2002 172 - picked up, knock- 1st gear

[Jackson172]

When stationary, put foot on clutch and into 1st gear to pull away-

about 6 out of 10 times you hear a knock under the car/engine as it slides into 1st gear (happens in no other gears)

think i can feel the sound through the clutch pedal too slightly? If you put it in 1st really really slow...no knock

but its slightly annoying as I havent a clue what it is?

 

[chappers849]

you have described the same problem as i have got exactly. I would also be interested if anyone has any ideas what this is as my car is booked into the dealer on the 5th for this?

 

[16v_jon]

bottom dog bone engine mount needs replacing, take a lot of stress and only has rubber bushes. a new one is £31 or you can replace the bushes with powerflex poly items for £30 .

 

[chappers849]

thanks for the info, is this something you have experienced with your car and by replacing the bottom engine mount cure it? Should i mention this to the Renault dealer?

 

[Jackson172]

Mine has 6th months main dealer warranty, as bought from renault - guessing they should replace it.

Just a pain in the ass to book it in etc/time of work.

How does the bottom engine mount make the "knock" when going into 1st? Happens with no other gears, only when stationary etc.

is annoying! thanks for the help

i thought it was just one of the 172 'quirks' mines always done it, think you'll be hard pushed to find one that doesn't to be honest

 

[LegoHead]

mine does it too, everyone's does and there are loads of ppl with different solutions. I launched in first and the knocking was so bad that it jumped out of first gear!

 

[Gaz_]

i just live with it!

 

[Jackson172]

great thats exactly what i wanted to hear! all this talk of engine mounts got me worried.

car is on 52 plate, engine mounts going would be worrying!


So just to clear it up

1) Sat at traffic lights
2) Lights go green so put foot on clutch
3) Select 1st gear, as you slide it in you hear a "knock" from the engine/under car area
4) Pull away all ok

(does not happen everytime...but happens alot!)

 

[Gaz_]

yep, to a tee!, well mins a 52 plate and has just had a replacement steering rack work that one out, my warrenty runs out on the 30th, thank god they changed it, the part was 300 + vat without labour!

*Update*

Car is at dealers today for the above mentioned problem and they phoned me to say that they think it is something from the clutch area. Problem is that they want me to authorise for the cost of repair because they say that the gearbox needs to be stripped down to see if the problem is the clutch or to see if in fact it is something else which is covered under warranty that is causing the problem! Thing is unless i authorise then they won't strip it down to find out exactly what is the problem so it is kind of a gamble. Do i authorise them to do the work and hope that they find something else which is covered under warranty and then Renault will foot the bill or do i authorise it and end up paying for a new clutch which i don't think is the problem as car is not slipping in the gears and gears are not difficult to select.
Cost of work which includes a new clutch comes to £860 from a dealer.

Has anyone got any advice for me as it would be appreciated.
thanks

 

[portal172]

If it was the clutch, it should do it in all gears....

Tell them to replace the mounts, if it's not that, atleast you can elimate them from the equation, and they don't cost a fortune.

 

[Guy]

sometimes if i press clutch down, and just as its knocked into first, you can feel the engine jerk a bit. like the clutch isnt releasing 100%


is my clutch on its way out??


ive also got a knocking when lifting off throttle at like 10mph, which i think is an engine mount - thats going to be fixed on friday at dealer

 

[Loopz]

hm...i get a similar knocking noise when i floor mine in 1th gear...it kicks in at about 4k revs and gets stronger when it reaches the limiter...

the odd thing is, it only does in 1th gear and only when i go full throtle...if i take it up to 7000 gently in doesn't occur...


anything related?

 

[chappers849]

how can i prove that the clutch is fine and not worn out or faulty like the stealership is claiming!?

 

[ben_p]

^^ put it in 5th at 30 n boot it, if it slips then its on its way out,

with knocking when pulling off, they u can just adjust the bottom mount, see the guide at the top of this section, its worked for me!

