Can anyone help with my citroen c4 grand mk2. I had a fault with the Eolys system. Had a new tank fitted (£450 wasted) but turned out to be a faulty pin on the connection. So whilst trying to get the fault resolve it flagged up an issue with injector 3. Fault was cleared and didnt come back.
Since the eloy issue was resolved and the injector fault was cleared the fuel usage is high. Had my MOT today passed with no advisories or anything and they checked the injectors but nothing wrong with them.
Car has had a new battery, full service including oil and filters. So I'm not sure what could be causing the issue. Any ideas what to check as I'm getting around 100 miles less per tank using BP only to fill up so not supermarket fuel. I'll get the vin and add later once I've collected the car if needed.

Re: High fuel usage
What engine are we talking about? What sort of MPG are you getting? Have you checked for a dragging brake?

Re: High fuel usage
It's a 1.6 diesel and is currently doing 32mpg. I haven't had any symptoms of brake drag.
