hello,just got my dci sport tourer "A" serviced@ 90000 miles,so far so good,as i,m on night shift, dealer picks up and returns car from house while i get mucho needed zzzz,s £152 all in .(was £170)
Anyhow on signing for return of car and driving it for first time ,the clutch pedal was right down to the floor(if it had a cable ,it was if it was snapped) and a very STRANGE and NEW ticking noise from engine/gearbox/clutch,i hooked my toe end around the underside of pedal and it sprung back to original and normal posistion AND noise dissapears ,.
My Q's is could this have caused any damage ,should i inform dealer,the car had only done 10 miles on way back from garage

Hi All,

also having the pedal to the floor issue, only it's not intermittent like some reports on this thread.

I had the car towed to my trusted local garage and they tell me it's the slave cylinder.

Interestingly, I had a new clutch (and slave cylinder) fitted over Christmas by another garage so I am talking with them about getting it replaced under warranty.

Am I correct in understanding that I shouldn't have to pay the labour charge to get this fixed? I'm worried that the original garage will say that the part is covered but that I will need to pay the labour costs. That isn't right is it?

Many thanks in advance,
Craig.

Quick update after talking with the garage that did the clutch in December. They confirmed that the parts supplier will cover the cost of labour and supply the new parts.

I suddenly feel way less stressed :)

Of course, there's still a chance for it to bite me in the behind but I'm more hopeful now.

Will let you know the final outcome.

It was the slave cylinder. Thankfully all repaired under warranty/guarantee.

While the box was out the garage noticed oil leaking from the drive shaft boot (gearbox oil leaking) so that got replaced (at my expense). Glad they found that!

Quick question, the new clutch biting point is right near the floor, is there a way to adjust it or is that normal?

Thanks,
Craig.

Hi everyone,
I seem to be having the same clutch pedal problem as most of you. The car has had this fault ever since i bought it Five years ago but hasn't got any worse, However as i am selling it i thought i should do something about it!
So far i have only changed the brake fluid and bleed the complete system including the clutch side due to me changing the brake discs and pads, however this didn't work (Clutch system shares the brake resovoir).
I have now decided to go with the next cheapest option which is to fit one of those pedal springs everyone is talking about. I called Renault and they said my 1.9Dci wasn't on the recall list in 2006 and that he hadn't even heard of the fault! This i found hard to believe so i ordered a chlutch pedal spring (which is in the catalogue for my model) anyway. It's part number is 7701473045 and it cost me £3.85. I would put a picture of it on here but i am having trouble putting it on (If someone can tell me how then i will). Basically it has an overall length of 84mm with it's spring being 48mm long. On the ends there are plastic locators which are different at each end.
Now for the killer question!

HOW ON EARTH DO YOU FIT THE THING

Quick update guys,
Right, i have seen where this clutch spring is fitted but it looks as if it assists in the pushing down of the pedal and not the return of it. So to that end i might have bought the wrong spring, however i fitted it anyway just in case they have made the new ones weaker to allow for the pedal to return easier. As you can see the new spring that i fitted is yellow and the one i removed was bare, so i don't know whether there is any meaning to it.
It doesn't take long at all (Took me about 10mins).
I pulled the retaining clip out from the clutch pedal side of the felt under panel and just twisted it out of the way to allow for better access.
Now for the fiddly bit, with one hand pushing the clutch pedal to the floor and the other hand using a screwdriver to gently prise the botton of the spring out of its recess, you can then use your third hand to push the bottom end of the spring up further into the cabin compartment. This allows you the room to remove the top end and let the spring to drop out to the floor.
To fit the new one first locate the top end of the spring then again with clutch pedal down use a screwdriver to prise the bottom of the spring back into its recess.
Replace felt under panel.
Job done!
Now i don't know yet if this has fixed the fault as i might have just fitted and explained to you guys how to fit a spring that has nothing to do with the fault!!
But hey, lets hope its all is good.

Be extremely cautious changing SLAVE CYLINDER. I've done this, but it was small nightmare, just because I've found out proper manual AFTER, not BEFORE such repair :0

There are 3 (THREE) different SLAVE CYLINDERs for the same Lagunas (year, engine etc). I visited Renault to explain this, but they "explained" looking at brought new cylinder: "it's 3rd party vendors matter", lol, which apparently looks like explanation of man who just wants to be clever. Just wants, and not is. If 3rd party vendors manufactured incompatible parts, 2/3 of them wouldn't fit repaired cars, and original wiring must fit 3rd party product sockets. It was wasting my time, unprofessional people.

All you need to do - is to REMOVE cylinder first, take it with you and compare in store, that's it. Otherwise you'll end up with opening the gearbox too many times. Cylinders have a bit different shapes, some of them are auto-vented, some have manual vents.

It's good idea to change CLUTCH at the same time (and gearbox fluid, as I remember it costs about 12,50 per liter in Renault) and you need 3-4 bottles, depending on gearbox type.
