My average has gone from 26mpg to 29mpg since the clean and the sub 2k rev range is smoother.

See beginning of thread, link to instructions there. It's really easy, even I could do it.

preacher,
it's a very simple job, if I managed it, anyone can.

Remove oil filler cap, pull the engine cover off, replace oil filler cap, and you'll see where it is, just in front of the oil filter housing. Its fixed with a torx screw.

Just cleaned mine
Spent some time on Friday cleaning mine. After the bad times I had pulling the tin tent home from the Lakes last week . No better than 19mpg and embarrassingly slow i.e. 15 mph on the climb over Bowes Moor , I was imagining all sorts of expensive maladies being the cause!!
Please to say performance more or less back to normal. Not sure about fuel comsumption as only done town driving since Friday.
However pleased it was nothing more expensive than a couple of pieces of kitchen towel and six of my wife's cotton buds to fix !!!!

I used the Wife's cotton buds too. Cutting the stems in half at a shape angle helped scoop out some of the worst crud.
Anyway, now that a few weeks have gone by to counteract the placebo effect my rolling MPG average of 27.1 (displayed, not real) has increased to 29.6.
Perhaps a sub-conscious relaxation of the right foot may have helped but it looks like a real improvement. The car is mainly used for commuting to work which is about a 26 mile journey. The first and last 3 miles is city & town driving and the rest is rural A roads. Back in the days before the remap the mpg was a lot lower and the EGR blanking added another 1 mpg or so to my running average.
I cleaned mine back when this thread started and it certainly seems smoother unless its my imagination!
I reset my mileage etc on the 1st and since then havent been near a dual carriageway or motorway and showing 29.8. Prior to cleaning was around 24-25. The nearest thing to a good run was a trip to the Black Mountains yesterday with a couple of 1st gear climbs so well chuffed I started off with nothing and Ive still got most of it left.

Glad it's not just me feeling the difference in performance & thirst. Also noticed bit of foot ache if not using CC as right foot was a good bit higher for the same speed as before. Well no pain, no gain!

finally got around to doing mine today.
It's a 2005 with 73,000 mile on it.
I had the EGR blanking done a couple of months ago, so will keep on eye now I've clean off the gunk

My MAP sensor was gunked up too, I never used any cleaning agent though, just something soft strong and very very long ... yep I used a labrador puppy, no wait a bit of bog roll!
I would upload the picture but can't at the moment.
My normal journey to the nearest large population centre is 45 miles the first 20 of which are winding road and I have been running at about 28mpg as my norm throughout.
So imagine my surprise when today it hit 34.4mpg I can't recall the last time I saw those numbers on the dash.
Now I know the average mpg lie-ometer is not completely accurate but even so that's still a good improvement.

It's not the number on the dash as the trip does tell porkies! It's the difference as Porkie (new) - Porkie (old) is positive for same type of driving is the important bit. Good improvements being seen, plus a few long term improvements. Keep em coming, esp if improvements are there after few thousand miles.

Forgotten I'd done this, three weeks ago now.
Idly wondered why the old girl seemed smoother - credited that to the rainy weather (always seem to run better when a dry spell ends ), the indicated mpg is up about 2 mpg, too. Could be warmer ambient temperature, though.
New front disc pads also seemed to improve performance ; so it's possibly all placebo effect ; certainly braking IS better - have LR moved to softer friction material?
A2006 D3 finally swapped for a 2016 D4 Graphite in Graphite grey. No mods

Well Derek, I followed your instructions (in the other MAP sensor post) to the letter, here are my findings:
Body removed

Found both of my sensors (one was in the back of the Defender along with a ton of other bits!), both were really mucky and horrible

Especially the next one that was in my new engine

Both now cleaned off, time will tell the difference, so if anyone breaks one you know who to call Joined the BMWX5 45e group
1994 Defender 90
2015 RRS Corris Grey/Black roof
2016 D4 Graphite Santorini Black
2012 D4 XS Orkney Grey
2005 D3 S Maya Gold
