears and springs), chances of failure are great. With SMF, dampening takes place at newly designed clutch disc (sprung-hub).

Once my dmf was fitted my Mondeo did 70 tho miles and I never had another fault with clutch and transmission until I sold it se with all the people I no who own transits they all gone to smf flywheel and his is a mini bus with 250 tho miles and other than clutches and drive shaft seals his has being good and the smf flywheel went in at about 50tho miles

I no some people would fit dmf but I'm one who wouldn't and upto now apart from cheap smf I've not had a problem with them in the cars I've had fitted them 2

Can't say I herd that before. All the transit my mate have are there own but are taxis do thousands of miles a year all I can say is if your not sure fit a dmf least the car is how it left factory then

You have to think tho you only normally hear of the worse case like the k series head gasket they all say there really bad and common but there not that bad and there not really that common it's just you only hear of the bad cases

on the subject of your fan in your demister, has something being drop inside down the venting pipes, at the bottom of the windscreen and when you apply the brakes it rolls into the fan , just a possibility hope this helps
