M1tch's daily 1.5 Dci 80

[m1tch1987]

Hi all,

I have just put a deposit down on an '03 mk2 Dci 80 for my daily drive, I was looking at getting a 65 but went with the 80 due to the fact its got an intercooler as standard and better injectors etc.

I am picking up the car on Saturday and am really looking forward to it, the car seems pretty straight with everything on it sorted, it does have the glowplug/electrical light intermittently flashing. After researching a bit I have found that its either a bit of water in the diesel filter, EGR clogging or the throttle sensor. All of which are easy to sort out, I will be giving the car a good service and check everything over, I will be changing all of the filters as well as taking the EGR out and giving that a clean. The car is also very low on fuel so that might also be compounding the issue, hopefully its not an injector etc but the rest of the car is solid and has been well maintained and is stock.

The car has an upgraded head unit, AC, electric sunroof, electric windows and looks quite smart, I will only be going a few things to it as its my daily drive - I also have a 2.0 HDI Xsara Picasso which my flatmate and I will be tweaking a bit more!

I have spare intercoolers so might look at uprating those, I have actually found a stock Renault Megane 1.9 intercooler is actually quite beefy although far too large for the 1.5dci turbo!

I will get some photos up of the car soon but here are a few things I plan to do:

Good service
EGR clean
Replace the dipstick (plastic end has snapped)
Colour coding a few exterior parts
Perhaps lowering at some point

Its my daily drive so I just want to get everything sorted and running well for getting to and from work (doing around 350 miles a week on the 95% motorway driving).

I have already learnt a lot from this forum and researching which is why I went for a 80 rather than the 65 or 100, should be good for economy, I am actually amazed that the redline isn't at 4-5k like most diesels!

 

[DaylePemberton]

Look forward to seeing some pics of this! There's a few DCI's on here should have a look through the threads and get some inspiration

 

[m1tch1987]

Thanks I do like diesels and diesel tuning, I have found that a mildly remapped diesel with a better throttle response gives better MPG overally, I would only be looking to do a few minor subtle things on the car, standard alloys look pretty good.

 

[GrahamS]

I think you need to make it a replica

Coil looking light can be egr valve, map sensor but can also be signs of diesel pump and injector failure.

 

[RenMatt]

The clio doesn't have a water detector on so wont be that ,The megane intercooler is the same through out the range so 19 dci intercooler is the same as 1.5 and the megane 80 bhp is the same engine & turbo as the clio so if you can cram it in it will be ok &65 & 80 injectors are exactly the same its the 100 that's different .

 

[m1tch1987]

Thanks for that, I know that the injector pump and injectors can fail, I am hoping it is just either EGR or the accelerator pedal sensor, its not on 100% of the time, only under certain conditions which makes me think it might be EGR (as I know that isn't open all the time).

Thanks for the heads up on the intercooler, are you sure its 100% the same as the standard one is massive lol

I will also be looking into a remap or a tuning box - I have had a good results from using basic tuning boxes on previous diesels (not the petrol sort as they won't work, but the diesel ones work well) - my 2.0hdi Picasso is currently doing around 65mpg owing to the extra low end torque from the box.

 

[m1tch1987]

Here is a photo of the car at the moment (from the for sale advert) they have removed the advert so this is the only photo I have at the moment until I pick it up on Saturday!

Planning to colour code the bump strips and look at lowering it about 40mm, might also colour the alloys in graphite gray sort of colour but I do like the stock alloys.

Your one will look something like my old one I used to own when you colour code it .
They look so much better with that done to it .

Good luck with the "Mod"ing and a quick question ?
Aren't those Dci 100 alloys on the one your getting.

Oh and a quick pic of my best MPG .

Great little cars

 

[m1tch1987]

Yeah I will be colour coding the bump strips and the black plastic on the bumpers, will be doing it little by little, I like the subtle mods as they all add up to a nice difference.

I don't think those are the DCI100 alloys, I think those have a raised bit down the centre of each spoke, my car is the 'Privilege' trim, so its got air con etc etc, just 1 down from top spec, so I guess these might be specific to that trim level - everything else is 100% stock apart from the CD player.

