Hello together, for about 3 weeks the engine control light has been constantly shining during the ride. Then I drove to the workshop about 1 week ago, because my car had already started to go to the engine control light, but after a restart I thought nothing about it. But since the light was on now constantly I drove to Citroen to let the error memory read out. Out of that came only a fuse, and that the second car was constantly on. Then it was changed. After that it was quiet for about 2 days, then this damn engine control light went on again. I then checked the fuse myself, but that was OK. Then I removed the secondary air pump, and see there was a good half liter of water in the pump. I then cleaned it and dried it up and then installed it again. Since I could not delete the error myself then the day after I went to my workshop But now after 2 days the lamp is back on again. I checked the pump again, but it is perfectly fine and also runs who you start the car. Since I planned to drive to the TÜV tomorrow and the engine inspectors probably don’t like, I would like to know if there is any possibility, how I can delete the error myself. My car is by the way a Citroen C3 1.1 with first registration February 2005. Please help me! Thank you in front of ==References==
