Hi, my name is Patrick and I own a 2002 C230 Kompressor with a secondary air injection malfunction and the car runs sluggishly when this problem occurs. Sometimes it goes away. Could anyone narrow down the possible problems?
Welcome to Benzworld. Have a look at the check valve and the shutoff valve they get clogged up with carbon and have to be replaced. I had this problem on my slk. Do a search you should find more info and some pictures.
