I searched around on here, and saw a recent thread about testing glow plugs, and all 4 of my measure at 2.2 ohms, with my multimeter leads measuring 0.2 ohms. I guess this means that they are okay...?
The car is high-milage at 155,000 miles, and has had an injector replaced recently (ish) (I assume as it's cleaner then the other three).
Any pointers as to what to check/clean to move down a list of things to tick off to try to solve this?
Many thanks for any help in advance!

The recent purchase/injector change may be of some concern ? However:
I had similar on my (long ownership 240,000 miles) V70 D5, where it recently developed rough idle on starting, with an occasional cut out and re start necessary. All glow plugs were (Vida) tested good, no (Vida) errors logged.
Solution, try a dose of, specifically, Liqui Moly DIESEL PURGE. It cured the issue for me. In my experience this stuff works. I have used it before in my other diesel Volvos. Ideally change the fuel filter and fill the filter housing with the LM when refitting, then run the engine as per the instructions.
I know there is a "snake oil" association with a lot of additive products, but I know this stuff has worked for me. Of note I have no affiliation with the manufacturers.
I am not saying it will cure your problem, but for around £10.00 it might literally be worth a shot, and worse case I doubt you will be any worse off, other than the £10.00 !
