Hi I am planning to change the clutch on my 2007 a3 tdi s line(140 bhp).Which is the best one to go for ?Also does the flywheel needs to be changed or any other parts with the clutch ?

At the moment only planning for a remap and remove the cat but if the turbo let go one day it will get a hybrid one,together with uprated intercooler and injectors so I need a good clutch so I dont have to change it again.

Thanks for your help

Cheers
 
Jumping in on this how much of a job is chaning he clutch?
Is it a DIY job for someone fairly mechanically minded or strictly a garage job?
What kind of price are you looking at for parts supply only or how much does a garage charge?
Cheers
 
really need it on a 2 poster ramp ,as sub frame needs lowering down ,gearbox off etc wouldnt like to attempt this on a driveway also better to swap flywheel at same time , aprox cost flywheel ,clutch swap £450 depending on which clutch /flywheel it is as theres 2 different ones with a price difference
 
I never had an audi,nor a modern car.I always had fords and still had escort mk 6 rs 2000.Never heard that when changing a clutch one need to change the flywheel,but I am sure I heard it on this forum before.Anyone can tell whats the problem with them ?
 
If the stock clutch ever goes fit an uprated one as it will last the life of the car especially if you intend to remap the car etc. Sachs and Helix are the two main clutch manufactures in England both with very good reputations. The uprated parts are the same design and fit as stock parts so any garage that can change your stock clutch can fit an uprated clutch. Parts to change are the thrust bearings,pressure plate and drive plate. Once removed the flywheel can easily be checked to see if it needs replacing but most garages would want you to replace it as well as it`s extra profit earned. PD140 flywheel is designed differently to the old PD130/150/160 DMF and a lot less prone to fail.
 
I have no problems with being stolen from a garage.I am from malta and my dad's cousin is a good mechanic.He wont be cheating about that.So you are telling that if the flywheel dont have any damage its better to leeve the standard one as they don't fail very often ?Here in malta we have very short distances so think the clutch will get much more abuse.
 
the will know if its damaged straight away the problem with the dual mass flywheels is the rubber centre piece that is filled with grease to absorb vibration , this becomes weak and torn and throws the flywheel off balances causing the vibration and judder felt through the clutch pedal
 
everybody seems to have his own opinoin on BMF or SMF flywheel.The truth is ?Who knows lol but maybe evybody seems to have trouble with the standard Dmf,so only option is either an after market DMF or after market SMF ?I was told that if I use SMF,the clutch need to have springs.Is that right ?
 
If you go SMF the clutch will rattle loadly while in neutral and you need a different designed uprated pressure plate to work with the SMF.
 
The standard oem dm flywheel are rubbish. Ive seen problems with them on rs4 v8. Am using smf at moment and apart from the gearbox chatter noise on idle its perfect! Acceleration is quicker due the lighter weight. Smf is probably more meant to be for highly moded cars for people who can appreciate there function. The average joey on the street would say its sounds like a truck, so i dont botheted explaining and rather say line your crap up lol :)
 
Hehe I dont drive like a nun but dont want my audi to sound like a truck while in traffic.The thing that worried me most is that people are saying they damaged their gearbox because they used SMF.I was also told that the diff in a3 gearbox is a weak point so def not good putting more stress to it.Afterall the factory dont DMF for a reason,said to be to take gearbox vibrations,so if AN SMF is used,something else will take the vibrations ?Right ?My mate in a bmw 530 changed to SMF but he is running over 400 bhp and dont have any noise even when idle,maybe because its a petrol or rwd ?

Can I buy any aftermarket DMF flywheel and clutch kit and will they hold more power as the SMF do ?For know I am going to remap it but a bigger turbo,intercooler and injectors will come soon when funds allow.

Also if I find my original flywheel in good condition what do you suggest me to do change t while the box it out or risk it as it might have a life ?Mine is 2007 s line 140 bhp.

Sorry for writing an essay but really confuesd on what to do and dont want to waste money on this car too.

cheers
 
Diesel engines vibrate a lot more then petrol which is why they rattle a lot loader then petrol cars with a SMF. A SMF only rattles when the car is in neutral with your foot off the clutch. If you intend to go mad and go hybrid turbo with uprated injectors ( i have a spare set of P1287+ uprated injectors fitted to some stock injector bodies if your interested ) then you might as well go for a SMF as there is no such thing as an uprated DMF unfortunately. Don`t go to low weight with the SMF as lower the weight more noise and vibration it will cause and stay away from aluminim flywheels as they don`t last on high torque diesels and are known to cause loads of problems unless your car is used for races and want to strip it down constantanly. If you are going to fit a hybrid turbo and injectors you need to think what power but more importantly what max torque you intend to make and fit a clutch that can handle the power as a 400lb torque clutch will be no good to you. I have a Spec stage 3 + clutch with SMF which is rated at 590lb torque which is a very good clutch and drives much like the stock clutch.
 
dont want to go so mad mate,its a daily driver but want something like 220/230 bhp and some good torqueto keep me happy during week days lol.Not aure if I can reach that figure with the standard turbo.
 
You will not make 220-230 on a standard turbo.
 
That's what I weas thinking.Will look about that later.At the moment I am only concerned about the clutch,de-cat and re-map.Will an aftermarket DMF cope with 220/230 bhp ?
 
I had a stock DMF running on my car for three years with it running 330 bhp and 490lb torque with no problems. Only changed it in the en because the original uprated clutch started to slip and there are no 600lb clutches i knbow of which work with a DMF.
 
so you are saing I can get away with the standard flywheel ?
 
If your intended power range is 220-230 bhp and 360ish lb torque then yes i would stick with the standard DMF.
