i have a ford mondeo 1.8tdci 2009. i am having issues with acceleration usually in higher gaers. it happens more regularly on the motorway going up hill. i go to accelerate and theres no power. if i gently accelerate my speed will increase but very slowly and if i press to much on the accelerator it slows down.
Hi there good afternoon to you
Ok is this fault intermitent
Does it seem more noticeable on hard acceleration
Does it feel a bit like the engine is holding back /kanagrooing -jerking when fault is present

it started out intermitent but in recent weeks has become more consistant. it is definatly more noticible on hard acceleration. there is slight jercking when accelerating but i tend to back off once i notice it happening.

Hi thanks
Ok from your description of your issue I would suspect a partially blocked fuel filter
A lot of people overlook this as a root concern but over the years I have seen so many 1.8tdci with a partially blocked (emulsified filters )
On hard acceleration the engine demands more fuel thus if you have a partial blockage it's noticeable under hard acceleration
The filter should be replaced every 37.5k but I have seen them block a lot earlier
This would definatley be the first port of call with your symptoms
If you need anymore help or advice on this issue please let me know
If you are completley satisfied with my answer /advice
Kind regards ***** ***** and have a nice day
