sportage 2 1.7 CRDI

Complicated.

After first 1000 miles and the weather becoming warmer, the engine continues to run on and even accelerate AFTER I have taken my foot off the accelerator pedal. It will drive along for a distance at any speed without me re-touching the accelerator pedal. Last week continued uphill in a traffic cue at 5mph without me touching any controls. Coming off the motorway at 60mph braking down the slip road foot off the accelerator pedal, the engine continues its revolutions even when I have changed down a gear. Most disconcerting as I am braking against the pull of the engine. Does this at 40mph where I need to get down to 30mph. Garage says the engine operates at revs around 1500 RPM and the engine management system is designed not to let the car stall because this is low RPM for the car to operate at. They say I must follow religiously the small indicator on the dash board telling me to change up or down but it does not always appear. From observation I must be in 5th gear at 50mph, 4th at 40mph, 3rd at 30mph. Neighbour across has a Renault diesel and he says in 6th gear his management system maintains speed even though his foot is off the pedal. My car is doing it in nearly every gear.

At times do not feel in control of the car and none of this technology was explained to me when I bought the car. One of the benefits of a larger engine is that you do not have to change down every time as there is power in reserve to pick up again but I am now changing up and down every gear in relation to speed in order to try and contain the car. Previous car was a 1.6 Petrol Toyota and when I took my foot off the accelerator pedal, the revs began to reduce and I could tell from those revolutions when to change down.

I think the ECU on the Sportage needs tweaking but the garage are not offering to do anything. They have had a similar complaint from a new Ceed driver but from what they say, accepted the explanation.
