Two X5 second generation

[Bennettrindge]

Thanks for the info everyone. They are both straight 6 gas. I've used a generic scanner to get codes during limp modes. Once I was able to get codes 0087 and 10D9. They went away after a couple days, I have a great inde mechanic but he wants the engine light on to diagnose. He is an hour from me. He is conservative and doesn't like to start throwing repairs at it. He suggests possibly the hpfp. If I asked him to replace it he would of course. He rebuilt my transfer case two years ago for $850 after the dealership quoted me $3200 and it has been flawless ever since. I've never replaced tranny fluid for fear of slippage, that worries me the most.
