Default Freelander1 TD4 Fuel Economy

Hi all - I'm a newby so please be patient.

I have had my TD4HSE for 5 months. Had previously put disappointing MPG down to mainly urban driving but, on recent trip to French Alps cruising at 70-75MPH on motorways, only got 32 MPG based on odometer. Fear that in reality slightly less. Car has done 50K. I have read about replacing the MAF with Pierburg, about the synergy 2 from Rover Ron and about his Mafam. Have also read about cleaning the EGR valve etc.

My question is really about what sequence of things to try. For example, is it worth changing the MAF without getting a Mafam or synergy2? Should I clean the MAF sensor and EGR first and see how that goes? Just don't want to jump into high costs without making sure I try other avenues first.

Thanks in anticipation.

First problem is 70-75mph. Sure, the Freelander can do it easily thanks to the TD4 engine. However, poor aerodynamics will mean that it will come at a price. (I.e. increased fuel consumption) There's a reason why hatchback and saloon cars have completely different design characteristics when compared to 4x4s. The figures speak for themselves. The Freelander TD4 has a combined average of 37mpg while the BMW E46 320d saloon (same engine) can achieve a combined average of almost 50mpg. The BMW isn't that much lighter either.

I rarely drive more than 60 mph and when I do, I find myself filling up more often. Imo, the best thing you can do is to drive it as though you were driving a bus. Same advice can apply to all 4x4s. That should prevent you rolling it while navigating corners, and it will also reduce your fuel bill too!

you have to change how you drive to get a reasonable mpg mate.mines a td4 auto i only drove like a nutter once and i thought i had a fuel leak.like richm says 60-65 mph and you get a good return.i did a 140 miles yesterday with a car full of passengers and used 1/4 tank.not that bad

What tyres do you have and what pressures were they running at? How many times was the pressure checked on the journey?

Cheers

No need to start replacing parts that aren't faulty. 50k miles so should just have had a major service, if not get it done. Clean and disable EGR, clean inlet manifold if you wish, it can only be an improvement. Keep tyres at 30psi cold.
Auto should return mid 30s cruising, manual box should get high 30s.
Synergy 2 will be a good move for performance and will eek out another mile or 2 when going steady. Don't bother with the Pierburg maf.

Thanks for your replies guys. I understand about the nature of the car and aerodynamics etc but, if chaser is right in that it should do 'late 30's' when cruising (and I have read other posts indicating higher MPG), then I did not achieve anything like that. Can confirm tyres were at 30 psi. and that I drive very gently.

Obviously, if anyone has any other thoughts these would be welcome.

Otherwise I will take a look at the EGR and inlet manifold first and see if that makes any difference and will let you know.

Cheers.

Editted to make the point that you may well think you drive gently but you already said you were driving at 70 +

And remember the VCU dissipates energy, the faster you go the more it uses.

Hey Bromsgrove Defender - are you seriously suggesting that, in a Freelander TD4, doing 70-75 mph on motorways is less than gentle. This cruising speed is at 3,000 rpm - no where near the red line - and, in my experience, well within the comfort zone of a modern 2 litre diesel.

Why you should connect this to me 'red lining' at gear change is beyond my understanding - I operate within the lower end of the revs range in general day-to-day driving.

Bottom line is, should I reasonably expect anything more than about 34mpg combined and 32mpg on long run at these speeds? (Driving sensibly and never going anywhere near the red line).

If my expectations for something better are unrealistic that's fine. If not, I would like to know what I might do to improve things.
