Hi can any one help. My mates c220 cdi coupe goes into limp home mode and the code P2080 comes up. I think it's the lambda sensors but he has been quoted £ 185 each can anyone help

Last time it happened it told him it was the egr valve so he changed it . He cleared the error code and the car drives normal again but now he's worried it's going to keep going into limp home mode

u can check map and boost control unit making sure it's not stuck and it's free when boost is on so it's not limping. Have u changed temp coolant sensor?
