Have recently bought my first Land Rover Discovery TD5 and I have to say I am really pleased with it. Have been reading through some of the posts on the site and have found them very helpfull .
I am interested in anything that I can do to give me more mpg, I have seen some web sites about remapping the ECU, is this really worth doing comparing the cost ?
Thanks for any help.

I,ll get in first, remove the EGR valve or blank it off, there are plenty of kits around on fleabay.

My EGR valve kit has just arrived from e-gay, will fit it over Xmas

I've been thinking about a re-map too, I'm fortunate as a mate of mine does it so it won't cost more than a few pints but is this wise on a TD5 that's done 98k miles?

What sort of power quotes have people had?

What Stig means is that there are no noticeable performance downsides. The EGR valve is there to recirculate dirty emissions back through the engine via the intake so that they can get burnt. This results in cleaner vehicle emissions and so is better for the environment.

In reality, the dirty emissions clog up the intake and restrict air flow, hampering performance. Blanking off the EGR then sends all the exhaust emissions out the exhaust pipe and not back through the engine. Results will give increased performance and economy at the expense of the environment.

do yourself a favor, find and spray the bolts with wd40, so when your EGR blanking plate arrives you can get it off...

Driving sensibly with a light right foot also helps with the mpg figures, as does staying below 70mph on a motorway

If you have cruise fitted (if not it is a VERY simple job on a 98+ model) try plodding along at about 62 - 65 and see what a difference it makes !!

Also another trick I tend to adopt is to not exceed 3k rpm (in ANY gear) !!

With fuel the price it is these days you have to do your bit, unless of course your very rich - then buy a 4.6 V8 supercharged Rangie and not give a toss what it does to the gallon !!!
