Just recently bought a 2005 Smart Car.Car went into Limp mode after first fuel fill up.Read all the forum notes on here and tried everything.EGR is clean, Turbo turns freely, tried reset, tried battery off for a night, reset all error codes. Checked solenoid on EGR not sure if it works, or not, seems to we took it apart and check inside all seems to work fine. Reassembled it and put it back Only error code 403 comes on. Still limp mode.Bought all the part to make an emulator, but have not tackled that yet. Not sure if we are looking at the right area anymore. Dealer wants more to look at the car then it is worth. So question is any ideas? Anyone have an emulator in the Kelowna are we could try on this car to see if in fact that is the problem?Any advice much appreciated.HD
