The reason I thought it might have been one of the knock sensors was that when you put your foot on the accelerator to get up a hill, the engine laboured and sounded as though it was knocking. Presumably that is the effect you get when the throttle is open but not enough fuel gets through. Fingers crossed it hasn't damaged the engine.
I guess knocking is a possible result of running lean. As you say, hopefully it's OK. I'm sure the engine management would have backed off the timing and kept it running as safely as possible.

I'm not jealous at all.

I live in the highest village in Hampshire. It's at 200m above sea level
I took my MV6 over the alps between Italy and Austria a couple of weeks back. It lost a lot of power at altitude but was clearly coping better than most cars! I even saw a couple of motor homes, though thankfully didn't get stuck behind them. There was what looked like a flat piece of road across the plateau (could have been on a gradient. It's difficult to tell when you've been climbing up through hairpins for an hour). I floored it and my car was almost maxxed out at about 75 MPH. A little bit less than at sea level then. Apparently

Have fun!
