Well the air filter for my brothers megane finally arrived today. £9 delivered from ebay for a genuine Renault filter.
Details of his car: Megane1 2001(51) 1.6 16v K4M.

The only tool you will need to do this job is a T25 screwdriver. Oh an maybe a chicken cup a soup as its cold out there at this time of year.

Ok so the first thing to do is identify the air filter housing. From the picture you can see a large plastic box with a white label on it, I presume this is just to quieten the sound of the air being taken in. this needs to be removed to get at the filter housing. Its secured by a little rubber clip at the front, but its fallen off in this case.



Once its removed you can clearly see the filter housing.



The filter housing is held in place by 2x T25 torx screws.



Once these are removed the filter housing will seperate from the engine with a little wiggling about.



The housing is quite hard to remove from its location because of the size of it, a little bit of fiddling and its out.
As you can see in the next pic, the filter was very dirty on my brothers car compared with a nice new one.



there is nothing difficult about replacing the new filter and the housing, just a simple reverse of what has been done so far.
On the black box that fits onto the housing, there is a rubber seal around the end of it, this can be a little tricky to fit back on.



As the air intake pipe on my brothers car was no longer in one piece i used some 'duct' or 'duck' as some may call it to fix it.



This is a very simple job to do, takes around 15mins to complete. Almost seems silly to make a post on it but I hope its useful to someone on the forum.

Excellent post Stef especially for beginners. Good clear pics as well.
Looking at the pics a new bit of flexi inatke pipe wouldn't go amiss. It would do no harm to clean up the master cylinder and its cap just in case the breather hole gets blocked.
I expect he should be able to get better mpg as well.

Well done:d

first of all thanks for the positive feedback guys, also thank you for nominating me for TOTW.

madnoel, I will try and source a new intake pipe but the old one will need to do for the tim being im afraid. I've done what I can for now. Next time I get the chance I will give the master cylinder and its cap a clean, thanks for bringing that point up.
Just got to get a fuel filter and an oil filter/oil to complete the service.

This post is better than you think stef as it would cover the Laguna 11 as well, your pictures and descriptions are more or less exactly the same as for my Lag 11.

The large plastic box is the "air box" this is designed very carefully to iron out the intake pulses from the engine so the air flows freely more than to suppress noise.

So you get another nomination from me.

nice one stef, bit of a ¤¤¤ about getting the housing back into place as its a funny shape, being wider at the bottom with no room to move it :rolleyes:, but should be of great help to beginners.

thanks daft plonk, yep it definetly is a bit fiddly. getting it out was what held me back the most, that plastic pipe that comes out just infront of it cant make it any more akward! if it wasnt for that it would have taken 5 mins max.

Nice little post from mad man:d

This will also help members with the 2.0 16v espace F4R engine as its the same set up as mines but the only difference is you don't get to see any of this:crazy:and you have to work blind so it will give espace owners something to look at before taking the job on and help locating screws and the like about the bay:d

Cheers Donald

Cheers geez ... dunno why but airboxes have always been surprisingly tricky in the cars I've owned and the manuals/haynes have been no help - took one look under the bonnet this time and was just :confused::confused: so no difference there. (Polo - excessive number of little snap-clips holding on the 'dustbin lid', and at least one guaranteed to skin your knuckles ... the less said about the Astra one being pretty much wedged in the drivers side wing and requiring a steam hammer to move it into an accessible position and then open/close it the better)

Hopefully with this advice it'll go a little easier and less painfully than it otherwise would. :d

even though its my first post on this forum, just wanted to thank you.

I have shown the registration paper of the car to the guy at the market and he gave me wrong one, the one which looks like a circle, but I do have to go again to exchange it this gonna be when they open on monday (long time)

any way after I opened it it looked similler to your filter though.

