    Manifold Pressure high logged 3030

    You insist too much on the gauge reading IMO, all i explained untill now is about the engine management, as long as you keep getting that fault code and those MAP readings that engine will not run well, it will be in the restricted performance mode regardless of what boost you see on the gauge

    Manifold Pressure high logged 3030

    IMO the essence is there ^^^ Thinking deeper it becomes more suspect to me that there is a short circuit to supply on the MAP circuit hence the "manifold pressure high" fault code which is logged after ignition when the ECU is going through the system test protocol cos then it gets around 4V...

    Manifold Pressure high logged 3030

    It should be quite the same as at idle, as you say close to barometric pressure and that's around 100kpa as the standard pressure at sea level 101.3(1013hpa) ... for the venturi effect extra pressure is needed not ambiental afaik that's the gist of it On a well working Td5 the MAP(manifold...

    Manifold Pressure high logged 3030

    If that's on the gauge it's irrelevant for the management, and as you said: "about 15psi" means about 1 bar(14.5psi) and that's a default mode for AAP sensor failure but i've seen this with MAP signal failure too even though it's not particulary mentioned it's still around 1bar(100kpa)... that...

    Manifold Pressure high logged 3030

    o_O ... you should explain that cos AFAIK for that some pressure is needed while at idle it's not. A 230kpa reading at idle for me can be a momentary short circuit between the sensor's supply and output wires so without any pressure the return signal(input) to ECU is above 4V and that can be...

    Manifold Pressure high logged 3030

    how would that explain 230kpa reading at idle ?

    Manifold Pressure high logged 3030

    It should be the other way around, about 100kpa at idle and go up to 230 under load, at this point i can presume a wiring issue or ECU fault try to read live data with sensor unplugged as well then read the code again

    Manifold Pressure high logged 3030

    I presume you replaced the MAP sensor did you? so if the sensor is new read live data with hawkeye and report what you get on the MAP sensor then we'll speak again

    Disco 2 reverse light switch with longer reach?

    The reverse light switch has only one p/n for R380: AMR3198 regardless if it's Defender D1 or D2 , i've seen this issue myself and one problem is that some cheap aftermarkets are shorter than genuines from factory but once there is wear inside de box even the genuine will not reach the notch so...

    Disco 2 CDL & Oil temp light

    There is an adaptor for that if your's has the CDL switch connector there, on some modells it isnt there at all, if you bridge the pins in it the warning should come on with ignition google out YQM105170 but you can cut that connector and fit two female spades instead to go on the switch on a...

    Flashing sign in milometer LCD and no indicators??

    I'd go for a good SH one to be 100% ruled out cos it can have invisible problems between the pcbs, unless you open it and see obvious corrosion and the pcb is not hurt bad... after you remove the retaining nut pull it as much as the wiring permits and start unplugging from one side... the more...

    Disco 2 CDL & Oil temp light

    Partially correct as it has noting to do if the box is manual or auto, it can be wired or not regardless of gearbox type but just untill one point under the dash from where the circuit is there for all hence all the previous discussion in this thread Not at all You have to cut only if you want...

    10p dead, upgrade to 15p

    Hi, just saw this thread, you need the 15P with it's own ECU, add one wire and plug for the 4 pin airbox sensor and add one wire to the 3'rd track of the TPS if it's missing(this one might be there) also a 3 track TPS if it's the early one on the vehicle... and a nanocom or similar to make the...

    Disco 2 Fuel tank removal

    For me is not very urgent so i'll drive it until the light comes on before starting the job ;)

    D2 TD5 fitting a water temp. gauge

    It should be IMO

    Heavy black smoke and very poor fuel economy

    I'm glad it was so simple as that. Bite the bullet and buy a genuine LR MAF then the vehicle will behave the best, if it seems too expensive to you get a Siemens/VDO one not other aftermarket cos for the 15P is way too important, better without it than with cheap ones... now it's on a default...

    Beeper refuses to shut up

    That might not be from the slabs... check if the HDC switch was not accidentally pushed

    Dynamic Antiroll error

    👍welcome, i'm always glad when it ends well, i'm sure that the problem is on that path anyway so if it comes back insist there, you should use some water repellent electric spray on C2396 something like this...

    Beeper refuses to shut up

    So confirm you hear only a random audible warning without any warning light on?

    Dynamic Antiroll error

    check the plug's pin disposals in the pic i posted, are you sure you measured across pins 1 - 2(first and second pins from left cavity side) with connector unplugged? pin 1 should be black/green not green/black according to the diagram, it's not the same thing(first is the main colour/second the...
