Diesels (newer ones especially) give worse results when you P&G.

They run lean under light loads and any attempt to accelerate even moderately results in much richer fueling.

Put your car in ECO and and press the accelerator to the throttle stop - that give about 80% load at most speeds and I've found is the best way to accelerate in a diesel Renault.

The only trick I have to share is once you're up to speed, lift off completely (wait for 0.0l/100km on the display) and then use the accelerator gently to maintain desired speed. This forces the ECU into lean cruise mixtures faster than if driven normally.
