Scenic MPG
I have just done an mpg check on my Scenic and i am not too happy. I filled the tank then drove 447.4 miles from Manchester to Marlow and back and
filled the tank again, 51.79 litres. That works out at 39.24 mpg 
The obc said 38mpg.
I used to get 50+mpg from my peugeot 405.
I have owned the Scenic for 7 months now and it has always felt a little sluggish so i have cleaned out the egr valve and the hole it fits into as
best i can and the it feels like a different car now and i have just drove 20 miles on the motorway and the obc says 46mpg.
I am going to Derby at the weekend so i will check the mpg again and report back.
Loving the new Grand scenic.

If the car now feels different then there is a good chance that it will improve mpg as well.

To be honest, I would have thought that around the 40mpg mark would be about right as they are a
fairly big car. However, have you fixed that hole in the tank yet? Perhaps that is part of the cause?

That does sound a bit low. The overall average for my Astra (last 10,000 miles) is 38.4 mpg !

You could be right.
There are quite a few complaints about the mpg of the dCi engine on the renault forum, some dCi engines return low mpg and others are ok. Strange.

Sorry to butt in, but I've just recently bought a scenic, so I'm interested. What scenic are you driving? The avatar looks like a pre-2003 one,
but what do I know?
Mine had only 33 mpg on the OBC when we got it (25 miles) but now after nearly 400 (none motorway) it's gone up to 47.8 mpg - I have never reset it
as I intended to do that when we refuel, and it's still on the first tankful!

There are at least two variants of the 1.5dCi in the current range, 85 and 106 - is that the bhp?
Questions, questions. I hope your mpg improves soon.

Update
Well the Scenics mpg hasn't improved any.
I've cleaned the egr valve and the maf and serviced it and this has drastically improved the performance.
The obc says it's doing 38mpg around town and a brim to brim tankful confirms this. since we moved it's only doing short journeys and rarely gets
warmed up fully so i'm happy with 38mpg.
I've just done 400 miles, 300 of which were on the motorway at 70-75mph the obc says 39.5mpg and i've just filled it up to the brim with 47 litres
so that works out at 38.6mpg which i am not happy with as i was expecting around 43mpg on a motorway run 
I think i've got a decision to make in the new year, sell it and buy another peugeot or just live with it.

Does it still have its original MAF [mass airflow sensor?]as i understand the car could be over 4 years old? then its quite possible the sensor is not
functioning like it was intended to do.
This will mess up your fuelling and cost you 3 or 4 mpg easily.

As far as i'm aware, yes it's still the original maf.
All work up until about 85k is documented in the service history and it's not listed as having the maf replaced but i've no service history between
85k and 106k as the previous owner didn't keep a record.
Is the maf a dealer part or can they be bought elsewhere/cheaper?

before rushing out and buying an MAF, try unplugging it, if the car[don't worry about a rough tick over] runs a lot worse, without the MAF then I
wouldn't bother buying one just yet. If it runs about the same or the running actually improves then its past its best and thing will get worse.
There is a way to test it,properly, but the car needs to be plugged into a workshop computer,and more importantly you need a proper auto electrician
who actually knows what the volt reading should be, not just the coffee boy checking for fault codes.
As this would cost you £50 at least and hopefully the MAF could be under £100, its not really worth doing.
I said hopefully as they seem to vary in price from £65 to plus £200 depending, on who makes the car.
Hoping you find that missing MPG, but do remember were are no into the colder months and cars tend to use a little more fuel on shorter based trips

I have replaced the maf and cleaned the egr valve again and the last tankful returned 33mpg
The trouble is that the car is mostly running cold as most journeys are less than 5 miles, so it doesn't get warmed up properly.
I went to look at a 307 1.4hdi yesterday, unfortunately it was sold when i got there but the dealer seemed more intereted in mine than i was in
anything else he had for sale, he said he'd never had a car come in for px that looked so clean and shiny. He offered me £1600 px. £300 depreciation
in 13 months is not bad.
He's got a 307 2.0 hdi in that i fancy but is it worth me spending £1200 to change my car? I think for 30 miles a week i drive and the 4 trips to
Devon a year, the 1.4 would be a better buy.

Can't comment on the proposed change to a Pug, don't know much about them. But on your fuel consumption it is probably the short journeys that's
ruining the fuel economy. When I run my car on mainly short local journeys I tend to get the mid 30's, if I can get a long motoway journey in the
middle of a tankful it goes up to the low/mid 40's and that's for a 3 litre  Yours does sound as though it is on the low side though unless you are doing a lot of grand prix style starts at traffic lights.

JLP, which engine in the 307 were you offered?
I have experience of the 2.0 110 HDI and i know someone who owned the 2.0 90 HDI so may be able to help if you are interested?

I don't have any experience of the 1.4, but i would think it would feel a little under powered in a 307 as they are quite heavy and the 90 struggled
a bit.
My experience of the 90 is that they had a common issue with fuel pumps dissintergating and pumping iron filings around the fuel system, resulting in
over £2,000 worth of repairs.
If it was done under warranty it should be OK as the car i know that had this issue is now running fine, and the problem never returned.
Always wrong.

Been to see this Peugeot 307 today, this dealer also offered me £1600 for the scenic, love the 307 but it seems over priced for a 2001.
I'm going to see a couple of Ford Focus's tomorrow.

Thats identical to the 307 my ex drives, only her's is a 53 plate.
She loves it and says its cheaper to run the her last car, a 206 HDI 110 with the newer 1.6 16 valve engine.
The rapier spec isn't too bad, its the same spec i had on mine but i had the 110 version.
They are quite well spec'd as standard with 6 airbags, ABS, ESP and EBD which have all worked hard and saved me at some point in the past.
I reckon you could knock a few hundred off the asking price if you look for others and show the dealer some prices of the same sort of age and
mileage.
Always wrong.

Watch out for the hateful dual-mass flywheel on it and the 307's do tend to have slightly more than their fair share of French electrical gremlins
.... Nice to drive though.

Been to see 52 plate Focus 1.8 TDCi Ghia today, 105k, full service history, recent cambelt, 6 months warranty, 12 months mot, £2295. Seems cheap??
They offered me £1500 for the scenic, is it worth me spending £800 to change my car though? Is the mpg going to that much better on a 307 or focus to
be worth while spending the £800?

Been to see this 206 SW 2.0 HDi 90 this morning. Drives ok, it has full
service history but not by a peugeot dealer, it has a sticker that says the timing belt was changed recently but theres no paper work to prove it.
It's more than i wanted to pay for a car but it's a bit newer and is lower mileage than the other cars i've looked at.
I don't think the 2.0 HDi 90 has a dual mass flywheel, can anyone confirm this???? I know the 2.0 HDi 90 in the picasso doesn't but the 110 does.

I don't knnow about a DMF in the 90, but my 110 had one replaced under warranty so i can confirm that they do.
If the belt was changed recently it should look in good condition, so have a look to see what condition its in.
If it looks worse for wear, or you can't decide either way, don't bother with it.
