The smart fortwo engine suddenly shuts down when cold

You have recently met, the engine of your smart fortwo is cold. And it will suddenly go out. This is a malfunction that can be found on almost all vehicles. In this case, it will be necessary to check various elements. The pressure regulator . When cold, the pressure inside the engine is not necessarily perfect. A regulator malfunction can thus occur and cause pressure differences, and therefore engine shutdowns. Once the engine is warm, the pressure is regulated and your smart fortwo stops stalling. You must therefore check the condition of the regulator and perform a replacement if necessary. An electronic problem . It is absolutely the evil of the 21st century. Electronics offer many advantages in this industry, but also weaknesses. When your smart fortwo stalls cold, it can also be due to an electronic malfunction. A faulty sensor can transmit incorrect information on injection, for example, and cause engine shutdowns. In order to see more clearly, a check with the suitcase remains the simplest. An injection fault . It is a malfunction that can occur cold or hot. The consequences can fluctuate depending on the type of malfunction. Indeed, it remains difficult to determine an injection malfunction on a smart fortwo. It will be necessary to examine the proper functioning of all the components, injectors, pump, etc. It is therefore recommended to have a more in-depth check done by a technician. Here we have seen the particularly common problems of smart fortwo cold stalls. Unfortunately, this list is not exhaustive. The reasons for the problems are often different. Stalling for no reason is a roundabout signal of engine malfunction. A simple sensor or a simple seal can be the cause. In all cases, research must continue and this dysfunction can be resolved, which may tend to worsen.
