Dephaser

[k1ano]

My understanding is that the de-phaser, as it's name suggests, adjusts the phasing of the cam shafts hydraulically based on a signal from the ECU. I would imagine the worst that can happen with a faulyt one is that the variable valve timing isn't as effective as it could be.

IIRC a Renault tech told me a few years ago a bit of noise is quite common, especially on start up when the oil has not warmed up.

Classic symtms is cold start up rattle. This normally ceases with first blip of gas.
Not a major problem, but something id always wanted to address..
Further deteriation would be a continual rattle. Clio 182's can suffer from this..

But as Scott says, there are many cars out there that just live with it..

James - do hope your on to something there? Ill ask paul at RPD to check in to it..

Note, I'd replaced the solenoids first thinking that may solve it..before ordering the pulley's over a year ago..

Good description but i think its the initial rattle that bugs everyone. the cams dont advance until over 3k anyway so perfectly drivable provided the rattle is not constant, if the rattle is there all the time catch the bus. even if there does not seem to be a problem if one breaks up you could have a big bill if any of the metal bits find their way into the motor.
Its also nice to see that reno are / were overcharging yet again.

I bet that if its shared part with other makes then it's mabufactured by one company eg Bosch - then it would be even cheaper to source but someone needs to check an old one taken off to find out

My v6 has developed a loud rattle on start up, again like others have said it goes after a blip of the throttle. I cant live with, it drives me nuts! Currently talking to Scott at SGM to see what can be done. My car has done over 50k miles, is this an inevitable problem as cars pile on more mileage or are lower mileage more pampered vees also affected?

Please lets us all know what Scott has to say about it and if there's a fix, as it appears more and more Vee's have this problem as they get older :rollseyes:

 

[pirateBOB]

Yes, will keep everyone update with developments

 

[PeteH]

Scott is doing my car very soon to fix the problem. At present only Peugeot can supply the part, as posts above.

 

[matt.v10]

I hope to send my car in to Scott over the next couple of months for a reasonable amount of work/ upgrades and I'm stalling while a solution is found.

Not looking forward to paying for those Peugeot dephasers, I may jump on the band wagon and start contacting Renault.

Should Renault want to help find a solution or provide the parts at a sensible price or is it no longer their problem considering the cars age?

I guess Pete knows the most about what's going on, do you think it would be helpful if others wrote to Renault for 'advice' ? If so have you any names/ email addresses of the people who know what's going on?

Thanks

:approve:

Everyone's starting point should be to order the Renault Dephaser pulleys from their chosen dealer. In my case RPD.

Then once 'back order or no part available' is confirmed, you then need to contact Renault customer services and open a case..

I did this back in October 2013!

Id be interested to hear what feedback people get from RCS..

for everyones info, I and Renault have looked in to numerous solutions and im afraid the ONLY solution is at present Peugoet parts.

I have written to the new MD, Jeremy Townsend and others...to get to this point, alot of time, calls and letters!

Renault sport division had also been contacted..basically I created a BIG issue for Renault UK and France..

And YES Renault CS will play the 'age' card! You will have to fight your corner..

I could discuss for ages! but if anyone would like further advice happy to talk 07805 495204

GOOD LUCK!

I have the same issue. Massive rattle for a couple of seconds in cold start... Mine is getting close to 40k miles now.

I don't see this clear. Is this just a matter of annoying noise when starting? Or is it something much more serious that could lead to a broken engine and a huge bill?

 

[EEE007]

These pulleys must be able to be reconditioned ,maybe using parts from 182/197 etc , has anyone got a broken one , as I have friends in engineering who could look at this and it wouldn't be a damn site cheaper than the new ones available

 

[PeteH]

When mine are changed, I will happily leave them with Scott at SGM for anyone to check or use for reconditioning..
I would say that over the course of all investigations, reconditioning was never proposed by Renault, SGM or others..
Also remember its engine out, so you want to be sure its a A1 solution..

May be a trick I missed! Hope so for everyones sake!

Very interesting, thanks :approve:

 

[PeteH]

Wow, alot of info!

Could anyone explain if this changes our current situation?

I wonder if the Peugeot part will be improved over the original Ren part?? - locking pin??

 

[EEE007]

I don't think it changes the situation but it is ammunition to throw at Renault to at least put pressure on them to supply parts and maybe cheaply as a goodwill gesture.

Yes I saw that a couple of week ago whilst also researching but didn't think to post as a lot of the links seemed to be not working. But there certainly are a lot of other de-phaser articles out there indicating the common issues and under-engineering of the de-phasers etc.

Food for thought ...

Anyone?

 

[EEE007]

Well if the dephaser completely broke up inside and jammed it could break cambelt and damage valve train / Pistons etc..
