My car did this last summer and wouldn t throw a code.
Smart car engine light on and loss of power.
If the pressure is low the fuel injectors will not be able to spray the correct amount of fuel into the combustion chamber and that will result in a loss of power.
The car s combustion uses gasoline and air to produce power where air first goes into the air filter.
To get the car out of limp mode turn the car off for 45 seconds untill you hear a relay click turn the car back on and you should be good to go until whatever causes the car to go into limp mode happens again.
The smart fortwo experiences a loss of power the engine switches to limp home mode and only revs up to 3000.
We have a 2005 smart 4 2 450 coupe problem first occurred a few months back driving along happily then lost power and ran rough with engine check light coming on managed to drive it the mile home and switched it off an don and was fine after engine light finally reset its self a week or two later same thing happened a few weeks later and.
The orange check engine light is a car s way of telling you something is wrong.
The fuel pump delivers fuel from the fuel tank to the engine.
The check engine light randomly comes on in my car.
If your car won t exceed 3000rpm about 90km h it probably went into limp mode.
It should never be ignored.
Sometimes your car loses power while driving due to a damaged air filter.
The fuel pump has to be powerful enough to be able to send the fuel at high pressure.
But the other day it got even worse.
It went on when i took the car back though.
The power came back after a few minutes but since then the alarm has sounded a few times even after switching it off or not locking the car.
I went to the dealer s several times but they couldn t diagnose the problem as there was no check engine light on at that time.
I took my smart roadster to the smart garage to ask them to look at the loss of power problem they have since rang me back saying there is a fault with it after they spent 45mins doing diagnostix on it sorry if i am vague here with details but not got a clue about cars they first said it was a problem connected to the wastegate pulse lead.
The power has been poor recently not beeing able to go over 60mph so unplugged battery hoping it would reset managemt unit.
If you have a bad filter your car will certainly have a problem in driving smoothly.
If you have a 450 these cars have a limp mode.
I had the cdi fix done.
Hi just got the engine warning light on on my 2010 cdi.
Recently my smart car alarm sounded and after turning it off i tried to drive the car but the engine light jad come on and the car lost it s power.
The filter keeps all the bugs and debris out from entering the chamber.