Thanks for the MPG reading, its the reason why I got the car really, I am currently driving a very low 1.6 MX5, need something more comfortable. I also have a Xsara Picasso 2.0HDI, currently doing about 65mpg, plans for that are to increase power from the 90bhp it has to around 160 or so.

 

[barnesautos]

My one was a privilege spec -
A/c and all that , roof and auto lights ect.

Not sure about those wheels you have what they are ?
Someone will comment soon enough Mitch.

Little tweaks to the diesels go a long way .

Have you looked at these threads ?

[m1tch1987]

Thanks for those threads, I will have a read, I know that simple tweaks really do help with diesels, will just give everything a good service and clean out and see what that does first.

 

[GrahamS]

They're privilege specific wheels dci100 has the 15" version of the 172 like all ph3s have.

Depends what kind of driving you so but I would expect 50mpg flat out on the motorway and 65 with normal mixed. I had 90 mpg on a trip to reading once. Drove carefully and below 60 the whole way.

There aren't really any performance mods in mine bar decat and intercooler

 

[m1tch1987]

Thanks for that, the Picasso is currently running without a rear backbox, its being silenced by the turbo and cat so its actually still quiet, might look at doing something with the exhaust to free up turbo spool etc which would give me back increased throttle response. Might also look at a remap but need to give everything a check over, might look at getting the cambelt changed and might swap out the high pressure pump as I know those fail and wreck the whole fuel system.

 

[Martin_172]

65 & 80 injectors are exactly the same its the 100 that's different .

the dci 80 and dci 100 share the same injectors. its the dci 65 that's different

Car looks good, lights worry me on them though, usually points to injector or high pressure pump

 

[m1tch1987]

I am going to plug in my ODB2 reader and see what codes come up, the car is on 117k, might just be low on fuel or something simple, budgeting additional £500 for any service parts etc.

 

[RenMatt]

its the dci 80 & 65 that share the same injectors the 100 are different & more expensive

 

[Martin_172]

its the dci 80 & 65 that share the same injectors the 100 are different & more expensive

nope mate other way about, a dci 65 will max its injectors out around 85bhp, dci 80 shares the same injectors as the 100, the turbo holds the dci 80 back.

 

[m1tch1987]

I went with the 80 as I know the injectors are the same as the 100 so there is a larger headroom for fueling tweaks, makes sense as it runs more boost than the 65, am I correct that the 80 turbo is a standard wastegate turbo or is it a VNT?

 

[Martin_172]

Yep 80 is old skool wastegate

 

[Dan@SJM]

Also the 80 injectors are the same as 65's.

 

[m1tch1987]

Yep 80 is old skool wastegate

Good good, VNTs are cool, but I have seen some very coked up VNTs previously so non VNT means less to go wrong!

 

[RenMatt]

Wrong check your facts before you quote ,65 & 80 run the same injectors .these are cheap at £389 a set from ram induction The 100 bhp are £150 each and are exchange . There are more changes than the turbo on a 100 bhp

 

[m1tch1987]

I have now got the car, the garage sorted out the intermittant light, I have just taken the EGR out and the inlet pipe and both are clean and functional - I think the garage might have replaced/cleaned these then reset the light as there is nothing on the dash anymore.

I have also plugged in my code reader and there are no additional codes so it looks like its good!

Just having a check over the engine bay, injectors aren't leaking, glow plugs look pretty new, turbo looks good (eg not leaking!), the inlet manifold is quite coked which is to be expected but I can't clean that, the inlet pipe is clean though.

Looks like the tyres front and back are running different sizes - eg the fronts are running 195s and the rears 185 which is fine as I know that they are the same size but one sort is cheaper lol.

On the way back the car averaged 83mpg, thats town driving to the motorway, needs very very little throttle on the motorway and the gearing seems great - really chuffed!

Car overall looks really good, slight paint issue on the bonnet where I think the clear coat has peeled off, also some cracked plastic around the rear seat drop down buttons (both sides so guessing commong issue).

