    Td5 with altitude sickness

    ​My Defender 110 Td5 has developed some form of altitude sickness. The car runs perfectly well day in and out on sea level and on altitudes up to around 700m. If I drive at around 1000m altitude, the engine runs just fine and accelerates perfectly normal until it hits 2500rpm.Then it starts jerking/stuttering aggressively, dropping power and getting it back at a frequency of one per second. It is virtually impossible to accelerate beyond the 2500rpm in that situation.

    The turbo boost gauge doesn't show any fluctuation or movement up or down.

    All, I can remember having done around the engine lately, was to the the intake ducts apart and re fit & seal them with MAF friendly sealant. I also cleaned the MAF sensor twice, bit this didn't make a difference.

    Also, there are no fault codes logged.

    Cheers
    Joachim

    Have you checked for oil at the ECU due to the injector loom??

    Input for altitude come from the AAP sensor on the airbox lid.
    Disconnect it and it defaults to 100 kpa (sea level).

    See how that goes, it will tell you if the sensor is faulty or not.
    Hopefully just a clean as they are quite expensive.

    Do td5s in defers hit overboost? Sounds like what happens to my d2 - a half turn back on waste gate solved it.

    I think around the 16PSI mark. I have to admit, I was more concentrating on fluctuation than actual readings.

    What baffles me is that I had no issues for most of the two years, I've owned this car. It'd been happening for the last two and a bit months and is fairly consistent.

    What is the best way to clean the sensor?
