Hi all on my 2002 Landrover td5 90
Having a really rough time trying to resolve this issue even giving in and sending it into a garage to resolve which they haven’t done although making me buy new (reconditioned) injectors
I’ve replaced the crank sensor numerous times, with oem and genuine ones no joy
I’ve also check the look of the crank sensor by running an overlay to the sensor itself, still nothing
Changed the ecu for one in a similar age disco td5 with the same ecu. Had garage reprogramme it to fit the defender and still no joy. Even now it throws up an ambient air pressure code on the nanocom and reads 80kpa whereas the original ecu which I had repaired by empire tuning shows a perfect aap pressure of around 100.
All my sensors are reading as they should such as maf
Changed the fpr and fuel pump
Put a decent starter motor on it in case it was giving a noisy signal
Tried putting the washer behind the crank sensor which didn’t seem to change the issue

I am now thinking I have a boosting issue as under high load, the turbo pressure is at 321 bar. Is that correct?

Any suggestions would be greatly appreciated

239°c?? And 321 bar ??
How is not on fire and climbing through the atmosphere??
Can you use another scan tool to verify the results

Seems that you have a power supply issue cos beside those ridiculous redings the battery voltage shows 0 and the ECU would not work well with that... is that with the original ECU or with the remapped disco ECU? though why was the original ECU repaired if the problem was with the crank signal?

also is the disco ECU NNN000120 ?

Sorry I was being a mug and clicked the wrong button on the nanocom!

I wasn’t using the nanocom correctly hence the stupid readings. I have a stock disco ecu with a stock defender map on it as I was told by the garage that my ecu could be causing a high speed crank code. However that is not the case as I still have that code coming up on the nanocom. Just replaced the actuator and made the turbo watergate false as loose as possible. I get a big boom of smoke come out the exhaust when it packs in and then it sounds as if it is misfiring.
