Thank you v much for this suggestion. I bought some of the metal woven braid wrap and also stainless tie wraps and now have them on the main cables. See the pic.
However, 2 days after getting the van back from replacing the sensor (££) I had an “oil sensor: workshop!” amber message come on! Today I’ve had the wheel alignment done at wheels in motion in Chesham (v good) and while they were at it they had a look and found yet another chewed cable to the oil sensor! Luckily they spliced a new cable in for me and it all seems ok for now but I’m guessing this can‘t be foxes and prob a mouse, rat or squirrel, since it was underneath the protective engine cover under the sump. V frustrating … it never seems to end.
