Had the same issue about 5yrs ago, I changed the Suction Control Valve due to there being an upgraded part which has stronger springs inside the unit. Bought the part from a Diesel Specialist who sent me a OEM Part in a genuine box for cheaper than my local Toyota dealer (I'm a mechanic so was trade price) could sell me. Took 5 minutes to fit, I needed the spacer provided and the  ar has started up first time every time even in these current Beast from East conditions.

Is it as simple as changing the valve and it just works, or do you need to reset the fuel pump or ECU to get it to learn to operate with the new valve?

There are also some posts on here where people have said it's also necessary to get the ECU updated at the dealers to a new firmware version to get the full benefits.

Yeah it wasn't a complicated job, two bolts (possibly 12mm can't remember) and remove the old valve then fit the new modified one with the gaskets/ seals (everything comes in the kit). The first time I fitted it and started it up it revved flat out (so make sure you've started the car before doing this job to ensure the oil is around the engine!!!) so switched it off ASAP and fitted the spacer (in the kit) and restarted the engine and it idled at normal speed (around a 1000 rpm in my case, not sure if that's normal when cold but still). Unfortunately I didn't know i needed the spacer so it was just a case of try it and see but I now assume that you do need the spacer regardless.
