From the day I bought it new my 2008 Renault Megane sedan has given a cough whenever you suddenly want some power, like when you're starting off from a difficult intersection in traffic. It happens about three times a week, but I can't convince the dealer that it exists. They did 40 km in it one day, but you could do 1000 km steadily with no trouble. I have been increasing the revs a bit to say 1200 rpm when waiting in a likely problem area, with my foot on the brake, then I can get power without the "lurch" which upsets the passengers. I wonder about the fuel pump, but they checked the pressure in the fuel line and couldn't fault it. I have given up asking about it at the dealer's, but it drives me nuts and if my wife drives it, she drives me nuts about it! What should I do?

29 Mar 2013Now that it's out of warranty I would suggest you seek out a Renault service specialist and talk to them about it. It sounds as though it could be going lean when you give it a sudden burst of throttle. I would be cleaning the throttle body.