 

[chappers849]

have finally got my car back from the dealers as did not authorise for the expensive work to be carried out!!

I put it into 5th gear at 30mph and put my foot down hard on the gas and the speed and revs came up together like i would expect it to do. The revs did not shoot up which would indicate a slipping clutch!
Also i can not get the car to make the clunk if i select 2nd gear, only seems to clunk in first like the original problem.
The dealer has said that the clutch is slightly dragging, does this make sense to anyone and does anyone know if this would cause the 1st gear clunk problem??
Has anyone got any other ideas on what the problem could be and would the bottom mount adjusment do anything??

thanks in advance

 

[Gaz_]

trust me they ll do it, well the ones i've been in!

 

[RenaultSport]

trust me they ll do it, well the ones i've been in!

Same here!

 

[Macca172]

Mine's a 2002 and clunks every now and then when selecting 1st, I notice it even more after a track day thrashing! It doesn't really bother me though, just character of the car I suppose!

 

[Gaz_]

^ yup, nothing to worry about mate

 

[GazCB]

But why dos it do it? WHY?!!! I ask you goddamnit! No other cars do it. Why is acceptable for a 172 to do it? It happens in my car exactly as described in the first few posts, when engaging 1st in a stationary position.

 

[Gareth]

mine does it, doesn't bother me though. FFS its hardly the end of the world as we know it.

Sounds familliar..mines more of a clunk sound

TBH @ around 15k I would be really shocked if it's the dogbone bushes....I've come to the conclusion that it's a common trait of the 172/182 and so I just ignore it.

 

[GazCB]

Cos if you look past your nose and you decide you want to sell it. Take a potential buyer for test drive:

them - "what's that clunk?"
you - "oh that, it's a characteristic, they all do it, it's nothing to worry about "
them - "yeah right, I'm off :dapprove: "

^bump^

 

[chappers849]

has anyone had the same problem since this was first posted or does anyone know of a fix yet??
thanks

That sounds like your tyres spinning and trying to regain grip mate

 

[chappers849]

any updates to this problem??
regards

 

[Cup ov Ste 53]

Mine does it (bought at 13k) always has. If the gearbox shafts are stationary when selecting first it clunks in. Live with it................

 

[Martin_172]

my 1.2 16v done this, replaced the bottom dogbone mount with a 2.0 172 one and its sorted.

 

[Neil G]

i thought it was just one of the 172 'quirks' mines always done it, think you'll be hard pushed to find one that doesn't to be honest

Yep....I though it was just a Renault thing as well.

Mine does exactly the same

 

[Dan 172]

Mine doesn't do it.

I know Chappers849 has had a new gearbox and 2 x clutches and his still does it and his car is the same age as mine.

I would want it fixed if mine did that, as it's got to be doing damaged in the long term?

 

[shakee]

Mine had the exact same noise when selecting first, then on fri evening was in traffic on the m3 on my way to bournemouth i pulled away in 1st lost drive and heard a crunch, was the thrust bearing on the clutch!! Phoning round 2day and renault want £840!!! for a new clutch to supply and fit, cant believe it.

 

[Dan 172]

Try a RenTech if your down that way instead of Renault.

Most Renault specialist will charge alot less.

I think a garage in Bristol quoted £550 for a new clutch.

 

[ChrisE]

If u can drive it properly then it wont do that...

its only if u floor it split seconds before u lift the clutch!!

 

[shakee]

Def didnt floor it, was only in crawling traffic!!!

Thanks dan is there a Ren Tech in the south east?, (car is at home now!!)

 

[Si172cup]

I get this also...first gear only.

I do wonder like someone who mentioned this earlier it can't be good to hear the engine/gearbox hitting something else!

 

[fastwunz]

It so has to be engine mounts and nothing else - mine did this all the time when i had my valver - replaced mounts - end of problem.

Do you drive the car hard? i only ask becasue ordinarily the mounts would last a bit longer than you indicate

 

[sneeks]

My car has done this since I bought it earlier this year. I don't even notice anymore.
