Fuel Consumption 2.2 Hdi / Manual

[Randombloke]

I'm wondering what sort of fuel consumption 2.2 HDi owners are getting?

 

Mine is a 5 speed, 136 Bhp 02 2.2.

 

I get between 35 and 43 mpg, taken off the trip computer but verified by checking tank to tank mileage v amount of fuel needed for a refill.

 

The car has 70,000 miles on the clock.

 

The figures are with the car clean, not towing nor with anything on the roof.

 

I find that to get over 40mpg I must stay below 75mph / 120km/h. I've been driving it in France, before you ask about speeding. Best figure of 42/43 mpg obtained with a mixture of 50 mph on dual carriageways and 70 mph on the motorway.

 

The car has cruise control which I use in the absence of crowded roads.

Have you had the Diesel Particle filter replaced in the exhaust system?.....if it becomes blocked, wich it will do you will loose performance wich will increase the fuel used.

Checked with Pete Simpson at Mid Kent Citroen using the RPN number and the filter isn't due a change for a while. I'll check with him again at 72,000 miles as this is when some older cars needed a DPF change.

 

Have you any figures for what people get in real life with this car/engine combo? I'd asked and been told 35 to 42 wasn't too bad......

Same engine but 6 speed (able to use 6th above 45ish mph). On 21k miles.

 

To work and back with quite a bit of queuing, 7½ miles in 20 to 30 mins, gives about 42 mpg.

On motorways in summer about 50 to 53 mpg but with queues can drop to about 48 mpg this time of year. Towing the caravan gives about 30 to 32 mpg keeping to about 55 mph on motorways.

 

Last week did Warrington to Hull on M62, gave 50 mpg going and 46 return so average 48 mpg. Going about 30 mins and return 45 mins of queues at Manchester and Leeds. Stuck to speed limits where possible but averaged 38 mph over the 230 miles from the car computer.

 

These figures have been constant over last 6k miles and confirmed near enough when filling up. The computer is reset every few weeks. Do not have an agressive driving style which can waste fuel. Do not bother with the cruise control.

 

So if it is the particle filter that is causing your poor fuel economy then it has a pay back in sorting it. Also worthwhile looking in your handbook for the expected fuel consumption figures.

If your vehicle has an RP No of less than 9491 (Nov 2002) it should be replaced every 50,000 miles. If yours is due i wouldnt rush out and get it done untill all the bells whistles and flashing lights come on.....unless you want to go spend loadsa money!

Would an over-adjusted handbrake affect fuel consumption?

yes :lol: , so would incorrectly inflated tyres ......but i'm assuming from the start of the post that some basic homework has been done.

[shallishanti?]

Yes, sorry.....was just looking at my 2.0 HDi and the handbrake was way over adjusted. Might help explain why I'm only getting 40ish to the gallon.

My RPN is 10511 and in fact the change is due at 72,000 miles.

 

Seeing as I intend to go off into Europe for a big tour this summer I'll do it and take the hit. I've already been quoted and booked in for 72k service.

 

I had to tour France last year in a Merc with a limitation due to the brake pads being changed and the OBD not having been reset - the damn car was rev limited. So, I'll simply burn the cash and forget it for another 72k miles. Usually I get rid of cars between 160 and 180k. This one may go at 130.

 

I'd hate to have to limp home or do without the car for a few days if away on hols.

 

@ kfk Thanks very much for taking time to post advice, it's much appreciated.

 

@ other posters:

 

All other checks have been done. The car was checked immediately after purchase for dragging brakes, handbrake adjustment and the tyres are always checked and if not would nag me via the valve sensors if low pressure.

 

I'm thinking that air filter and DPF change should have a + ve effect.

 

Just out of interest, have their been any air mass flow sensor problems on C5s? I know there has been an issue on Audis, and IIRC they also use Bosch sensors.

Some slight improvement in fuel economy after the DPF change. That improvement is despite doing the distance at a higher average speed.

 

Will report back after a long trip this weekend.

[Randombloke]

Improvement is better than I thought.

 

Getting 41.5 to 43 on trip computer checked by tank to tank manual calculations at 70-80 mph, mostly French motorway driving. This over about 1,300 miles.

 

Sh*te old C5 seems to be going well.

 

Had up to 47 on a half tank that involved a lot of dual carriageway driving between 50 and 65 mph.

 

Town and hilly, slow countryside is still rubbish, but not done much of that.

 

I'm now going to say that seems that for reliability and economy, plus avoiding DPF costs the 6 speed Mk 2 C5 2.2 (post 2004) is the one to go for if you want a 2.2.

 

As has been said elsewhere if economy is your no 1 priority, then choose a smaller engine. But the combination of power and the Hydractive 3+ has me convinced.....

[Randombloke]

Extra note on fuel consumption - a roof rack plus hang glider is causing between 3 and 5 mpg damage to the car fuel economy. Probably similar to a roof box, as the blockage ratios are about the same.

[72dudes]

Definitely sounds a bit low. My 2001 51 2.2HDi SX manual has done 51k miles, I've had it for 12 months and carried out brim to brim fuel consumption checks every time I fill up (as I do for all my cars - wifes, company cars when I've had them....).

 

My average over the year is 44.2 MPG (government combined figure was 44.1 for this model!). I do have a fairly gentle driving style, I tend to cruise at around 75 MPH on long motorway journeys.

 

The lowest individual tankfull was 40.1, the highest was earlier this month at 50.7.

 

I find the computer is around 5% optimistic.

 

For interest this 44.2 average figure is fairly consistent with other cars I've had over the last few years:

Volvo V50 2.0D SE - 45.3 MPG

Peugeot 407 SW 1.6 HDi - 45.9 MPG (but a bit underpowered)

Rover 75 CDTi (131) - 44.8MPG

Volvo S60 2.4 D5 SE - 43.5 MPG

 

but as these were company cars I was covering larger distances with more motorway work, which makes the C5's figure all the more impressive. I'm very happy with the economy, comfort, driving experience and looks. I wish the electronics were less unpredictable and "gremliny" though!

 

Cheers.

Hi just had my fab and eloys done here in Franc 551euros one stud was rusted solid. proper price 444 euros citroen gararge quote 300 euros for one tyre speedy 440inc for two Bry

I typically average about 45mpg, if I cruise at 60 rather than 70 for long journeys I can easily get this up to 50mpg (both on trip and from brim to brim - not a lot in it).

 

I can just (in summer) get 50mpg to work and back (16 mile round trip) if I am very careful and avoid rush hour.

[Guest Chilie]

Oh dear - I fear mine is the worst yet. I was getting 31 MPG from my 2.2HDI which has done 52k. Have had the DPF and eloys done this week OOUCCHH! £375!!! Its a bit too early to say how much its improved as I have only done 50 miles since. I have also fixed the dragging rear brake this weekend so will see what the combined improvement is and let you know. Im thinking there must be something wrong somewhere but i havent found it yet. Still I do spend a lot of time in standing traffic which doesent help.
