i recently brought a renault megane scenic dymonique that needed some attention. i had it diagnosed with the following faults:air flow sensor, egr valve,low batt voltage, wastegate fault. the car had no aceleration and stalled at a slight incline engine revs would not go above 2500 revs.......
so i replaced the air flow sensor,battery,egr valve, plugs,fuel and oil filters,oil and the tdc sensor......revs now went above 2500 at idle if acelerator pressed ,coped with incline,started and idled fine but still no aceleration it would take about 20 seconds to 40 with foot to floor and would not go above 50mph! so i had it re diagnosed all previous faults cleared accept egr valve so what could the problem be? is it in some sort of limp mode? how do i get the ems to reset to normal operation? i have no warning lights appearing on the dash to indicate problem.
also i have to replace the radios HUD as it shows only outside air temp how do i get the thing out?
