Servus municipality, I have a problem with my c2 1.1 of 04, and that was the secondary air pump dismantled, because the motor allegedly attracts watery or dirt over time. however, all iO engine was like new, during assembly but silicone was used at least in the cover where the turbine wheel is screwed together with the last plastic cover. installed started motor jerks in the cold condition where the pump should run naturally so about 5sec. later again the e pump disassembled and seen that the turbine wheel with silicon fixed was all free made wheel can also be easily rotated only the safety skins after a few days out so few days goes well and then the pump no longer jumps on and safety is flat!!!!! I have already bridged with cable to battery there is everything iO. pump runs and sounds good. now my question can it be that maybe something else could have broken because the pump wheel does not get through the silicon could turn???? (except the 6 fuses) that broke me!!!! the next exhaust stings after sprit because not everything is burned, I think with the time of the time also not so good for because kat or? would like to have a info of you
