I’ve had a 2014 EcoFLEX SRI for 6 years and it’s been reliable. Have had one failure of the thermostat which caused the car to think it had overheated.
Since then I’ve had an engine management light / loss of power due to a split inter cooler to intake hose and had faulty pressure sensors on glow plugs. Have managed to isolate the faulty glow plugs as x 4 of mine are pressure sensing and got away with replacing two.
I have had an oil pressure warning x 2 and will be replacing the pick up seal soon. I’ve done 80,000 miles over that time and its now up to 161.000.
WIth used cars there is a lot of luck and hope that its been looked after before.
