We are having a weird problem with our Mondeo (diesel estate) at the moment and wondered if anyone can help?
Recently I've noticed that at higher speeds (usually around 50-60mph or more) the engine seems to be doing sort of pulses - regular surges and drops, as if the accelerator was constantly being pressed and released - around 1-second surges followed by the same time of lower power. It's audible and you can feel it, although it's not quite enough to visibly affect the car's progress (luckily!). Feels a bit like riding a cantering horse - leaping forward with each stride!
The car is a 2005 2l Mondeo TDCi estate. It's recently had a new flywheel and clutch (due to dreaded DMF issue) but the problem only started some time after that was done, so I don't think it's related.
Thank you!
