Electric range on my PHEV is reducing, what can I do?

I purchased a Citroen C5 Aircross PHEV in September 2021. At that time I was getting over 30 miles on electric power. This, as expected, declined during the winter and spring but when the weather warmed up the max I got was between 24 and 27. When it went for its first service there was an upgrade due. There were problems in that the upgrade failed and in the end they had to link their computer to Citroen for the upgrade to work. Overall the garage had my car for a week! The garage said they thought the upgrade should improve the electric range. This hasn't been the case and now I am only getting 18 miles. Can you advise on what I should do?

We have had a number of reports of this plug-in hybrid system (shared with the Peugeot 3008 and Vauxhall Grandland X) delivering disappointing range on a charge. Owners estimate a real-world figure of about 25 miles is possible, so yours seems low. Failing a trip back to the dealer, we'd experiment with using the car without the heater on (just using heated seats if applicable) to see how much the range improves. Keeping an eye on your driving style could also help: avoid abrupt acceleration and braking, letting the car coast or regenerative brake as much as possible. I'm afraid we're not aware of a real solution to the issue otherwise.
