Could be a sticking pressure relief valve.

Could be the oil pump is wearing out.

Could be main bearings worn but unlikely if it has been maintained properly.

I'd start by doing an oil change first, replacing the oil filter with a genuine Renault one. Use the correct grade oil. See if that cures the problem.
