After spending hours of reading this forum I think a found something that is close to my issue. I would like to ask you for some help. I have w211 e280CDi engine OM642. One day my car started to jerking when pulling the throttle pedal so I found out that the turbo actuator could be the issue I resoldered the two problem contacts and the found the info about the resistor mod for swirl flaps - could they do the jerking? I tryied the resistor mod but for the first time no succes, the car drove but only for 50% of power no limp mode because the kickdown worked but the motor was very lazy. When I removed the resistor and made a test drive the car was with full force. So second time I tried another resistor and made a test drive and the car stayed with 100% power and I personally think it had better and smooth running and the gears were changing smoother as well. But after one hour of enjoyable driving and engine check light appeared and car went to limp mode (faults 2514,2526,2530,2527 appeared). So I removed the resistor and putted everything back to defaul nothing happened, engine check still on the dash. So I desided to check the fuses and found that fuse no43 is blewn - 15A. When I replaced it car started to work no limp mode I cleared the faults and no one appeared again. Before I tryied the resistor mod I didnot get any fault regarding the swirl flaps, I was only curious to try it if there will be some change in the engine behavior. So my question is could the resistor cause the fuse no43 to blow? If yes why?
The resistor used was 4K7 0,6watt
