I so recommend this MOD and very easy to carry out.

Heres the polyurethane kit i bought from Awesome GTI click here

and you will require the following bolts (as they are stress bolts)

*N10268302 x 2 REAR

*N90597002 x 1 Front

*N10246603 x 1 Front

* Firstly I Jacked up nearside of the car to gain access to the DOGBONE MOUNT and support on an axle stand. Here is the Dogbone mount.

Posted Image

* Using a trolley jack and an old piece of wood (as a sacrafical material not to damage G/Box) find an appropriate area of the Gearbox to 'support' while removing the DOGBONE Engine mount. Which is held in by 2 x 16mm bolts and 2 x 13mm bolts. [nb DO NOT SUPPORT THE ENGINE USING THE SUMP AS THERE IS A HIGH RISK OF DAMAGING IT.]

Posted Image

*Once you remove the bolts the DOGBONE mount should pull out of the chassis, nb. one of the bolts snapped on me while trying to remove it thus causeing a sleight problem, enough of the threaded portion was still visable so i used the 2 nut method of removing the rest of the bolt.

Posted Image Posted Image

*With the mount in hand there is a long 16mm bolt holding it all together, remove this and your mount should come apart, once apart clean up old grease and muck, and regrease mating parts with grease supplied. Assemble is complete opposite to disassemble.

Posted Image  Posted Image.

*Offer your mount up into the chassis and refit using new stretch bolts, the old ones shouldn't be reused.

Drop car off axle stand and away you go . . . . You will feel like the car has improved throttle response and also has a more positive gear change.

Good writeup. Did mine in a similar way, except I didn't bother supporting it. It will be Ok as long as you don't start the car!


What you didn't say is that all four bolts will need to be replaced - you can't reuse the old ones.

I've just done this in the last half hour and the only difference is I used all the same bolts but the problem i've had is that its very harsh..alot of vibration when i set off unless i rev it highly then you cant feel the judder and vibration..


Hope you can help out budd

@Foolzgold add this too:


Part numbers for the bolts. I don't have the torque values to hand though


+N 102 683 02   X 2   (FRONT)  HEX HEAD BOLT,


+N 905 970 01   X1    (REAR) BOLT


 N 102 466 03    X1    (REAR) BOLT


@ Suni


It is really harsh initally but it beds in. It's quite common to use half of it and half of a regular bush to lessen the vibration.


You need to change the bolts, they are one use stretch ones.

Oh no i chucked the old bush in a tipyard bin..


Im realy not liking it..The way it is at the moment I really dont think im able to bare the judder on it its too violent for my liking, lol


You reckon I should change the bolts or will be okay?
Should i get hold of the old one and use that somehow?

Yes you should change the bolts. You might get lucky but considering what it's bolted to, why take the risk?


I can't remember which half you use when retaining part of the standard bush, but do a search and it will come up.

They are not Load bearing they only stop the engine from rotating . . . Entirely up to you, but i advise you do.

Can be done for less than a few ££ Just buy new bolts and a cheap Lino type floor tile. Just some pieces the same shape as the original rubbers and add on a layer each side. Does a great job without killing the ride

 if this MOD can cause vibration , why not just replace the bush's with oem ones?


 


 


would this work as good and be less harsh ?

It ruins the ride quality 100% . its just another "racer" mod. but by adding "shims" made from a old Lino tile etc you can "dial in" a fraction more feel

would recommend changing the bolts at the same time


 


too many gearboxes with sheared bolts and holes


 


also use copper grease so the broken stuff like up above doesnt happen

Just to update on this I know I fitted the bush kit in March and now its August, absolutley no harshness after 3 thousand miles, and I still think this is the best MOD Ive made on the Car.

 Did you use Powerflex bushes or OEM bushes as powerflex bushes take a while to soften up.

 Everyone recommends only using half the powerflex one and half the oem one for a tdi as the viabration can be bad.

the chances are if you use a new OEM on it will feel a lot better . Or buy new OEM ones and trim off some  then add  lino floor tiles etc to dial in some "feel"

Where is best to get hold of an OEM dogbone bush? Only VW? I have the Red bush at the moment not fitted yet as waiting for the bits to arrive from VW currently. thinking doing half red half OEM. As the standard bush on mine is long gone I think as managed to push a small screw driver into it with no force at all hardly. Seemed more jelly like TBH