Overally, really happy with the car, I will get a new fuel filter ordered and might also get some injector cleaner to run through the system but it feels like this car has been really well looked after - lots have been spent on it already it seems (eg service parts and some worn suspension joints).

I saw that the tax was up at the end of the year thinking...great tax soon, but then remembered that it was only £20 a year

I will get some photos up asap, really want to colour code those door strips and it seems that a stone has gone through one of the grill sections - probably a really hard job to replace them due to being French I expect!

 

[m1tch1987]

Here are some photos of it

Engine bay before:

After checking the EGR etc and cleaning it up a bit

Here is an OEM 1.9 Senic front mounted intercooler - might see if its larger than the OEM Clios one, have been told that apparently they are the same size? Anyway, if anyone is looking for a front mounted intercooler, don't bother with an expensive universal one off ebay as the OEM Renault ones are massive!

 

[GrahamS]

Looks great matey. Clean example from what you've posted so far.

people loving the DCis on here at the moment!!

 

[sburrell93]

Looks like a good car you've got there. Rare to see a clean looking pair of headlights! Colour coding makes a world of difference too if you're planning in doing it in future. Well worth it.

That intercooler is wayyyy bigger than any of the clio dci ones by the way lol! The dci 100 one is about half that height.

Also, the upper grille is easy to change on these. Get a sport one on there

You are wrong mate. Different part numbers. Thats why there is more power to be had from fitting 80 injectors before a map.

 

[Dr HMS Derv Destroyer]

i can vouch that the 65's and the 80's are different. ( for the euro 3's that is )

carwoods diesel specialists near me have flow tested a set of 65's and 80's. the 80's flow allot more.
the 100's flow the same as the 80's.

the only reason more power is to be had out of the 100 , is increased fuel pressure and the duty cycle backed off allowing extra performance when mapped.

Ah ok, not really sure if I need to fit something like that, I know that the Fiesta TDCi intercoolers are pretty good as an OEM intercooler, although slightly smaller engine size, I also have a Mitsubishi intercooler off a 3 litre v6 diesel (Think it was from a Pajero) - it was used as a top mount though.

I will keep the stock intercooler at the moment, one of the reasons why I went for an 80 was due to the fact that it did actually have an intercooler and the pipework, so would be easier to uprate if needed.

I will be colour coding things soon, probably also adding some wind deflectors, although first thing on the list is probably the creaking electric sunroof - it seems REALLY odd to have A/C AND a sunroof specced lol

How easy is the upper grill to replace? The current one looks pretty good but will check out the sport ones

The bonnet does also have a paint issue where the clear coat has gone - seems quite specific as if there was a sticker on there but isn't now, anyway I will have a think but might simply spray the bonnet matte black.

If you are looking to uprate the intercooler in future, have a look at AlexW 's dci 172 rep, was linked earlier in this thread. He's fitted a front mount IC using 80 pipework. Biggest cost of doing it is the pipework, needs a few bends to get it all lined up properly.

Lol, yeah, mine has A/C and an electric sunroof! Daft idea, but I think A/C came as an option on these but the sunroof was standard.

Upper grille is just clipped in really. There's two little push clips holding it on at the top, and once they've been removed, it's held in behind the renault badge bit, and a few more clips around bottom edge of the grille. There's a guide on here somewhere but it's pretty simple to remove

Thanks for that I will check it out, I also have a Xsara Picasso 2.0 HDI (90) which doesn't have an intercooler at the moment, and am trying to work out the best routing etc, hence I was happy to find that the 80 had an intercooler!

I will also have a look into the EGR removal and sorting out the inlet manifold, the EGR pipe to intercooler is clean, the actual inlet isn't so I would need to take that off to be able to fully clean it - will decide if that's worth it or not soon.

I will look out for that guide, it looks like that grill has been removed/attempted to be removed before as its missing a few trim clips.

I have also oiled up the bonnet catch a bit to make sure that doesn't get stuck open and fly into the windscreen as I know it can do - need to check if its had its recall etc.

