Hi All recently bought a Mercedes e class e280 cdi w211, not happy with fuel economy is something wrong?

Page may contain affiliate links. Please see terms for details.
W211 was never the most economical car in the world. But possibly the best car :)

What you are seeing is only a little on the low side - but not by much. Is it auto?
yes is auto.
 

It doesn't detail the 474 code for DPF,
it does detail 926 Euro 4 Exhaust gas cleaning, others might confirm but I would read that as the Cat.

Hopefully I'm right and you don't have possible DPF complications.

i do very short journeys, going to post office, gym, friends house, etc... all within 1/3 miles area, between 10am to 4pm
since i bought this i have done around 350 miles, which around 150 miles were on motorway and the rest in town.
IMHO, with over 50% being that kind of driving you are not far from optimum. Checking tyre pressures may help a small amount and ensure you are not carrying excessive weight in the boot. You can reset the transmission and it will then "learn" your driving style but not sure if that will help economy -someone will comment
 
Hello Guys,
Bought this car around 6 weeks ago is a 09 plate had 83000 miles only 2 previous owners, last owner had it for 13 years,
Very well maintained by previous owner last full service was done in march.

I'm concern about fuel economy mostly i drive in town short journeys average is 19 miles per gallon,
Please note traffic is not bumper to bumper like in busy cities, my town is 6 miles from Manchester city center.
Also on motorway i have done 50 miles yesterday cruising at 70 / 80mph and it was 35 miles per gallon.
wanted to know if this is normal for its age?

if anyone can help me that would be great,
Thanks in advance.
Hi ,Try an Italian Tune up but get everything hot first.
 
Driving 1 mile? I assume you're of limited mobility. Ice cars aren't designed to to work properly when always cold. How about an EV they're perfect for shorter trips at low speed.

Incidentally, in my petrol v8 i get around 12-16 around town.

If i get on a motorway and zero the trip and do 60ish mph it'll do 30 mpg. But overall its about 21.

It’s the 11 mph that gives it away, on 350 miles, of which 150 were done at motorway speed. That’s a lot of “cold” short distance driving, I’m afraid.

Diesels need to be warmed up to deliver their legendary economy
 
Unfortunately I believe that you have bought the wrong car for your current needs.
 
I would agree that your usage is not what suits a v6 3 litre diesel auto.
It would be worth checking the thermostat - failure (or semi failure) seems to be quite common and does impact fuel economy - it should be running at nearly 90 degrees and staying there - mind you of course your use pattern means it will hardly ever get there.
The other basic things to check are tyre pressures and that brakes are not dragging.
 
You have a nice car, in fact my view is that it takes a lot of beating.
I do realise modern stuff have masses to offer, and I've little understanding.

But it is designed as a cruiser.
Run it for a few hundred miles in a day and it will reward much more than you have experienced.
 
Driving short journeys in cold weather is part of the problem. .
I have an 05 e320 in the US. I've potted around in short journeys and never got under 20 (US} MPG. Sure, take it on a run, but if he's not getting 40mpg (imp), he's got a problem

So no DPF Filter?
( I hope )
One less thing to cause problems.
 
Istr my old S211 (estate version of yours, same 280cdi engine, 7 speed box) at similar overall mileage would do 40mpg ish on a run, but hated slow town driving - got down to about 12mpg once, when doing ten miles or so stop start for someone delivering leaflets.
 
Also on motorway i have done 50 miles yesterday cruising at 70 / 80mph and it was 35 miles per gallon.

It's a heavy car with a 3.0L V6 engine. My guess is that when new it did 40-45 mpg tops at this speed.

Given that the engine now has some carbon deposits on the piston crowns, cylinder head, valves, and injectors, etc, not to mention EGR, I don't think that 35 mpg is unreasonable.

I would use Diesel fuel additives or just premium fuel with detergents, check the thermostat, and also use STAR to check for any fault codes, just to be sure.
 
My W211 320CDi (same 3 litre V6, just a little more powerful) has given just over 43 mpg (measured brim to brim, not using the trip computer) on a 200 mile trip to Norfolk on A roads and Motorway.

When I use it for general A road driving (rarely in the city) I average around 35 mpg.

The car is currently at 176,000 miles.

Not necessarily.

The OM642 is not as economical as the previous straight 6

Until the OP tries driving at motorway speeds for a decent distance (at least 100 miles) and calculates the consumption from brimming the fuel tank before and after the journey we will not have an accurate figure to work with.
