After reading this, just checked mine, whoa, looked like a carbon mole hill, completely plugged up anyway, cleaned it as per most on here, bit of WD40 and the eye of a needle for the inners and then went for a check ride down the Autobahn
2007 (MY2008) 93K kms, TorqTune remap from TFC
Result, speed increasing had to back off when a truck pulled out on me another 10 kmh in there somewhere I think.

Well it does seem to have made a difference, definately appears to be a bit more responsive and the range on the tank has increased overall by about 80 miles, will see mpg when I top up on Fuelly, or is it all in the imagination? Joined the BMWX5 45e group

as a couple people have called me requesting new MAP sensors, due to, umm faulty cleaning
i have looked into them and realised the complete egr valve is cheaper than the MAP sensor alone

First long run - definitely 2-3 mpg better - definitely smoother, definitely a bit more poke.
But is it the clean MAP sensor , the new tyres*** or the new ashtray assembly???
***the new ATs - couldn't get any more AT2s apparently banned by EU drive-by noise regulations; new ATs all round. Lovely tyres, smoother drive but the drive-by noise as reflected by the M62 concrete crash barrier is WORSE 2006 D3 finally swapped for a 2016 D4 Graphite in Graphite grey. No mods

Nick, surely you mean the plastic chamber with the egr butterfly and the MAP sensor in it? Not the EGR valve itself

Weird thing re MAP sensor change for me was after cleaning it big improvement, then had remap applied and mpg fell 10%ish (before cleaning was -20%). Changed MAP sensor to nice new one supplied by St Nick and she's back to normal and mpg is where it should be for given type of driving.
Now leads to me thinking. I don't think there is a placebo effect, too many peeps reporting hard numbers being improved and with Berlin Warrior approaching V1 speeds it deffo seems to be doing something. As the MAP sensor governs fuel supply it makes sense when that plays up it's only going to increase mpg, we don't get lucky enough to improve things the other way. Is anyone at LR aware of this? Taken over the small sample above there must be tens or hundreds of thousands of car's affected out there. Apart from Nick, every time I mention it to a dealer or techie they either glaze over or have no idea what I'm talking about. Obviously it's not on the service schedule, it's not of any interest. I can be cynical in that changing more expensive parts is more attractive, but it's probably genuinely having no idea what is happening. I doubt LR themselves are interested in another thing on the service schedule, if they even thought there was an issue. The air filter is only changed every 45k, no way they are going to add annual checks to MAP sensors. If LRCS are watching these type of sites they would realise that there were issues, then dealers would be aware of things. Interesting thread on The Dark Side http://www.rrsport.co.uk/forum/topic22140.html?highlight= where LR Aus basically don't give a stuff re problems that aren't on their radar, to the point of hanging up on their customers, they have seriously lost the plot. Wonder if same here.
These ongoing problems for the last year (loads of ESF shutdowns, poor performance and dire fuel consumption) are part of the reasons I'm picking up a nice new Beemer tomorrow, not a D4 that I should have been buying. The line of 5 LRs as family car for us has come to an end.
Any way, where was I?? Keep checking your sensors peeps, together we'll save Da Planet.

Having done my flying "apprenticeship" on turbo charged piston engines (Pratt & Whitney Twin Wasp Radials rock), it amazes me that the TDV6 seems rather indifferent and largely insensitive to MAP. on a turbo charged aircraft engine, MAP is the parameter that is used to set engine power, ignore its limits at your engines life peril.Knowledge & Reason - the arch enemy of faith

Also surprised me that all was well after cleaning til remap applied, poss general use has a wider set of acceptable parameters, remap needs a tighter set that was outside those it was putting out.
Or co-incidentally the sensor failed when TorqTune was reapplied but doubt that. Anyone want a slightly (80k) used sensor??

Del....explain to my brain (we could be here sometime ).....as long as there is a hole surely it should be able to read the pressure ....no? If that is the case then the peeps who have had theirs completely covered with the gunk should therefore be the only ones with a possible sensor reading issue and therefore notice a change in performance perhaps 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Yes, if it's measuring static and not dynamic pressure (which I assume it is). Although if it's partially blocked the sensors response time may well be affected.Knowledge & Reason - the arch enemy of faith

DG, I'd agree except mine was only reasonably gunked, hole still there but as soon as I cleaned it the difference was immediate. In a static environment, no airflow, it would measure correctly with gunk on body but hole clear. Where there is airflow over the sensor that flow would be turbulent coz of the oil and not laminar so would/could change the reading due to the different way the air is moving. Comparison with iced up sensor tubes on aircraft, the hole is clear but the reading is wrong as the airflow is turbulent.
SWMBO's just reminded me i'm not an internationally renowned expert on MAP sensors, oh how cruel she can be!!

Just wondered as the reports back on a performance increase seem a bit vague on the circumstances TBH ...maybe a new poll del ? ...have to say though that a clean one must be better than a dirty one 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021