 

[RenMatt]

Best you tell Ram induction that & Renault then

 

[Martin_172]

Best you tell Ram induction that & Renault then

theres no point in getting s**tty about it mate. check the Renault parts catalogue and you will see for yourself.

Delphi part number EJBR01401Z Renault part number 8200132793 - 48KW engine (65bhp)
Delphi part number EJBR01801A Renault part number 8200365186 - 60KW and 74KW (80 and 100bhp)

Anyway, back on topic that 1.9 DCI intercooler looks like the pipework wont be too far away wont require much to fit that!

 

[m1tch1987]

I will have a look at fitting that OEM intercooler - might be a good upgrade at some point although I need to be careful as fitting an intercooler too large will create lag (eg the tiny turbo needs to fill and pressurise a larger volume before positive manifold pressure).

Anyway, that will be a fair amount of time away, just driving it into work, I have cured the creaking electric sunroof using some universal grease on the seal, I am only using a tiny amount of engine power to keep the car rolling on the motorway.

MPG on this tank so far is 73.8mpg - thats 50/50 town driving and motorway, should be able to get much higher than that if 100% motorway - which it will be this week. I have covered probably about 100 miles so far as the fuel needle is still above full.

Looking at the official MPG figure (which is 67mpg) I do wonder how they have managed to only get that as the car is easily capable of much higher mpg considering I got well over 80mpg when I collected it on Saturday.

 

[Martin_172]

I wouldn't worry to much about the intercooler being that size buddy, it doesn't affect it as much as you might think its only if you end up going crazy big with a lot of pipework. I noticed zero difference in lag going from a 65 that has a tiny bend from turbo to inlet to a 80 setup with all the pipework and big intercooler!

 

[m1tch1987]

I have made a decision on what I want to do with the exterior of the car, I plan to colour code the black plastic but will be keeping the OEM non sport grill - the car isn't a sport, might have gone down the sport route if it was the DCi 100.

Will perhaps mock up how the car would look with a colour coded front end - the wing mirrors are already coded as standard, although there is still black around the windows.

The wheels are in good shape but might look at spraying them in a gunmetal gray which I think would suit the blue and then look into lowering the car slightly - say 40mm, just on springs rather than coilovers.

 

[Martin_172]

that's pretty much what I done with mine tidyed it up nicely, I was lucky mine is the same colour of black as a 172 so I just got a set of colourcoded 172 door handles, side strips and spoiler

currently putting it back to standard to sell it on though, my suspension is for sale in the for sale section

 

[m1tch1987]

Thanks for that photo, it looks great, ride height looks fab on that, although my previous car was running lower lol.

I have driven the car for 125 miles or so, its just moved off 'full' its indicating 77mpg - that's about 1/3 town driving the rest being my motorway commute, my previous car was running at around 32-42mpg so burning around 2 gallons of petrol per day on the commute, I have had the car for 1 day and its already saved me a gallon in fuel, plus the saving on the road tax!

Will be interesting to see the MPG once the car is serviced and it has a remap etc, usually see increase of around 20% in mpg due to better throttle response.

I have also just researched into the inlet manifold....ITS PART OF THE CYLINDER HEAD! Why the hell designed that! Arg lol I need to clean out the inlet manifold as its coked up - it would have been how the EGR and EGR pipe would have been before cleaning which is why I think it was throwing a code.

I am still figuring out all of the pipework and how the EGR is connected in the system though, but the throttle response is pretty good on the car at the moment.

Lol! I meant to reply and give you the bad news about that the other day. s**t design by Renault! Personally, unless you plan on removing the cylinder head, I'd advise against trying to decoke the manifold. I wouldn't want all that soot and stuff getting pulled through the engine.

 

[Dr HMS Derv Destroyer]

You can take the cast inlet off , I had a go at machining a k9k head ... The oil/water paths are to close to the inlet ports to make a surface for drill and tapping a proper inlet flange on.

Dont be put off tho, it's not as restrictive as you think. My rebuilt engine with the cylinder head been hot washed , made bugger all different. The hard pipe being clean out tho did!
