Audi a6 c7 2.0 tdi manual. -Clutch issue.

[fak]

Hi. My car broke down, the clutch pedal was stuck to the floor, the cylinder had failed, I managed to ram the gearbox into first gear, then drove in 1st gear further along the road for about 15 seconds to park up, did doing that harm anything? There was also a metal knock noise underneath the car while I was doing that. Thanks

Hi I doubt its done any damage but if you have to do that put the car in first then start it, if the slave cylinder inside the gearbox is gone most likely that the master cylinder will need to be replaced as well as the pedal going to the floor will have overrun the seals on the master cylinder.

And any idea what that knocking noise could be? It only started after it broke down, its like a single metal knock noise every half a second while I drove it.

Hi probably the release bearing on the slave cylinder as it has no hydraulic pressure to keep it in place, its probably knackered which is why its noisy, how many miles has the clutch done.

The car is on 170k, I bought the car at 140k, I've no idea when the clutch was last changed. Clutch and flywheel is 1500 frm tps, I'm hoping to avoid that lol

[fak]

My mechanic says flywheel needs doing as well, but I listened 2 the car engine, there's no unusual engine noise at all. Is it possible for a faulty flywheel to not give engine rattling noise?

Hello Fakher, 

It would be false economy not to replace the flywheel at the mileage of you car, when the clutch is replaced. It wouldn’t surprise me if you mechanic were to say they wouldn’t  replace the clutch without replacing the flywheel 
Kind regards,

Gareth.

The cylinder inside the gearbox has failed, can it affect the clutch or flywheel? My mechanic says just the flywheel is faulty, the clutch is fine but both needs replacing.

In view of the amount of dismantling involved, it would not make sense to just renew the release bearing assembly. But it’s your and your mechanic’s choice.

Hi if the slave cylinder gives out it sprays the clutch pressure plate and driven plate with clutch fluid, it would be financial suicide to just replace the flywheel as the whole clutch wears as a set so you would have a driven plate and pressure plate with no definitive milage trying to bed in on a new flywheel, the flywheel alone is over £500 and if the old clutch kills the new flywheel that is money down the drain, its a major strip down and apart from the clutch kit you will need a new driveshaft and radial shaft seals

Just done mine clutch was fine but with all work involved everything was changed.

 

£1100 in total 

[fak]

So where did you get the parts from? And what was all the parts exactly? Can you individual price for each part? Thanks. 

[a6blacked007]

Parts all in £750 luk 

 

Labour mammoth job £350 

 

Flywheel Alone £500 .. 

 

The £350 Labour is a good price for the job you'll find some garages putting massive price in because don't want to do the job.

 

 

my advice replace the lot

[fak]

So £250 for clutch kit? Does that include release bearing? And concentric slave cylinder? Was it from dealers?

Hello Fakher,

I think it’s time for you to do your homework.

LUK is a prime brand, so I would go with that. There are cheaper alternatives, but I wouldn’t fit them.

LUK should do a kit which will include the release bearing/ concentric slave cylinder - same thing. 
Suggest you search eBay and/or other factors such as Car Parts in Motion - there are more.

Perhaps you could let us know how you get on.

Kind regards,

Gareth.

Depends what you buy.

 

The flywheel and clutch come as complete unit just to bolt on if you but luk kit slave cylinder comes with it.

You don't want miss match parts in there thats for sure it's not a regular clutch replacement very different sort of setup my mechanic told me.

Hi the slave and bearing are all one piece the slave is about £100 on eBay, genuine part, then you will need the seal that goes in the middle of it, Mark is right its nothing like any other car I have worked on as the driveshaft runs in the middle of the flywheel edge so when you remove the driveshaft you have to replace that seal as well and to remove the old seal you have to remove the diff housing as the seal is fitted inside that, yes its a monumental task I didn't do mine but the guy that did it is a friend and I was there for nine hours on cleaning and tea detail so I saw the whole process including when the clutch master cylinder wouldn't pressure up, if you buy these cars there are a good few items that aint cheap but shopping around gets it cheaper, like my mates MK2 Escort clutch £140 but for anything later those days are long gone.
