Fuel drain

[Waleddiap]

Hello guys
I have travers 2011
My main problem is with fuel
From 1 month I noticed increase in using the fuel meanly the have of the tank =350 km
Before it was maybe 450 km
So I went to a grage for repairing it they do a major service and clean most of the inside parts change oil and air filter etc
when they done i take the car back while testing it I found the following
Half of the tank =150 km
What the problem in my car cause they want to change the fuel injection now it will coast a lot but idk if that is the problem or not also why after the major service the usage is increased for double

Do you have a check engine light on?
Have you actually tested kpg?
Fill tank, record how many kilometers you drive, fill tank, divide kilometers by liters.
What exactly did they replace other than air filter?
Does this shop work on alot of US cars?

Thanks for your reply
Yes I have check engine light on but it’s from 1 year and the car works without problems
I did that I filled the tank and go for 150 km and filled again it takes 39 liter this is huge
They replace the following Radiator assembly - water bump - thermostat- spark plugs - air and AC filter - belt alternator- oil and filter - oil seal front - steering overhaul with parts - front and rear brake pad
That’s all and yes they work on us cars

It's not working without problems you have a gas usage problem.
What is the code causing the light to be on?

I mean the usage problem was good until 1 month ago I felt there is more usage but it was not huge after doing all this maintenance and clean everything it becomes huge usage idk what happens now they say u need to change the fuel injectors

You could have another code causing the drop in fuel mileage. You need to post the codes you currently have.
