Whit the focus it make's a diffrence but i think it's because you go from 16 to 18.
Whit the mondeo if it have the standart 17 and then to 18 it's not so a big diffrence.

Brian · 13-12-2009, 08:23 PM

Mine had 16" as standard

Brian

TIFF · 13-12-2009, 09:44 PM

what mpg are people getting out of there mondeo TDCi's then......

I see around 34mpg with town driving only....always thought it to be a little low tbh

Brian · 13-12-2009, 09:47 PM

Around town 45mpg and motorway 53mpg thats doing 70mph

Tiff did you clean just the EGR valve or inlet as well? have you fitted a new fuel filter and air filter might make it better mate

Brian

TIFF · 13-12-2009, 10:09 PM

i just cleaned the EGR

Will do the inlet in the week if its not too fiddly......And the fuel filter/air filter......see how its goes

7xrskb · 13-12-2009, 10:26 PM

Don't know if one available for the Mondy tdci but I fitted an egr bypass pipe on my Vdub and blanked of the pipe from the exhaust. Stops crap from the exhaust clogging up the inlet side of things.

Brian

Brian,

worth doing as there was a lot in there.

i got a very thin flat head screwdriver to get in and push the release part of it,did the trick, its hard to get at it and get it off the normal way.

dave cos4x4 · 13-12-2009, 11:01 PM

very easy to do the fuel filter aswell, 3 push on fittings to get off,pull the filter out, fill it up,slot in,plug the pipes back on.

Yeah, you can get them on ebay for a couple of quid. I've got one waiting to go on!

TIFF · 14-12-2009, 05:47 PM

Does it not affect the performance by blocking it off???

st3v3 · 14-12-2009, 06:43 PM

No Tiff it shouldnt affect the performance, by blanking off what you are doing is taking some of the fumes from the burnt fuel and stopping them entering the engine to be reburnt again, so efectively only letting in outside normal air now instead a mix of air and fumes,be aware though, if you have the electrical connector on the EGR and you blank it off, the ecu *MIGHT* read a resticted air flow and put on the engine managment light, How ever some people have had no problems at all with this, some have.

TIFF · 14-12-2009, 07:36 PM

I dont have the electric connector on mne........

Is it just a case of putting a plate over the pipe then??

st3v3 · 14-12-2009, 07:50 PM

you want this mate: http://cgi.ebay.co.uk/mondeo-tdci-td...item414b08a9a8

and im sure you can work out where on the EGR it goes.

dave cos4x4 · 14-12-2009, 09:08 PM

so that just fits in the middle,sandwiched in.

what is the benifits in fitting it?

st3v3 · 14-12-2009, 09:14 PM

pretty much as in my post #52 also it stops the EGR and inlet getting all shited up with Carbon.

dave cos4x4 · 14-12-2009, 09:21 PM

suppose its worth the £3.50 then lol.

st3v3 · 14-12-2009, 09:25 PM

its worth the £3.50 just so you dont lose the MPG decrease as the EGR and Inlet get clogged up,you'll probably save £3.50 in the first month.

rsmat · 14-12-2009, 09:53 PM

im going to do mine tomorrow...TOP INFO GUYS!

TIFF · 14-12-2009, 10:07 PM

Plate ordered.........got to be worth the £3.50.......lol

Will clean out the inlet while im at it me thinks.......is it easy enough to do??

dave cos4x4 · 14-12-2009, 10:41 PM

got mine ordered too.

Mark,

easy enough, once the egr is off and the multi clip on the inlet,thats a bit fidly lol, then 9 bolts on the inlet and its off.

i cleaned the ports on the head too, these were clogged up too.

scrapped them out then got a small brass wire brush, seemed to get most of it out.

TIFF · 15-12-2009, 08:33 PM

Cheers Dave....will give it a go at the weekend..........Fuel filter and air filter on order too...

Will look at ordering that blanking plate aswell i think

Where's the best/cheapest place to buy the fuel filter?

Brian

dave cos4x4 · 15-12-2009, 11:13 PM

Brian,

i gor a bosch one off ebay for about £12 all in iirc.

re mpg, keep an eye on the temp gauge. when upto temp it should sit dead central and hardly ever move. theres a valve on the back of the waterpump which plays up, it's only about £10 and this creates too much flow around the systems when it breaks so the engine never gets upto temp!

Right so is that why my TDCI temp gague has been sodding about recently then?

If it is ill get one ordered and fitted after work along with an egr clean

Markt8 · 17-12-2009, 02:03 PM

Hey guys i had an ex police 54 plate TDCI 115bhp on 115k Miles ran mint but only ever seen about 34mpg around town and i never bothered with it as the mondeo owners club said it was normal.

I recently got a 02 plate Ghia x 130 Bhp TDCI showing 140k Miles, ran great but the mpg was ridiculous at a lowly 29mpg around town. First thing i done was service it, new oil, oil filter, air filter and fuel filter this has got it up to 34mpg around town, im gonna try this egr cleaning and inlet cleaning as i dont see the previous owners ever doing it as it was owned by a bank 1st then my friends dad who wouldnt even know how to change his own wheel, im dreading what comes out of it but hopefully it knocks the mpg up, is there anything else i could do ive heard cleaning the maf can work and theres a how to on wiki too.

mark

rsmat · 17-12-2009, 04:50 PM

did mine yesterday and its slowly going up...thanx guys.

mark_24v_wiring · 17-12-2009, 05:05 PM

Well i changed the second stat last night and cleaned out the EGR which didnt have a whole lot of crap in it but car seams to be loads better temp sits just bellow half all the time now just got to see about the mpg

TIFF · 17-12-2009, 09:03 PM

what are people getting from a full tank........

I get about 460mile

Brian · 17-12-2009, 09:26 PM

When i used ours every night for work i was getting around 500-550

Brian

Northern Bloke · 17-12-2009, 09:56 PM

600 - 630 over a week which is big motorway run each end of the week (steady away at 80-85 when poss) and round town all week and weekend. It's showing an average of 52.5 mpg at the moment

Mate and i know alot of people are gonna say im talking shite here, but on a steady run ive had over 800 mls to a full tank, i think it was 812 i kid you not!!

i think i get nearer 500+ with both motorway and town driving, if you believe theres an egg under the accelerator and when you come to trafic lights, let off the gas way before, you can really make a big diference.

The only reason i havent gone back to a performance car yet is because of the MPG i get out of my diesel

TIFF · 17-12-2009, 10:17 PM

Steve...........exactly mate.......

My Mondeo looks smart, goes ok...even better soon once remapped and the the MPG is good....Why would i want to fast car......

My car only does short town driving tbh..

R4N S S · 17-12-2009, 11:49 PM

i get over 400 to a tank in my astra and that is on bio fuel

but think i need to clean out the egr as its not as good on fuel as it used to be and i thought it was down to using the veg :Cry:

TIFF · 18-12-2009, 06:24 PM

What a fucking nightmare it was doing the fuel filter........... My mate changed it for me and could we get it to start agin....COULD WE FUCK!!!!!!

Took ages.....

BUT, there was LOADS of shit in the old filter....so hopefully it will be better now.

Brian · 18-12-2009, 08:08 PM

Did you fill the fuel filter first?

Brian

TIFF · 18-12-2009, 08:15 PM

nope.....school boy error
