Hello engine talk community, I have a problem with my 3L Lupo Bj: 09/1999. I have the suspicion that the Eco mode only accesses the transmission control unit and not the engine control unit. Symtoms like Follows with Eco mode -It switches at low speeds into the next gear -When driving when the accelerator pedal is released the car goes in idle mode and when the accelerator pedal is activated the car lights up again – Green Eco lamp in the cockpit. -Wagen has Start Stop function at the traffic light at longer thru the brake of 4 seconds and again start at release of the brake These Sysmtoms are normal. Now the real problem -No power reduction in Eco mode -Whether Eco or not Eco always equal power -Consumption always remains the same -The consumption I never got below 3.6 liters at very eighth driving mode on the highway with approx. 100 km/h without city traffic -V- Max is according to Tacho and with a very long start This is not the same for me.