Haha, you said you reckoned it was such a small job and not deserved of a How To post but you were wrong Stef. Helped me out no end pal as I thought, just like everyone else me thinks, that the black resonance box was where the filter was housed :rolleyes:

I too, have broken the stupiodo fibre pipe in two places trying to get to the filter.....gaffa tape here we come :rofl:

ha, well i will take my comment back - i obviously didnt realise how helpful such a simple post could be:eek:

glad to be of help:) i wish someone in my family still owned a renault, im getting bored at the weekends:rofl: although not a renault, i will be doing track rod ends soon and i think one of them looks a bit stubborn so might make for a good how to post.

yeah gaffa tape is the business:d

The hose on mine had also fell to pieces, this set up is identical to my 1.4.
Trying to source a replacement was a nightmare due to its ''oval'' profile, i've recently learnt the hose is not available on its own but a complete assembly eg; air box, collector & hose, repairing mine i know why, the hose is stapled to the air box!
I made a satisfactory repair by removing the staples & the hose that was damaged, cutting the top & bottom off a stout plastic bottle & cutting down the middle. it was then wrapped around the air box & taped up, some sealing compound was needed as there are proud ridges on the air box.

Just adding a further "thank you" on this, as it DID turn out most useful. Done this twice so far and it was an ¤¤¤¤ on both occasions! Like yours (stef) my intake pipe is now more gaffer than original (I could replace it with a generic halfrauds tinfoil one, but I've seen those unwind at an alarming rate before - i reckon a couple of tiny vacuum leaks drawing air from the engine bay to the filter won't matter), and now I've got the added, sexy, concours-winning bonus of the airbox itself being sealed up by it.

Yep, those damn torx screws and their stupid location / inability to be completely removed. One of them is almost completely drilled out, and impossible to put back in place without a little cross-threading with the tools I had, so I've left it standing a little proud (it'll still stop the box from falling out completely and the filter unsealing) and secured the box fully in position with the other one and half a roll of tape, as the only thing on there it would stick to was itself.
Note to self: Next time I have to do this, fully clean and de-grease the outside of the airbox before re-assembling, or at least remove whatever alien-technology coating was preventing even duct tape from sticking. Also use a mini-ratchet with a high quality torx bit, and maybe make use of some glazier's putty to try and restore some kind of screwability to the bolt head, given that it can't be removed. That or find a scrap housing cover that, somehow, hasn't got ruined bolts.

What is it with Renault and using Torx bolts in completely unsuitable places? I've had to replace all the pencil coil securing bolts with hex-heads as well, as I damn near couldn't get the original ones out after the first go and certainly didn't fancy screwing them back in a second time... (plus it was the devil's own job keeping hold of them whilst inserting or removing... one disappeared off into manifold land for a while and was only later found having been shaken out onto the driveway by the bump of the kerb)

Guys, my first post and thanks to Stef. Read loads on here as I am stuck in France (and I don't speak the lingo that well at all yet) and so having to repair and service my second hand (french) Scenic I (Ph2). We bought the Scenic as we needed the space for my new baby daughter and a 2nd car to work out travel to nursery and wifes work etc. I bought the air and pollen filters a couple of weeks ago and been trying to find time to fit them, then sat working my way through the forums (already used to sort out my stuttering engine - ignition coils) - to find out where and how they go, both were fited within 20 mins.
The ignition coils took me 45 mins, (excluding time in the garage - see below) and cost me £52 incl shipping from the UK (for the set). Overall you guys have saved me about 700 euros, the garage wanted 480 to supply and fit the coils and another 250 to investigate and correct the cabin smell, he pobviously knew what it was from what my wife tanslated.

Next job... fix the cabin heater thermostat.. on full only.. seen the post.. taking out the dash top to find the resistor pack this weekend.

I'm a computer geek by trade, swore I'd never get my hands dirty with my car, might as well have shown me a knitting pattern .. always traded comouter fixes for car fixes... but having some (frustrating) fun and a great sense of achievment doing it myself now!

Anyway enough rambling on... big thanks and chin ups to everyone. Superb help.

Cheers :D !!!!

bobbydog: nice fix, going to have to sort mine out a bit better as it has all the wrappings of a manic mummy currently!

tahrey: hear you on those torx screws and the ignigtion coils.. nightmare.. and I'm 189 euros lighter as the local garage had to be involved to drill out two of them for me. (I have a nice set of torx drivers and bits ... now!)

Recently I attempted to change my filter. Took the old one out no problems. However I struggled to put the casing back in, there is hardly any room to work with. After about 10 min of fiddling I managed to screw it back in. Went for a test drive and couldn't stop noticing my wee 1.4 sounding like a turbo. The casing was not put back in properly and it kept making this deep noise when over 2.5k RPM.
It took me another 15 min to put it back properly.
