Hi, Ron from Trenton Ont. Canada, I recently bought my 06 smarty fortwo passion cdi diesel with the excitement of fuel economy. I work on all my cars as best a backyard mechanic can do. I pride myself as having a descent eye for used cars and not scared to work on them as that's all I can afford, e.i.97 Toyota camray 140000 original kl and 98 Dakota sport 327000kl, 07 Mazda 6 340000 kl , all running like a top, But this one has me stumped with 3 bars flashing on dash X5 in the 2 month I have owned it and as lately po401 code EGR valve, next to no heat. Is this common with these cars or have I just got a lemon. I love this car if not only for the thumbs up or long stares or even the point and laughs. Im not giving up on it and I cant find a service manual so any and all help will be greatly appreciate
