I sooked a few filter but never as bad as that. Not even after doing this:

My 2005 TD5 110 reverts to the low range throttle map if you floor the throttle. It's done it since l bought it in 2014, 36,000 miles ago.

Our 2006 90 TD5 did it from new for eight years and 44,000 miles. No solution was ever found.

On my 110 l have to take care not to press the throttle pedal right down, or l will spend the rest of the journey in the low range map.
lt still drives OK but you have to press the pedal further before the turbo comes in, and then it's more progressive in the power delivery.
Turning the ignition off then back on will reset it. Obviously not possible while driving.

£20 via paypal to anybody who suggests a solution which works (you'll have to trust my honesty with that)

Did you check your throttle position sensor? If the 3 tracks don't correspond you can get weird issues. My guess would be that there is a problem at full throttle position and the ecu will go to a different fuel map. Roel

Where is your air intake? I don't have any drains on mine as they are all sealed for wading bit mine has never looked like that!

The air intake is the standard wing-side grille. However, I've now discovered that the dump valve rubber teat is missing so it will also have been sucking air/water in via the bottom of the T piece where the dump valve should be located.

It has the ESR3162 which has some gauze/membrane over its bottom drain port, but it doesn't have an NRC8955. Shouldn't the NRC8955 rubber teat be attached to the bottom drain port of the ESR3162? I don't see it in the diagram

NRC8955 is for bottom air box drain

Problem not yet solved but I'm suspecting a drenched air filter was probably the root cause. I'm wondering if the dump valve isn't working properly - can it be removed for checking?

Wow. That is far worse than mine was. No wonder it wasn't running right.

It's a possibility, l'll see how much a new one is.
