Hello guys. Recently i bought E240 W211 2005y. Me and my friend decided ti change the engine from m112 e26 to m112 e37. Only the bottom of the engine and injectors were different so we did it. Car works like a charm but only when you delicate press the accelerator pedal.... If you try to make takeover or smash the gas the car stalls (closes the throttle instantly for a secound) and bring error P20D4 in ECU - Load limit exceeded. After reading almost whole night i see that there is some load/torque limits in EGS52 or/and in ECU. Do you know how can i get propperly change this in DAS without breaking the transmission? Help please.
